Selecting Your Roses [图片][图片]Roses are one of the most celebrated and recognized flowers in the world. With a little research or a visit to your local garden store, you will be able to determine which roses grow best in your area. How long it takes to grow roses depends upon the type of roses you select, the climate and soil quality in your garden. Roses are generally planted in the ground in early Spring in most areas but may be planted in late Fall in mild climates. Most roses will be ready for their first blooms in the summer. Floribunda, hybrid tea and shrub/hedge roses usually bloom six to eight weeks after planting. Climbing roses generally have a limited bloom during the first season but have a large bloom by the second year after planting. Purchasing and Planting Your Roses [图片]There are many different types of roses and their rate of growth is dependent upon the climate as well as the care they receive. To achieve maximum growth and blooms, select roses that are recommended for your area. If you purchased bare root roses through the mail, plant them as soon as possible. When you are ready to plant, fill a bucket with room-temperature water. Carefully unwrap the bare root plants from their packaging and then soak the root system in the water for approximately one hour prior to planting. Dig a cone-shaped hole 18 inches deep and spread the roots evenly. Remove any damaged, dead or broken roots and stems prior to planting. Add a mixture of soil combined up to a maximum of 25 percent compost and manure. Pack soil mixture firmly to fill in the hole and water. Potted roses should be watered and placed in a sunny location. If you are planning to plant the potted roses in your garden, remove any damaged, dead or broken stems prior to planting. Dig a hole, place the rose bush into the hole and add a combination the soil, compost and manure mixture which has been mixed with loose soil from the container. Water lightly. Growth of Popular Roses [图片]Producing the classic long stemmed roses commonly sold by florists, Hybrid Teas are one of those most popular variety of roses. Mature Hybrid Tea plants can grow up to five feet high. Also growing up to five feet and with similar blooms, Grandifloras produce clusters of hybrid-tea roses but with shorter stems. Climbing roses can be trained to entwine a trellis, a wall or an arbor but they frequently do not reach full blooming capacity until the second year of growth. Although they are usually between ten to twelve feet tall or wide, some climbing roses can grow up to twenty feet. Floribundas are easy to grow roses which generally bloom continuously from June until the first hard frost. Averaging between two and four feet tall, Floribundas feature clusters of flowers on short stems. Shrub roses are very hardy and will tolerate cool climates. Ranging between two to five feet tall, shrub roses will bloom heavily and frequently throughout the season. Due to their productivity, they have a large quantity of rose hips that need to be pruned regularly. Mini roses feature petite blooms and are available in a variety of colors. Most mini rose plants average approximately fourteen inches high but these hardy roses can reach a height of up to three feet.

Snow in summer is a lovely plant with grayish green leaves and bright white flowers in June. It spreads beautifully and is useful in rock gardens where it can cascade down amongst other creeping species. A non-flowering snow in summer plant might seem a mystery, but these short lived plants need dividing annually and well-draining soil to perform properly. If you have no flowers on snow in summer plant, you might just need to fertilize or consider a site change to optimize the plant’s lighting and soil needs.[图片]Snow in Summer Plant isn’t Blooming Great masses of white blooms on silvery gray foliage are the hallmark of the snow in summer plant. Failure to form flowers might be related to site conditions, lack of nutrients, or simply poor snow in summer plant care. Another common cause of no flowers on snow in summer plant is planting in the incorrect zone. This is an alpine plant that thrives in United States Department of Agriculture zones 3 to 7. Planting it in tropical to semi-tropical zones will not afford it the chilling period it needs to form blooms.[图片]Snow in summer plants form broad foliage mounds very quickly. They bloom in late spring to early summer, producing a carpet of bright white flowers quickly. The narrow leaves are evergreen and the plant will produce a 6-inch tall mat. In some climates, the flowers will self-seed if not removed from the plant. Fortunately, it takes to shearing or even a high mow to remove spent blooms and neaten the plant. When a snow in summer plant isn’t blooming, you may have sheared it at the wrong time. Trim plants after blooms or when flowers are just spent to prevent removing the next season’s bloom material.[图片]To keep your plant happy, install it in the optimum location. Snow in summer likes slightly sandy, well-draining soil in full sun. It prefers areas with cool summer months and does not like excessive heat. It is drought tolerant once established but will grow faster and better with average moisture. One thing that will really make the plant unhappy is compact, clay soil which doesn’t drain well. This can lead to root rot and could cause a non-flowering snow in summer plant but is more likely to affect foliage first and can even trigger total plant death. Over time, the centers of the plant will fail to bloom, but division of the plant in early spring or autumn will help produce more compact plants and better blooming.[图片]Snow in Summer Plant Care Once snow in summer is established, it is best to leave it on the dry side. Water only when the top few inches of soil are dry. The plant can be an aggressive grower but shearing it after bloom will create a tighter plant and prevent it from overrunning the planting site. Clip them back to 2 inches in height and the plant will rapidly produce new foliage and stems. Luckily, snow in summer plants have no serious disease or pest issues. Soil that doesn’t drain well seems to be their biggest problem. Overhead watering during the warm, moist months should be discouraged, as rust can become an issue.[图片]Fertilize in spring with a balanced all purpose, time release granule formula. This will feed the plant for up to 3 months, providing it nutrition to both flower and produce foliage. If necessary, you may want to encourage more blooms by using a high phosphorus fertilizer or adding bone meal to the soil around non-flowering snow in summer plants.

Roses are a favorite flower in America, gracing gardens across the country. When leaves start turning yellow, though, gardeners must diagnose and respond quickly if they want to keep their beauties blooming. Yellowing leaves can be a symptom of several maladies. [图片]Soil [图片]Roses like a slightly acidic soil with a pH near 6.7 and require nutrients to grow and produce well. A soil that is too alkaline or deficient in iron may cause general yellowing. Soil with excess phosphorus or potassium may need nitrogen to "green up" leaves. Culture [图片]Crowding can deny leaves the sunlight and air they crave, and they might start to yellow. Over-watering and too much fertilizer can also damage leaves, turning them yellow. Herbicides [图片]Pre-emergent herbicides used on lawns in the spring can damage roots of nearby plants, such as rose bushes, causing the leaves to turn yellow, and glyphosate spray, a common summer broad-leaf weed killer, may cause yellowing from the point of contact. Pests [图片]Aphids, spider mites, rose scales and leaf hoppers can cause yellow spots and patches on leaves. Use pesticides formulated for the particular insect infecting your roses. Fungus [图片]Fungi are transmitted by rain, wind, insects and gardening tools. Black spot is surrounded by a yellow "halo" and rust makes yellow patches with orange or black spores on the underside of the leaf. Prune the affected parts out of your rose bush. Virus [图片]Mosaic virus is a disease transmitted from a parent plant or by insects. It starts with yellow streaks on leaves.

Saxifraga is a genus of plants found almost everywhere on earth. Typically, the plants form mounds or creeping mats and produce tiny flowers. There are approximately 480 species of the plant, and plant enthusiasts and breeders are introducing more each year. A very common and easy-to-grow variety is rockfoil. Information on how to grow rockfoil plants will allow you an easy entry into this diverse and attractive group of plants.[图片]Rockfoil Saxifraga Information A commonplace form of Saxifraga is mossy rockfoil. There are many types of rockfoil, but mossy rockfoil is readily available in nurseries and garden centers. The mossy varieties are in the section of Saxifraga called hypnoides. The plant is an excellent ground cover, forming a thick tenacious carpet over rocks and under trees. Rockfoil produces its thickest and most lush foliage in spring. The bright green crinkly leaves pack tightly together and carpet rocks, pavers and lightly shaded nooks. In spring, tiny cupped flowers appear on slender stalks held above the body of the plant. The wiry stalks are tinged pink to purple and support blooms of salmon, pink, purple, white and other hues. The rockfoil flowers last into the early part of summer.[图片]Once the flowers die back, the plant is exposed to drying air and sun without their shading protection. This often causes the plant to die in the center. Fill in the center with a light dusting of sandy grit to help the plant hold moisture and prevent core mortality. This is important rockfoil Saxifraga information to preserve the beauty of your plant. The perennial plant needs moist shade and is hardy in USDA plant hardiness zones 5 to 7 in temperate regions. Growing rockfoil requires cool sites which mimic its alpine native ranges.[图片]How to Grow Rockfoil Plants Mossy rockfoil has no special needs, provided you give it a location with some shelter from wind and hot sun. The plants require moist soil, especially in spring when they are growing the most. You can plant this Saxifraga from seed but for faster plants, divide a mature clump. Seeds require cold stratification for germination and can take two to three years to bloom. Growing rockfoil from divisions helps prevent the center die out and gives you more of these alpine plants for your garden. This species needs a moist rich loam for best performance. Mix in a little compost with existing soil at planting time.[图片]Saxifraga Plant Care Mulch around the plants to conserve moisture and help prevent weeds from growing up into the center of the plant as it spreads. Water twice per week in summer. In colder zones, mulch over the plant lightly to protect the roots from freezes, but pull away the mulch in early spring. This allows the new growth to burst out without having to push through the layer of mulch. Mossy rockfoil needs no pruning and has no staking or manual cultivation needs. As with any plant, watch for pests and disease with Saxifraga care and maintenance. It is prey to several species of insect and prone to rots and rust. Combat these by avoiding overhead watering when the plant can’t dry out quickly and with a fungicide or baking soda spray.

The original Knock Out rose (Rosa "Radrazz"), hardy in U.S. Department of Agriculture plant hardiness zones 5 through 11, has exceptional disease resistance and requires little to no maintenance, including fertilizers. Joined by an expanded collection known as the Knock Out Family, the original Knock Out rose requires no fertilizer under normal conditions in healthy garden soil. With varieties hardy from USDA zones 4 through 11, Knock Out Family members share the same simple-care, low-nutrient requirements of the original Knock Out rose. If you choose to fertilize your Knock Out roses, timely applications and a light hand are essential. [图片]First-Year Knock Outs Although Knock Out roses don't require fertilizer at any stage of life, leaving them fertilizer-free is especially important their first year. Fertilizing newly planted roses can damage their tender young roots and delay the plants' establishment. Instead of fertilizers, focus on a proper planting site that suits Knock Out roses' other needs. Give your roses a location with well-drained soil and at least six to eight hours of full sunlight daily. More hours of direct sunlight translate to better health and more prolific blooms. Knock Outs do best in soil with a near-neutral pH level -- the point at which soil nutrients stay most available to plants. Established Plants If you chose to fertilize Knock Outs after they become established, wait until they have at least one full bloom cycle. Water before and after you fertilize them. Plants need water to absorb nutrients, and fertilizing dry soil can burn roots. Wait until the roses have 4 to 6 inches of new growth before you feed them in spring. Then wait until after the first flush of Knock Out blooms to feed them again. Use slow-release, water-soluble, granular fertilizer, with all three of its numbers -- for nitrogen, phosphorus and potassium -- in the single digits, and follow its label instructions. One rose food manufacturer recommends feeding Knock Outs 3/4 cup of 3-4-3 fertilizer per bush every six weeks during the active growth period. Work the granules into the soil around the roses, several inches from their stems or canes. [图片]Southern Considerations In most areas, Knock Out roses grow 3 to 4 feet tall, but long, southern growing seasons produce Knock Outs two or more times that height. Their blooms continue almost year-round in some regions. These hard-working Knock Outs may benefit from extra nutrients. Louisiana State University Agricultural Center recommends twice yearly Knock Out pruning, with each session followed by fertilizer. Frequent watering of container-grown Knock Outs leaches nutrients from their soil, leaving the roses short on natural nutrition. In both cases, follow through with 3-4-3 fertilizer or a similar product at the same rate as for established roses. Sterilize your pruning blades with household disinfectant before and after pruning each rose bush. Northern Concerns In northern climates, unfertilized Knock Out roses naturally wind down and harden off as winter approaches. They drop their leaves and redirect their energy to below ground. If you fertilize Knock Out roses in northern climates, stop providing all fertilizers at least six to eight weeks before your location's average first fall frost date. Late-season fertilizer stimulates vulnerable new growth and inhibits the rose bushes from entering dormancy, lessening their cold hardiness and putting the entire plants at risk of cold damage or death. High-nitrogen fertilizers are particularly harmful. In early spring, cut your Knock Outs back to 12 inches tall because they'll triple in height, but forgo the follow-up fertilizer.

Red clover is a common soil amendment and green manure. The plant fixes nitrogen in soil, enhancing fertility for better growth in other plants. If you are thinking about using red clover, why not try ornamental clover plants. Red feather foxtail clover has spectacular tufted flowers that are attractive and useful. Red feather clover not only adds nitrogen to soil but has other benefits after providing a colorful floral display.[图片]What is Red Feather Clover? Growing red clover to enhance soil is a time honored tradition amongst organic gardeners and traditional farmers. Trifolium rubens is an ornamental form of white clover, valued for its nutrient benefits and its lovely blooms. Ornamental red clover performs the same functions as standard red clovers while enhancing the natural landscape. Red feather foxtail clover is easy to grow from seed and needs little care or maintenance.[图片]This clover provides the most arresting floral display of all the species and attracts butterflies and hummingbirds. Bees love the flowers too! The plant grows 15 inches tall and has fuzzy purple to red flowers from early to late summer. It is an herbaceous perennial with characteristic clover leaves and a spreading stolen system that allows the plant to clamber over and cover large spaces. Red clover is even edible and can be used as a tea, animal browse, or sprouted for salads. If you are growing red clover for its edible or medicinal properties, make sure no chemicals are used in the area. Other benefits of growing red clover include its ability to break up soil and prevent erosion.[图片]How to Grow Ornamental Clover Plants Clover thrives in moist or dry conditions but drainage should be good. Slightly acidic soils with a pH between 6.0 and 6.5 are preferred. You can plant the clover in full sun or partial shade, although full sun provides the best yields. Sow the tiny seeds in a well-prepared bed from January to April or August to November. Plant seeds at ¼ inch deep or even scatter them on the surface of the soil and lightly dust them with earth. Keep them moderately moist until germination, which is generally 14 to 21 days. You may also choose to start plants indoors in flats. Transplant them outside when there are 6 true leaves and soil has warmed. Water established plants regularly. Choose your site carefully, as red clover has a tendency to spread and become invasive.[图片]Red Clover Care You may choose to cut back seed heads to prevent over-sowing of seeds and invasion of other beds. Otherwise, you can opt to till late summer planted clover in spring to increase soil fertility. Plants sown in late winter to early summer may be allowed to persist as a ground cover and cover crop to combat weeds and enhance soil properties. If you choose to harvest the plant for consumption, take fresh flowers and leaves at any time. Ornamental red clover can be harvested up to three times in the season. You may dry them or use them fresh.[图片]Sprouted clover seeds add a unique texture and flavor to salads and sandwiches. Soak seeds in warm water for 6 hours and then put them in a shallow bowl or seed sprouter. Place the container in a dark location for 3 days, rinsing and draining the seed twice per day. By the fourth day, you should seed sprouts and it is time to move them to a light location to develop green color and maximum nutrients. Use them as you would any sprout.

As gardeners, some of us grow plants for food, some because they are beautiful and aromatic, and some for the wild critters to feast on, but all of us are interested in a new plant. Unique specimens that will have the neighbors talking include Scorpiurus muricatus plants, also known as prickly scorpion’s tail plant. What is prickly scorpion’s tail and is Scorpiurus muricatus edible? Let’s learn more about caring for prickly scorpion’s tail.[图片]What is Prickly Scorpion’s Tail? Scorpiurus muricatus is an unusual annual legume native to southern Europe. Listed by Vilmorin in the 1800’s, the plant has unique pods that twist and roll in upon themselves. The name “prickly scorpion’s tail” was no doubt given due to the resemblance but its other common name of “prickly caterpillar” is far more apt in my opinion. The pods do indeed look just like fuzzy, green caterpillars. Scorpiurus muricatus plants are most often used as a ground cover. They have lovely tiny yellow flowers that are hermaphroditic, having both male and female organs. This herbaceous annual blooms continuously from mid-summer. A member of the Papilionacea family, the plants attain a height of between 6-12 inches.[图片]Caring for Prickly Scorpion’s Tail Seeds can be direct sown outdoors after all danger of frost has passed or inside for a jump start. Sow seed ¼ inch beneath the soil 3-4 weeks before the last frost if sowing indoors. Germination time for prickly scorpion’s tail is 10-14 days. Choose a site in sun to partial shade. The plant is not too picky regarding its soil and can be sown in sandy, loamy or even heavy clay as long as the soil is well draining. Soil can be acidic, neutral to alkaline. When caring for prickly scorpion’s tail, keep the plants moist to a little dry, not sodden.[图片]Oh, and the burning question. Is Scorpiurus muricatus edible? Yes, but it has an uninteresting flavor and is a bit prickly. It would make a great icebreaker at your next party tossed casually in amongst the green salad though! This plant is fun and a historical oddity. Allow the pods to dry on the plant and then break them open to collect the seeds. Then pass them on to a friend so he/she can gross out the kids with caterpillars in their food.

Knock Out roses are hardy down to USDA Zone 5. They can be planted outdoors in USDA Zone 7 (average annual minimum temperature range of 0 degrees F to 10 degrees F) in the spring after the last hard frost and in the fall, up to six weeks before the first hard frost. There are advantages and disadvantages to be weighed for the timing of planting that largely depend on your climate. In any case, it's best to avoid the heat stress of the peak of summer or the cold temperatures and hard-to-work soil of winter in most climates. [图片]Spring Planting Plant Knock Out roses in Zone 7 in early spring, after the last hard frost has passed. Spring soil is often wet and muddy, and rainy conditions weigh against spring planting. In climates where there are minimal spring rains, this is of little concern; in climates where spring rains are heavy, planting can be done on a dry day. Spring planting as early as possible (without frost) makes for a long growing and blooming season for Knock Outs, which will continue to bloom in cycles until the first hard frost of winter. Spring-planted Knock Outs will begin to grow again in two to three weeks after planting and come into bloom in six to eight weeks after that. Because spring-planted Knock Outs have the entire summer and fall to establish their root systems, they're well poised to survive winter undamaged. [图片]Fall Planting Plant Knock Out roses in the early fall in Zone 7. Planting Knock Outs in September, October and even the first week of November can be done safely. This allows the roots to become settled before the cold of winter. Fall planting also holds the advantage of a drier climate and better soil condition, which can reduce mildew and rust on the rose--though Knock Outs are known to be fairly disease resistant anyway. Roses planted in the fall are also more likely to bloom earlier in the spring because they're already well established. The downside of fall planting can be that the selection of roses available in your garden center and direct from growers is much smaller, unless you reserved or pre-ordered them.

Periwinkle, also known as Vinca or creeping myrtle, is one of the easiest to grow ground covers or trailing plants. However, its tendency to root at the internodes where stems touch the ground can make it an invasive competitor to other plants. Getting rid of periwinkle takes some serious elbow grease unless you wish to resort to chemicals. There are at least two useful periwinkle control methods in the following text.[图片]Periwinkle Control Methods Periwinkle is a very popular ground cover due to its glossy evergreen leaves and bright starry blue flowers. The plants establish and grow quickly, with remarkable tolerance to poor soils, unfavorable weather conditions and even mechanical damage. Mowing or string trimming the plant to keep it in a manageable condition works well in containing the tangled stems. But be cautious with the trimmings, as periwinkle will produce new plants with just a tiny bit of stem to ground contact, even once severed from the parent plant. This creates an issue, and many gardeners evince the desire to completely remove periwinkle ground cover.[图片]It may seem sensible to just pull the plants, but any little bit of plant material or the presence of underground stems will send Vinca growing thickly again in no time. The waxy leaves are quite resistant to chemical herbicides as the cuticle repels any topical application. Control of periwinkle must remove all of the roots and stems to prevent recurrence. Some plants can be grazed out, but periwinkle is not edible to grazing animals due to a milky latex sap. Manual removal is the least toxic method but the roots may grow several feet in the ground so deep digging is necessary.[图片]Control of Periwinkle with Herbicides Several states classify periwinkle as an invasive weed. For periwinkle weed control in large areas where digging is not practical, use an oil based herbicide. The cuticle on the leaves repels water based applications, but the oil base will allow the chemicals to adhere to the leave and gradually travel into the vascular system of the plant. Triclopyr mixed with mineral oil is effective but applications will need to be repeated as straggler plants crop up. Getting rid of periwinkle generally takes several seasons no matter what method you choose because of its hardiness and tenacity. Spray in winter when all other nearby vegetation has died back.[图片]Remove Periwinkle Ground Cover Manually Alright, it sounds like a pain in the-you-know-what, but manual removal really works best. Dig deep into the soil, starting at the edge of the problem area. Remember that periwinkle weed control relies upon complete removal of those roots, which may be several feet into the soil. Make a two-foot trench around the area and loosen the first section of roots. Pull as you dig further into the bed, loosening the soil as you go. The next season, if you see any small plants forming, immediately dig them out.[图片]In this way you will be rid of the ground cover permanently in a couple of years and other plants can take over the area. It won’t be easy, but it is a non-toxic removal that is effective.

Knockout roses are flowering bushes that produce large, bright flowers. The fragrance produced is not as strong as other varieties of roses, and the flowers do not typically last as long after being cut. However, the knockout rose is exceptionally easy to care for, and is resistant to drought and many diseases. The flowers can be pink, red or yellow, and will bloom throughout most of the year in warm climates. Planting Plant knockout roses in a location that receives between six and eight hours of direct sunlight each day. Ensure the soil is fertile and has high drainage; additional organic compost can be added if necessary. Plant the roses in late April, after the last frost of the season and when the soil has warmed to a workable temperature. Dig a hole 2 feet wide by 2 feet deep to plant each knockout rose. Transplant the bush directly into the hole and cover with soil. Water thoroughly after planting to compact the soil and collapse any air pockets. Watering Water the knockout roses two to three times a week until they become established. This will promote root growth, and help the plant create more food for developing leaves and blossoms. Reduce watering to about 1 inch per week after the first three months. Never allow the leaves to get wet, as this can cause disease. Water the roses as early in the day as possible, so any leaves that do become moist will dry out before the temperature drops in the evening. Mulching and Fertilizing Spread a 2- to 3-inch layer of mulch directly around the base of the knockout roses. This will help conserve water, maintain a constant soil temperature, add additional nutrients to the soil and discourage the growth of weeds. Replace the mulch after two or three months, or when it is visibly deteriorating. Feed the knockout roses with a balanced fertilizer with 10-10-10 NPK or similar. Spread between ½ and 1 cup of fertilizer directly around the base of the plants in late April. Continue feeding every four to five weeks until late August. Prevent root burn by watering the roses before and after applying the fertilizer. Pruning Prune knockout roses once yearly in late March. Remove any stems that are dead, dying or diseased. Cut back all other stems to a length between one and two feet. This will provide more air circulation and light to penetrate to the inner portions of the bush, reducing the chance of fungi or diseases.
