Tree roses, also called standard roses, are bush roses that have been budded onto a tall stem or trunk. Tree roses grow up to 4 feet tall.
Types
Tree roses can be grafted from almost any rose variety. The most common types are hybrid tea, grandiflora and floribunda. Hybrid tea roses bloom on single stems and come in a vast array of colors. Floribunda roses are short, hardy bush roses that bloom in clusters. Grandiflora roses are like hybrid tea roses in their plant height and popularity as cut flowers, but have several blooms per stem and bloom more frequently than hybrid tea varieties.
Features
Prune tree roses according to the type of rose that is grafted onto the stem. Varieties that bloom only once per season should be pruned after flowering. Varieties that bloom repeatedly should be pruned during their dormant season.
Geography
Roses grow best in full sun and well-drained acidic soil with a pH between 5.5 and 7.0. Amend soil with organic matter prior to planting to encourage drainage and help prevent iron deficiency. Mulch after planting to a depth of 2 to 4 inches.

Lavender roses are quite often described as enchanting and irresistible. Traditionally, the color of this rose has been appointed to mean love at first sight, and is given between lovers as a sign of such enchanting love. Lavender roses are a nice addition to any garden, adding colorful variety and wonderful contrast especially when paired with white roses.
Blue Moon
A popular commercial variety of lavender roses is the "Blue Moon." This rose is a hybrid tea rose that will grow approximately 4.5 feet tall. "Blue Moon" lavender roses are known for their strong, sweet fragrance and large double-blooming petals. This type can be grown as a rose bush or as a climbing rose plant.
Angel Face
"Angel Face" is a lavender colored floribunda rose that will grow just about 4 feet tall. It has a sweet fruity fragrance and is typically a mauve lavender color. What is unique about "Angel Face" is that it will have a more blue lavender color in warmer climates. Resistant to most diseases, the "Angel Face" rose is easy to grow in home gardens.
Barbra Streisand
"Barbra Streisand" is another hybrid tea rose with a strikingly deep lavender color and a strong, citrus aroma. It has very large flowers and will bloom repeatedly throughout the late spring and early summer months.
Lagerfeld
Named after the famous fashion designer, the "Lagerfeld" is a beautiful pale lavender and light gray color. This grandiflora rose has an understated old-rose fragrance
Sterling Silver
The "Sterling Silver" hybrid tea rose is said to be the first lavender rose that gained popularity for its distinctly silver and purple color. While the color may not be as vibrant as other lavender roses, this classic beauty has a traditional rose smell.

Climbing roses provide a colorful accent that can be trained onto trellises, around windows and doors or along eaves. The old-fashioned blooms have new life with today's modern hardscapes and landscape structures. Roses need at least six hours of sunlight a day, and the Texas climate provides that in spades. Climbers can flower just in spring, or flower repeatedly, giving a color show well into fall.
Old Garden Roses
Roses in older gardens are often cultivars that don't exist anymore. They can be found creeping over walls and fences or even in cemeteries with no one to care for them. These climbers are being preserved through cuttings and reintroduced into cultivation. Schulenburg Apricot, Katy Road Pink and Highway 290 Pink Buttons are examples of some of the old garden roses. Old roses, which are any variety produced before 1867, are resistant to many common rose problems and can be trained as an espalier or trellis form. Lady Banks grows 20-foot-tall canes, and Cecile Brunner is not far behind with 15- to 20-foot canes. Either would be excellent choices for their old-fashioned pastel blooms and hardy climbing nature.
1950s Cultivars
A lot of new cultivars were introduced in the 1950s. One of these, Climbing Pinkie, is an 8-foot-tall bush with semi-double pink flowers. The canes are thornless and the blooms carry a light fragrance. Don Juan Is a citrus-scented red rose that blooms fully even in the worst Texas heat. For vigor you can't beat Dortmund, a 1955 introduction. It can grow up to 30 feet tall and bears deep red flowers with a white center and bright yellow stamen. The roses have overlapping petals that give the blooms a frilled appearance. The thorns on this bush deserve respect as they are large and sharp.
Earth Kind
Earth Kind is a designation from Texas A&M University that rates roses for their health, environmental friendliness and tolerance to Texas' extreme climate. Sea Foam is a moderate climber that only gets 3 feet tall and then cascades downward. None of the roses in the Earth Kind program have been treated with any chemicals or even fertilized. New Dawn was the first rose to be patented in the U.S. it is a fast climber that can grow to 20 feet tall, sporting white flowers with pink centers. Reve 'd Or is another vigorous species climber. The Earth Kind rose designation is now being used in other states to categorize rose bushes for responsible growers.

Cloning roses is the process used to grow a new rose from the cutting of an old one. Typically a cutting or piece is taken from a fading rose bush or from a bouquet containing a variety that appeals to you, and you'd grow the same variety from that cutting. Cloning a rose is a long process that requires patience and attention to the cutting. Often clones begin to show progress in as little as a week, but some rose varieties can take much longer.
Step 1
Remove your cutting from the plant below the point where the stem and main cane join (heel). An ideal cutting is 5 inches long with five groups of leaves (leaflets) and a spent (past bloom) flower.
Step 2
Wrap the cutting with moist paper towel and place it in a sealed bag.
Step 3
Add 1/8 teaspoon of Miracle-Gro and of baking soda (prevents fungus) and a few drops of dish soap into a 16-ounce spray bottle full of water and shake.
Step 4
Fold the top of a zipper bag down about 2 inches and pour three cups of potting mix in.
Step 5
Pour slightly less than a cup of water into the bagged soil and knead into the soil.
Step 6
Press the bagged soil down and poke a hole into the center of the soil with your finger.
Step 7
Remove the cutting from the paper towel and cut the stem about ½ inch above the leaflets at the top of the cutting.
Step 8
Remove bottom leaves, leaving one large or two regular sized groups of leaves on the top of the stem.
Step 9
Cut across the heel of the stem, or below the lowest point where the leaf stem joins the cane (eye bud).
Step 10
Dip the cutting into liquid rooting compound and place it slanted into the hole you made, pressing the soil firmly around it.
Step 11
Unfold the bag and spray inside with the spray bottle solution.
Step 12
Close the zipper from both sides, leaving an inch open. Blow into the bag so that it expands before closing it completely.
Step 13
Place the bag in an area with bright, indirect sunlight and watch for new growth.
Step 14
Remove dead leaves, bud, and fungus if necessary. If the soil cracks around the stem move it gently into the crack to firm it up.
Step 15
Spray inside the bag and re-inflate it each time you open it.
Step 16
Begin opening the bag (one inch for three hours the first day) when you see two or three new leaflets, growth at the top of the soil but no roots, or if you see new roots inside the bottom of the bag for several weeks. If it droops or the leaflets turn brown, blow up the bag and close it. Try again in a few days.
Step 17
Close the bag after three hours if the cutting is unaffected. On the following day double the size of the opening and the length of time you open it (2 inches for 6 hours).
Step 18
Continue opening the bag a little more each day for a longer period of time until the bag is fully open.
Step 19
Fold down the top of the bag once the bag has remained open for a full day with no ill effects to the rose, and leave it open for four days.
Step 20
Spray once each day after opening. You'll begin to see roots forming at the bottom of the bag indicating the rose is ready to pot after about 10 to 30 days.
Step 1
Remove your cutting from the plant below the point where the stem and main cane join (heel). An ideal cutting is 5 inches long with five groups of leaves (leaflets) and a spent (past bloom) flower.

No matter what the color, roses are beautiful flowers, but purple roses are particularly special. They are a symbol of enchantment to send to someone you admire. Roses of a purple hue are widely available, although less often seen planted in a garden or featured in a bouquet. Yet their unusual color is what makes them visually striking and desired by home gardeners wanting a distinctive colored rose to make their flower beds stand out.
Melody Perfume
The melody perfume rose looks like a quintessential red rose in shape, but differs in color. Its blooms begin as a medium-dark lavender and transition to a pretty lilac as they age. It's named for its aromatic qualities that can fill an entire room with its intoxicating scent. The rose bush is medium size, about 5 feet tall at maturity, and stands upright. It has shiny, dark green foliage. Plant this rose in zones 5 through 9.
Blue Moon
Blue moon is a hybrid tea rose. Its purple-blue shade is what makes this rose unique. Blue moon produces large, ornamental blooms. One rose generally grows at the end of a long stem, which makes it suitable for displaying in a vase. It's a fragrant rose variety, which has a scent similar to a sweet tea. Plant this rose in warm weather climates, such as zones 5 through 9. It requires full sunshine to grow lots of flowers. When cultivated in the right growing conditions, it produces flowers all summer and fall.
Burgundy Iceberg
Despite its name, the burgundy iceberg rose produces vibrant purple roses. This almost thornless rose variety has a mild sweet scent. Unlike other purple varieties, burgundy iceberg roses are hardy and tolerate cooler climates. Plant them in zones 4 through 9. Expect the rose bush to grow to 3 to 4 feet tall when fully grown. Burgundy iceberg is disease-resistant.
Veilchenblau
The unusually named Veilchenblau climbing roses have deep purple, flat petals with bright yellow centers. Streaks of white radiate from their center. Over time, their color lightens to a bluish gray. Flowers bloom in bunches. These hybrids produce one annual bloom. Cultivate it in zones 5 through 9 and train them to grow up a trellis or fence. They are drought-resistant and can handle moderately shaded areas.

Scientifically known as the Rosa rugosa, the beach rose is a sturdy, easy-to-grow shrub that enjoyed by landscapers and home gardeners alike. Not only are beach roses cold-tolerant and disease resistant, they will also withstand conditions that would send most rose bushes into a full wilt. They thrive in poor soil, salt air, windy environments and full sun. However, while they don't require the attention other rose bushes demand, they do need periodic trimming to look their best. Pruning beach roses eliminates old, unattractive or damaged wood, while promoting the growth of new foliage and flowers.
Step 1
Examine the rose bushes prior to the spring growth spurt. Not only will the beach rose recover more quickly from pruning during the dormant period, it will make spotting unwanted canes easier as there is bound to be little, if any, foliage on the branches.
Step 2
Remove any branches that have been killed by frost. These will be a dull brown color and will have no buds or new growth on them. Hold the pruning shears at a 45-degree angle and cut the branch, removing as much of the dead plant tissue as possible. Cut the branch back to the base of the shrub, if necessary. If you're not sure where the dead wood ends and the healthy growth begins, simply look at the center of a cut branch. Living canes are white in the center, while dead canes are brown.
Step 3
Trim any damaged canes, cutting them back to the place where they connect with larger branches. Additionally, remove any branches that are growing inward, toward the heart of the plant, rather than out toward the open air. This thins the shrub and allows air to circulate more freely around the branches, which helps to discourage the development of diseases.
Step 4
Eliminate crossed branches by cutting away the smaller of the two. If left unattended, the canes will rub against each other as they grow, damaging the protective bark and leaving the shrub vulnerable to invasion by pests.
Step 5
Examine the base of the shrub. Locate the bud where the branches emerge from the roots and trim away any growth found below this nodule. These offshoots are known as suckers and their development drains the energy resources of the plant.
Step 6
Sculpt and shape the shrub, if desired. Cut the canes back, removing up to one-third of each branch to control height. Alternatively, you can remove whole canes, cutting them completely back to the base of the shrub, to control the width. Take care not to remove more than 30 percent of the total plant material.

Sometimes roses are so beautiful that you may wish they would last forever. Luckily, with a bit of time and knowhow, your roses can be preserved. Although air drying is a simple, tried and true method, many experts believe that drying roses in silica gel is the best method of desiccation for roses and other flowers that have thick petals. Silica gel is a drying agent that will extract the moisture from the blooms while leaving their shapes and colors intact.
Step 1
Gather roses that are similar in size. If you are picking the roses from your own garden, harvest them in mid-morning on a dry day. Use only healthy, disease-free roses that are nearly at their peak.
Step 2
Remove the leaves from the stem and cut the stem down to 2 or 3 inches.
Step 3
Spread an inch of silica gel in the bottom of an airtight plastic container.
Step 4
Arrange the roses on top of the silica gel.
Step 5
Add silica gel around and on top of the roses until the blooms are completely covered with the gel. Add the gel a little at a time, jiggling the container after each addition to settle the gel around the roses before adding more.
Step 6
Check the roses after three to five days. Remove the lid and use a soft paintbrush to remove enough silica gel to enable you to access the rose. Touch a rose petal gently. The petal should feel papery and dry. If the rose isn't quite dry, replace the gel and check again the following day.
Step 7
Remove the roses from the silica gel when the blooms are completely dry, and use the soft paintbrush to gently brush excess silica gel from the blooms. Don't over-dry the roses, as the petals will become brittle and break easily.
Step 8
Create a stem with 20-gauge florist's wire. Push the end of the wire horizontally through the base of the rose, with about 2 inches of wire extending from the side of the stem base. Bend the short end of the wire down and wrap it around the longer wire and the rose stem. Cut the long end of the wire to the desired length, then wrap the wire with florist's tape.
Step 9
Gather a small bunch of about three to five roses with their foliage removed. Secure the bottom of the stems together with a rubber band.
Step 10
Hang the roses upside down from a hook in a dark, dry, well-ventilated room. Leave the roses for two to three weeks.
Step 11
Remove the dry roses form the hook. Spray the roses lightly with aerosol hair spray to strengthen their petals.

Aphids are one of the most common insects known to attack roses. The most common variety is the rose aphid (Macrosiphum rosae). You can use common ingredients in your home to make a spray to stop the attack of the rose aphid and other members of its aphid family.
First Defense
Start with a first line of defense. Give your rose bushes a medium to hard spray of water from your garden hose to get rid of the aphids.
Soap Spray
Make a spray that only contains dish detergent and water. Use a ratio of 2 tbsp. of dish detergent for every gallon of water. The ingredients should work to dry out the aphids and kill them.
Basil Tea Spray
Take a 1-gallon container and fill it with water and basil clippings. Let the container "steep" for a week. Add 2 tbsp. of liquid detergent and fill a spray bottle. Store and use this spray as a deterrent and preventive measure -- versus a solution once roses are infested.
Kitchen Cupboard Combination Spray
Use common "kitchen cupboard" ingredients to make a spray. Use a spray bottle and mix one-quarter tsp. of vegetable oil, one half tsp. of dish detergent and 1 qt. of water. Spray the roses, continually, every ten days.

Eggshells are calcium-rich organic material that decompose well when mixed into or layered on top of soil. Roses require heavy amounts of organic material to grow to their ultimate potential. Eggshells can be tilled directly into soil or added to compost or manure. Eggshells add nutrients, can help to stabilize the pH level and can act as a natural deterrent against pests.
Calcium
Plants, including roses, require large amounts of calcium in order to thrive. In terms of quantity needed, calcium ranks as a secondary nutrient behind nitrogen and potassium in plant nutrient needs. In plants, calcium helps to maintain the chemical balance of soil, increases metabolic rate and helps to neutralize cell acid. Egg shells are composed of about 95 percent calcium and therefore can provide roses with their full calcium requirement. There are no studies indicating harm caused by calcium overdose on plants, so tilling eggshells both into the soil and layering on top of the soil can be done simultaneously.
Lime
Aside from calcium, eggshells contain lime and protein. Lime is added to soil when it is too acidic (low pH level) to neutralize the acidity and raise the pH level. Roses grow best at a moderate pH level of about 6.5. Lime adds magnesium to the soil and helps increase aeration and drainage. Most commercial fertilizers contain lime.
Compost
Eggshells can be added to home compost piles to add calcium and lime to the mix. Eggshells act as an alkalizer when added to compost and do not change the nitrogen-to-carbon ratio. Home compost can be tilled into rose soil or crushed eggshells can be mixed into a commercial fertilizer or manure. Roses greatly benefit from large amounts of organic matter, the best ratio is 50 percent organic material to 50 percent soil.
Mulch
Crushed eggshells can also be scattered on top of the planted rose bed as a mulch. The nutrients seep into the soil with every rain or watering. To hide the eggshells, a second layer of bark or moss mulch can be layered on top. Eggshells placed on top and exposed to the air have a double use; aside from adding nutrients to the soil they act as a deterrent to slugs and cats. The eggshells lacerate a slug's underside, so slugs that crawl across broken eggshells turn back.

Home compost can be tilled into rose soil or crushed eggshells can be mixed into a commercial fertilizer or manure. Roses greatly benefit from large amounts of organic matter, the best ratio is 50 percent organic material to 50 percent soil.
Mulch
Crushed eggshells can also be scattered on top of the planted rose bed as a mulch. The nutrients seep into the soil with every rain or watering. To hide the eggshells, a second layer of bark or moss mulch can be layered on top. Eggshells placed on top and exposed to the air have a double use; aside from adding nutrients to the soil they act as a deterrent to slugs and cats. The eggshells lacerate a slug's underside, so slugs that crawl across broken eggshells turn back.

For many rose gardeners, the ultimate goal is to fill the garden with beautiful blooming bushes and the home with cut roses. Keep cut-rose bouquets looking fresh longer by storing cut roses at low temperatures, including in the fridge.
Temperature
Cooler temperatures help cut roses absorb nutrients from the water in the vases, and keep the roses looking fresh and new. Store roses in the refrigerator at temperatures between 32 and 38 degrees Fahrenheit.
Initial Arrangement
Keeping rose bouquets looking fresh begins with preparation: Fill a bucket with lukewarm water, recommends the Santa Clarita Valley Rose Society. Cut rose stems under the water to eliminate air bubbles. Allow roses to soak up the water overnight, then store in the refrigerator for about two hours. This helps prepare roses for display, preventing wilting and keeping blooms open.
Overnight Storage
After arranging roses for display, keep an area in the refrigerator free. Place the rose bouquets in the refrigerator before going to bed at night, and take them out in the morning. This will keep roses looking fresh longer than bouquets left at room temperature around the clock.

Roses (Rosa spp.) must be pruned regularly to be at their best. Some only need a light pruning, but others need to be cut back significantly once a year along with occasional tidying up throughout the year. The best time to cut them back in Texas and how hard they need to be cut back depends, to a certain extent, on the rose -- but the greater determining factor is where the roses are in Texas.
Roses for Texas
Roses are generally hardy in U.S. Department of Agriculture plant hardiness zones 2 to 11, depending on the species and cultivar.
'Fragrant Cloud' (Rosa 'Tanellis' or Rosa 'Fragrant Cloud') is a hybrid tea rose that has good resistance to rust and powdery mildew. It blooms repeatedly in spring and summer, producing 5-inch diameter orange-red flowers. 'Queen Elizabeth' (Rosa 'Queen Elizabeth') is a grandiflora rose that blooms from spring to first frost, producing pink, 2- to 4-inch wide flowers. Both of these roses do well in Texas and are hardy in USDA zones 5 to 9.
'Flower Carpet® Scarlet' (Rosa 'Flower Carpet® Scarlet,' USDA zones 4 to 11) is a groundcover-type rose that blooms in red from spring through fall. This rose is tolerant of high humidity and heat and has good disease resistance.
When to Prune
The best time to prune most roses is one month before the last expected hard frost in the spring. In Amarillo the last hard frost is usually around April 18. In Dallas it commonly occurs around March 3. Houston's last frost is usually February 8, while San Antonio gets the last frost around February 28. When roses are pruned earlier, they grow new stems and leaves at their bases and a cold snap is likely to cause serious damage or even kill the bush.
Climbers are the only roses that should be pruned right after they finish blooming.
Tidy up all types of roses at any time throughout the year by removing spent blossoms and dead and diseased stems as soon as they are noticed.
Pruning in Hot Climates
Roses should be cut back more drastically in USDA zones 8 to 10 in central and south Texas because the growing season is much longer there.
Large roses like hybrid teas, floribundas and grandifloras can be cut down to a height of 1 to 2 feet. This drastic pruning will result in larger flowers. If height is not a problem and such drastic pruning is not desired, they should be cut back by one-third their height.
Smaller roses like shrub roses, which includes 'Knock Out®' roses (Rosa 'Knock Out®,' USDA zones 5b to 9), should be cut back to 2 feet shorter than their desired height, but not by more than half their height.
Groundcover roses like 'Flower Carpet® Scarlet' can be cut back by about one-third their height.
If the roses did not shed their leaves in the winter, strip them all off. This makes way for new, fresh foliage for the coming year.
Pruning in Cooler Climates
Roses in the colder USDA zones 6 and 7 of north Texas will not need to have as much stem removed.
Larger roses can be cut down to a height of 1 to 2 feet, or one-third their height, whichever is preferred. They usually produce larger flowers when they are cut back to 1 to 2 feet tall.
Shrub roses and groundcover roses are cut back in cooler zones just like they are in the warmer climates of central and south Texas.
The leaves usually do not need to be removed in these colder areas. They are generally long gone by pruning time.
Pruning Basics
Always use sharp bypass pruners and make pruning cuts about ¼ inch above a growth bud. Disinfect the pruners with household disinfectant, rinse them and dry them off before using them. Also, when pruning diseased branches, the pruners should be disinfected between cuts to prevent the spread of disease. Wear heavy gardening gloves with reinforced palms and long sleeves for protection against thorns. Seal stems larger than a pencil with white household glue. Clean up all of the leaves, pieces of stem and other debris and put them in the trash. When left around the base of the roses, they will provide a growing environment for bacterial and fungal diseases.

Roses are some of the most popular flowers for home gardeners. Rose bushes grow and adapt to many types of soils. In fertile soils, rose bushes grow quickly and vigorously. Different varieties of rose bushes grow to different heights.
Bushes
Bush type roses include hybrid tea roses, floribundas and grandifloras. These varieties grow between 2 and 6 feet tall. Miniature roses are bush type roses as well, but they only reach 6 to 24 inches in height.
Shrubs
Shrub roses reach 3 to 10 feet in height. These varieties of roses include wild roses, hybrid rugosa roses and hybrid musk roses. Shrub roses are commonly used for hedges, ground covers and screens.
Climbing
Climbing roses produce canes that are 15 to 20 feet long and need support to stay upright. Climbing roses include ramblers, climbing hybrid tea roses and trailing roses. These roses are commonly trained to grow on fences and arbors. Do not prune climbing roses back until after the flowering is done for the season.

Gardeners may plant Knock Out roses for their reputation as carefree shrubs, but these varieties do require care, including some pruning. In Tennessee, the best time to trim Knock Out roses will depend on what garden task you have in mind.
Winterizing
After the first hard freeze in fall is the best time to trim Knock Out roses to prepare them for winter, according to the Tennessee Rose Society. The society recommends trimming out dead wood and cutting living canes back by about 1/3.
Spring Pruning
Do an early spring pruning of Knock Out roses after the last hard frost, recommends the Conard-Pyle Co. website, removing 1/3 to 1/2 of the growth, cutting back to 12 to 18 inches. In Tennessee, the best time to complete spring trimming is by mid-March.
Summer Sprucing
Although Knock Out roses don't require dead-heading to keep blooming, the best time to trim off the spent blooms to spruce up your plants during the Tennessee summer is after each flush of blooms. When the petals have dropped and new buds are forming, your shrubs will look neater if you trim off the spent blooms before they form rose hips. At summer's end, you can leave some hips until winterizing, advises the Tennessee Rose Society.

All roses, even the beautiful and hardy Knock Out, can sometimes have problems. While most of these issues will not kill the plant, they can cause leaf spots, yellowing, wilting and blight that may make it look like the rose is dying.
Pests and Disease
Black spot disease and mildew can still cause problems for Knock Out roses. In addition, pests like aphids, sawfly larvae and spider mites will often feed on Knock Outs. If left unchecked, these diseases and pests can weaken the plant and make it susceptible to disease and extremes of cold and heat.
Hydration
Roses do not like to have wet feet but still need adequate water. A good rule of thumb is to water 1 inch per week, 2 inches in arid climates or drought conditions. Mulch around the base of the rose to hold moisture.
Pruning
Knock Out roses should be pruned hard in the spring. Remove all crossing tips and branches, and thin the rose to provide adequate airflow.
Hardiness Zone Issues
Knock Out roses are considered to be hardy through U.S. Department of Agriculture Zone 5, but if you live in an area close to the dividing line between two zones, your roses may not tolerate harsher weather. Consider replacing your Knock Out with a rose more suited for your location.

The Knock Out® rose hybrids (Rosa "Knock Out®") began with "Radrazz" (Rosa 'Radrazz'), a cherry-red blooming, drought-tolerant rose with excellent disease resistance. More hybrids with different flower colors soon followed. While all Knock Out® roses are more resilient than most other types of roses, they still require supplemental irrigation when it does not rain.
Cultivars and Hardiness
Knock Out® roses are generally hardy in U.S. Department of Agriculture plant hardiness zones 4 to 11, although this varies slightly depending on cultivar. Fresh loamy soil should be piled up over the crowns of all Knock Out® roses to a depth of 10 to 12 inches for winter protection in USDA zones 4, 5 and 6.
'Radcon' (Rosa 'Radcon,' USDA zones 5 to 10) blooms in pink, 'Radcor' or rainbow (Rosa 'Radcor,' USDA zones 5 to 11) has dark coral pink flowers with yellow to pale coral centers and 'Radsunny' or sunny (Rosa 'Radsunny,' USDA zones 4 to 11) produces flowers that are gold-yellow in bud but change to bright yellow when they open and fade to cream-yellow. These Knock Out® roses all have single-form flowers with five to seven petals.
'Radtko' or double Knock Out® (Rosa 'Radtko,' USDA zones 4 to 10) produces cherry red flowers with 18 to 24 petals per flower. 'Radtkopink' or pink double Knock Out® (Rosa 'Radtkopink,' USDA zones 5 to 11) produces bubble-gum pink flowers with 18 to 24 petals each.
Knock Out® roses are shrub roses that grow to a height and width of 3 to 4 feet in cold-winter climates but can mature to 6 feet by 6 feet or more in mild climates.
When to Water
In mild-winter climates above USDA zone 8b, Knock Out® roses bloom all year round. This means they must be watered all year round in southern regions with warm, dry winters.
Knock Out® roses bloom from spring to first frost in cold-winter climates. In northern regions where temperatures drop below freezing in the winter, begin providing supplemental water in the spring when the ground warms and they begin growing, unless they are getting 2 inches of water per week from rain. Continue to water throughout the spring, summer and fall until the weather gets cold and they start dropping their leaves.
Amount and Frequency
Roses need to be watered more often when they are planted in sandy, fast-draining soil than when they are planted in loamy or clay soil that drains more slowly.
Newly planted Knock Out® roses need to be watered as often as necessary to keep the soil uniformly moist for the first one to two months until they get established. Give them 3 gallons of water, then check the top inch of soil every few days. When it begins to dry, give them another 3 gallons.
Give established Knock Out® roses planted in fast-draining soil 6 gallons or 2 inches of water each week when temperatures are between 70 and 80 degrees Fahrenheit. They may not need to be watered that often in slower-draining soil. Always check the soil before watering. If the top 2 inches is still wet, wait a few more days -- as a general rule, water when the top 3 inches of soil becomes dry. As temperatures rise to between 80 and 90 degrees Ft, Knock Out® roses may need as much as 9 to 12 gallons or 3 to 4 inches of water each week. Even more may be needed when temperatures exceed 90 degrees F.
How to Water
Water Knock Out® roses from below the foliage with a watering can, garden hose or soaker hose.Even though they are resistant to black spot and powdery mildew, it is better to keep the foliage as dry as possible.
Distribute the water evenly over the soil from 2 inches away from the stems and extending out about 1 foot beyond the drip line** or outer edge of the branches. Always water in the morning** so foliage will dry throughout the day if it gets wet, and the moisture will be available to the shrub in the heat of the day.
When using a soaker hose, set a 1-inch deep tuna or cat food can beneath the hose where water will drip into it to measure how much water is being delivered to the shrubs.
Spread a 2 to 3 inches of organic mulch over the soil around Knock Out® roses to help conserve moisture, keep the roots cool and reduce weeds. Pull the mulch a few inches away from the stems to prevent injury and disease that can result from the mulch keeping them too wet.
