Most cultivated rose varieties (Rosa spp.) are hybrids, rather than the natural "species" roses found growing in the wild. These wild rose species tend to grow vigorously, and require regular pruning to keep them in check. The best time for pruning wild roses is after they bloom. Wear gloves when pruning, because wild roses typically have many thorns. [图片]Wild Roses One wild rose so common it grows as a weed in some areas is the multiflora, or rambler, rose (Rosa multiflora). This plant grows in U.S. Department of Agriculture plant hardiness zones 5 through 8, and may occasionally grow outside this range. It is considered an invasive plant, but can be kept under control by removing new canes that sprout up throughout the growing season. Other species roses that grow wild, but don't spread as fast, require less severe pruning. They may grow in USDA zones 2 through 11, depending on the species. Pruning Goals Most cultivated roses are grafted onto a host rootstock, but wild roses grow on their own roots and send up new canes directly from the soil rather than a graft union. When pruning these roses, the main goals are to remove dead or diseased canes and give the plant an attractive shape. To thin the rose clump, remove entire canes at soil level. To encourage new growth or shape the rose, cut canes at a 45-degree angle right above the place where a healthy leaf meets the cane. The leaf chosen should be growing outward from the center of the rose plant. When cutting flowers or pruning canes, remove only about 25 percent of the rose plant's height. [图片]When to Prune Most pruning for wild roses should be done after the plant flowers. This pruning focuses on removing unwanted shoots and choosing four to eight canes that will be allowed to grow and flower next year. Wild roses, including multiflora rose, bloom on last year's wood, so heavy pruning in the fall or spring would remove the canes that will produce blooms. In fall, remove spindly growth and root suckers that have developed over the summer. In spring, remove only canes that died over the winter. Pruning Tips Use a pair of clean, sharp pruning shears or a pruning knife when working with roses. After pruning, cover the cut ends with pruning paint or white glue to seal the ends of the canes, advises University of Illinois Extension. This helps prevent disease and insect infestation, particularly cane borers. It is a good precaution to disinfect pruning tools after each use, to prevent the spread of diseases among plants. Do this by soaking the tools in a solution of 1 part bleach to 3 parts water for five minutes. After soaking, rinse tools with clean water and allow them to air-dry before using or storing.

The original cherry red-flowered Knock Out rose (Rosa 'Radrazz') and its varieties produce showy flowers and are relatively disease-resistant. The shrubs grow up to 5 feet high and wide, thriving in full sun and well-drained soil with a pH level between 6.0 and 6.5. [图片]Knock Out rose varieties produce 3-inch-wide, lightly fragrant flowers throughout spring and summer, and nearly all year in locations such as Florida. The blooms of Double Knock Out rose (Rosa 'Radtko') and Pink Double Knock Out rose (Rosa 'Radtkopink') have twice as many petals as the flowers of other Knock Out varieties, referred to as single Knock Outs. Single and double Knock Outs are hardy in U.S. Department of Agriculture plant hardiness zones 4 through 10 or zones 5 through 11, depending on the source. Pruning both kinds of Knock Out roses on a regular basis helps keep them healthy and shaped. Spring and Fall Pruning Single and double Knock Out roses benefit from an annual late-winter or early-spring pruning, whether they grow in cool or warm climates. Wait until the shrubs have had at least their second year of growth to prune them, however; they are mature then. The best time for spring pruning is when their leaf buds have swelled but before the new growth appears. In cool regions, the shrubs usually can be pruned from mid-February to early March or April. In warm regions, late January to mid-February is generally a suitable time to prune. You can prune again in late summer or early fall. [图片]Conditions That Warrant Pruning At any time of the year, you can remove dead, diseased or damaged branches from Knock Out roses. Although the shrubs tend to resist diseases, you may see occasional disease symptoms, including yellow leaves, peeling bark and a white, powdery mildew on the leaves and stems. Prune and destroy branches that show such symptoms; the disease-resistant plants probably will recover on their own. If your Knock Out rose bushes serve as a privacy screen, then an option is simply to remove their dead wood and allow the shrubs to grow taller. Promote air circulation and prevent diseases by removing branches that rub against other branches. Pruning Gear and Methods Wear a long-sleeved shirt and long, protective gloves to avoid injury from Knock Out roses' thorns. Prune the shrubs with bypass pruners, which have a scissorlike cutting action. Avoid using anvil pruners, which damage stem tissue, according to North Carolina Cooperative Extension. Before you prune, sterilize the pruners by soaking them for five minutes in a solution that is 1 part 70-percent isopropyl rubbing alcohol and 1 part water to prevent spreading plant diseases; rinse the tool with clean water. Also sterilize the pruning tool occasionally between cuts on the same bush and before you prune a different bush. Keep pruning tools and disinfectants away from children and pets. During spring and fall pruning, remove one-half to one-third of each Knock Out rose's growth,* but do not cut a plant shorter than 2 feet tall. Make each cut slanted and about 1/4 inch above an outward-facing leaf bud, with the cut slanting away from the bud. Staggering the cuts will give a shrub a dome shape. Removal of Old Flowers In summer, you have the option to deadhead, or remove, spent flower clusters from Knock Out rose bushes. Although deadheading is not a necessity, the practice helps control plant size and promotes late-season blooming. Deadheading is not a severe form of pruning and minimizes stress to the plants during hot summer months. Deadhead a faded flower cluster by cutting its stem just above the first five-leaflet leaf below the flower cluster. If you want to trim leggy or uneven growth, then make the cut above a leaf that is 6 to 8 inches below the old flower cluster.

Iceberg roses are one of the oldest and most beautiful of the climbing roses. The blooms are so white, they are almost blinding. However, they do not make good cut flowers for two reasons. Their stems are very thin, and they do not stand up well in a vase, and the blooms grow in clusters, so it is hard to cut without cutting off the new buds as well. But they make a spectacular display along a fence, on a trellis or over an arbor. These steps will help you with the pruning process. [图片]Step 1 Understand that iceberg roses should be pruned in the spring, when there is no danger of frost. Iceberg roses are hardy in zones 4A to 9A, so the exact time will differ depending on where you live. Roses are resilient, but if frost gets into a new cut, the stem will die. In the worse cases, you could lose the whole plant. Iceberg roses then need to be pruned during the growing season, and once again in the fall when they are prepared for the winter. Step 2 Keep in mind that spring pruning for iceberg roses is done in two different ways, depending on whether you want the roses to grow as shrubs about 3 to 4 feet tall, or grow taller as bushes. In order to make them grow as shrubs, you need to do hard pruning. This means cutting back the heavy wood more severely. But, this will keep the amount of flowers low. Step 3 Know that if you use the one-third method, you will encourage the roses to grow taller. Remove just a third of the oldest growth. This will leave you enough woody growth for new shoots to sprout from. Now choose a third of the best from last year's growth to replace the old ones that you cut away and remove the rest. [图片]Step 4 Remember that summer is the time to prune and shape the plant. Remove about a third of the flowering canes. Trim them short, to right above the five leaf section. There are two types of leaves on a rose plant. Some have three to a stem. Some have five. Look for the five. Also, remove the dead flowers, being careful not to cut off the close buds. Since iceberg roses grow in clusters, the new buds will be very close to the dead flowers. In the colder climates, do not prune too late in the summer. It will only make more growth, and you do not want it now. Step 5 In warmer climates, you will need to do pruning in the winter as well. In late November or early December, cut them back to about 2 feet high if you want shrubs and 3 to 4 feet high if you want taller bushes. Always prune with the shape of the plant in mind.

Bananas continue their usefulness even after you've eaten the fruit. The inedible peels provide potassium and magnesium to nutrient-hungry plants, including rose bushes (Rosa spp), which thrive in U.S. Department of Agriculture plant hardiness zones 3 to 11. Some gardeners also swear by banana peels' ability to deter aphids -- the bane of rose growers everywhere. If you're a banana lover, you have a few options for using the castoff peels to nourish and protect roses. [图片]A Banana a Day [图片]Whole peels deteriorate more slowly than strips or chunks, robbing your roses of the more immediate benefits of the decomposing plant material. Once you've peeled your banana, chop the peels into strips or chunks. This is also a good time to get rid of the blackened whole bananas you never got around to -- just chop the whole fruit, flesh and all, and mix it with the processed peels. If you don't eat bananas frequently, save the chopped pieces in the freezer, either in a jar or a tightly sealed bag. Daily Dose [图片]To feed individual rose bushes, gently remove about 1 inch of soil in a circular trench around the bush's base. After scattering the chopped peels in this circular trench, backfill it with soil and replace mulch, if necessary. If you have a rose hedge, work your way along the row over the course of the growing season. Dig a short shallow trench in front of a new section of the rose hedge each day, backfilling with soil and mulch as you go. When rotting fruit makes up a portion of the daily dose, digging the trench more deeply will deter foraging pests, as will mixing in wood ashes to neutralize the scent. Tropical Mulch [图片]If you have the room to spread out peels to dry them, you can make a material that mulches and nourishes your rose bushes at the same time. Spreading the peels flat on screens in a dark, dry room is the least labor-intensive method -- especially if you are consuming bananas during the roses' long dormant season -- but you can also dry the peels in a dehydrator or in a low oven. Once you've accumulated several pounds of dried peels, grind them in a food processor. Scatter this mulch around the rose bushes in the spring. Piling On [图片]Mixing chopped banana peels into the compost pile is another option for feeding rose bushes. This method is especially helpful if you either don't wish to bury the bananas around the rose bushes every few days or don't eat enough of the fruit to make feeding individual roses worth the while. Instead, mix the peels in with your other fruit and vegetable peelings, and toss them on the compost pile, where the peels will add their nutrients as they break down. It's best to either bury the fresh food scraps a few feet into the compost pile or mix them with wood ashes before tossing them on the pile.

Chameleon plants (Houittuynia) are a colorful ground cover in areas that might otherwise remain bare because of poor or wet soil. Chameleon ground cover is adaptable to many areas and can be useful in the landscape. However, chameleon plant care includes containing the plant and keeping its invasive tendencies within bounds. Chameleon ground cover, of the Lizard’s-Tail family, is attractive. Colors of red, bronze, cream, and yellow border green leaves when growing chameleon plants. Chameleon ground cover is an herbaceous perennial, dying back in winter. In June and July, inconspicuous flowers bloom, but are most often not noticeable.[图片]Containing Growing Chameleon Plants If you’re interested in having the chameleon plant growing in your yard, pond or bog, look at ways to minimize chameleon plant care by planting in containers and contained areas. Learning how to grow chameleon ground cover is not hard, once you’ve learned how to keep it under control. Growing chameleon plants need little encouragement. They can quickly cover an area. Just as easily, chameleon ground cover can get out of hand. Plant rhizomes into a large container and sink it into a hole in the ground in the area where coverage is desired. Get the chameleon plant growing near a buried fence or sidewalk that may limit growth and spread. Sprigs growing out of the designated area should be removed at the rhizome.[图片]How to Grow Chameleon Ground Cover Plant chameleon ground cover in a full sun or a partially shaded area. Best color develops in a sunny spot, but the plant remains vigorous in a shaded area. Have the chameleon plant growing in large areas where it can be mowed, if desired. You don’t want this plant growing near landscaped areas that it might invade. Avoid growing it near the porch or deck, as growing chameleon plants emit a fragrance similar to diesel fuel. Chameleon ground cover is useful around ponds and boggy areas where color is needed in wet soil. Pot chameleon plants as you would any other water plant and get them going for sensational interest in the water garden or bog.[图片]Now that you’ve learned how to grow chameleon ground cover and it’s pros and cons, plant it responsibly, so that it doesn’t invade forests and destroy native plants. Take advantage of this useful ground cover while keeping it under control.

Roses should be pruned each year to keep the plant healthy and promote the fullest and best blooms. If your rose bush has been neglected, it may not be too late to return it to a healthy status. Once you have cut out all of the old, dead or diseased canes, the plant gains increased air flow and you gain a healthy bush with blooms to enjoy throughout the growing season. [图片]Preparation Step 1 Put on a long-sleeved shirt to protect your arms from the thorns on the plant. Step 2 Wear thorn-resistant gloves. Leather or coated gloves are good choices. Step 3 Dip the blades of your pruning equipment into hydrogen peroxide to disinfect the blades before beginning. Procedures Step 4 Cut an area out of the side of the bush with hand pruners to allow access to the center of the plant. [图片]Step 5 Reach into the center of the plant to cut out dead or dried-out canes. Step 6 Cut out all dead canes at the base of the plant. Use the loppers for the thicker canes and the hand pruners for the smaller canes. Step 7 Select one-third of the remaining strong canes to stay on the plant. The canes should be about the diameter of a pencil. Remove the rest of the canes using the hand pruners. Step 8 Cut the remaining canes down by one-half to two-thirds of the plant. Cut the stems about 1/4 inch above an outward facing leaf bud at a 45-degree angle. The cut should slant away from the bud. Apply wood glue to the cut stems to seal them and prevent wood borers from getting inside the stems. Step 9 Trim all leaves from the remaining stems. Dig down to the root to remove any suckers. Tear them off where they originate to prevent additional suckers from growing. Step 10 Clean up any leaves that drop to the ground around the base of the plant to prevent the spread of fungal disease that may be present in the leaves. Apply rose plant food around the base of the plant.

Climbing roses are a great way to add new dimension--and height--to your yard or garden. They are typically easier to care for and more vigorous than other roses. If you have grown roses before, understand that caring for climbing roses is not exactly the same as caring for other types of roses. Although some of their requirements are similar, many things are different. [图片]Step 1 Plant climbers in an area that receives plenty of sun. While some climbers will do well in partial shade--even up to half a day of shade--most need plenty of light. In general, lighter colored climbing roses will be more tolerant to shade the darker-colored roses. Step 2 Amend clay and sandy soils with compost, manure, mulch or peat moss. Or plant the roses in an area that has rich, loamy soil with good drainage. Step 3 Cover soil with 2 to 4 inches of organic mulch such as straw, pine needles, buckwheat hulIs, ground corn cobs, peat moss, wood chips, shredded bark, cottonseed/cocoa bean hulls, chopped leaves, peat nuggets or grass clippings. This will keep the soil moist and the roots cool. Mulch in the spring while the rose bush is still dormant. Step 4 Water climbing roses, if necessary, so that they get at least 1 inch of water per week and 2 inches of water if planted in sandy soil. Water in the morning and avoid wetting the leaves to prevent fungus problems. Step 5 Fertilize in the spring after pruning. Use a dry, commercial rose fertilizer that has a slow release form of nitrogen. Apply about 1/2-cup to the soil. During the summer, apply a foliar spray of diluted liquid fertilizer (50 percent strength) every 3 to 4 weeks up until 6 weeks before the first frost is expected. Step 6 Support climbing roses by tying the canes to a trellis, frame or similar structure. Tie them loosely with string, soft cloth or plastic. Climbing roses do not have tendrils or suckers like vines, so they require external supports to grow vigorous. If possible, allow your roses to grow horizontally, than vertically, as they will produce more flowers. [图片]Step 7 Prune roses once they are at least 3 to 4 years old. In the spring, remove any dead wood, weak canes and any canes to avoid overcrowding or crossing. You will only need to prune every other year, although hardy climbers can be pruned every year. Your goal in pruning is to keep the roses in the area you want and ensure that only strong canes remain, not to limit its growth. Use only sharp, clean pruning shears and make slanting cuts about 1/4 inch above a growth bud. Step 8 Deadhead roses by removing any spent flowers. Cut back the stem to a leaflet or a bud with 5 leaves. Step 9 Protect climbing roses in the winter if you live in an area where temperatures frequently get and stay below freezing. For the best results, remove the canes from their support and cover them with soil. If you can't remove them from their supports, make sure they are securely tied and cover them with a burlap screen or similar material. Also, cover the base of the plant with soil or mulch.

Brass buttons is the common name given to the plant Leptinella squalida. This very low growing, vigorously spreading plant is a good choice for rock gardens, the spaces between flagstones, and lawns where turf won’t grow. Keep reading to learn more Leptinella information, including the growing and care of brass button plants.[图片]Leptinella Information Brass buttons gets its name from the small yellow to green flowers it produces in the spring. The plant is in the daisy family, and its flowers look very much like the centers of daisy flowers, minus the long white petals. These small, hard looking flowers are said to resemble buttons. Leptinella brass button plants are native to New Zealand but are widespread now. They are hardy from USDA zones 4 through 9, though just what that means depends on the zone. In 9 and 10, the plants are evergreen and will last all year. In colder climates, the leaves may die back. If protected by snow or mulch, the leaves will turn brown but stay in place. If exposed to the cold winter air, the leaves will die and new ones will grow in the spring. This is fine, though the new leaf growth will take a month or two to come back and the plant won’t be as attractive in the spring.[图片]Growing Brass Buttons Growing brass buttons in the garden is very easy. In cooler climates, the plants like full sun, but in hotter areas, they fare better with partial light shade. They will grow in a wide range of soils, though they prefer well drained, rich soil with frequent watering. They spread aggressively through runners just underground. You may need to dig them up and separate them every now and again in order to keep them in check.[图片]While some varieties boast green leaves, one particular variety that is very popular is called Platt’s Black, named for the garden of Jane Platt in which the plant was first documented. This variety has dark, almost black leaves with green tips and very dark flowers. Growing black brass buttons in the garden is a matter of personal taste – some gardeners think it looks on the verge of death, while others think it looks fascinating, especially interspersed with a bright green variety. Either way, the plant makes an exceptional specimen in the garden.

Miniature roses may look delicate with their tiny blooms, but they are a surprisingly hardy plant. Although they have been bred specifically to curtail their size, they retain much of the hardiness of rose bushes that tower over them in size. Many can be grown outside year round in zones 6 through 10 and will survive to zone 4 if heavily mulched and protected from winter weather. Their size makes them ideal as houseplants that thrive on sunny windowsills. [图片]Step 1 Plant miniature roses in all-purpose potting soil. Provide adequate drainage by covering the drainage holes with pebbles or broken shards from clay pots. Step 2 Grow on a sunny windowsill. Some require supplemental lighting. Watch your roses for signs of inadequate light. If the stems stretch leaving bare spaces between leaves, it may be an indication that the rose bush is reaching for more light. A miniature rose should be short and compact with full foliage. Step 3 Pinch out new growth to encourage the plant to bush out. This creates a full plant with abundant foliage. If the plant still stretches for light, you may need to add supplemental lighting. You can purchase grow lights for plants at your local hardware or garden supply store. [图片]Step 4 Place the pot on a pebble tray. Add water to cover the pebbles. The bottom of the pot should rest above the water level. As the water evaporates, it will provide your miniature rose with the added humidity it desires. Step 5 Keep the soil moist, but avoid soggy soil. Allow the soil to dry slightly between waterings. Step 6 Fertilize with a water-soluble fertilizer designed for roses. Mix the solution to quarter-strength and use to water the rose every seven to 10 days from March until November. Allow the plant to rest during the winter months and resume fertilizing in the spring. Step 7 Deadhead spent blooms to encourage the rose bush to continue blooming. Removing the flowers before they can set seed; this tricks the plant into thinking it has not produced enough blooms.
