Rose hips are the fruit developed by rose plants after bloom and they mature on the rose plant through the fall and often into winter if left in place. Most species of roses produce hips in some size and amount, but old garden, heirloom and classic shrub roses will tend to develop more of them than modern, highly bred cultivars, according to the University of Illinois. Pruning rose hips can be done at several points in their development, depending entirely on your goals for plant performance and the look you like in your garden. Rose hips are edible for humans and contain high levels of vitamin C and are prized by birds and other animals as a food source.
Step 1 Harvest fresh rose hips at their peak ripeness in the fall. The rose hips are ripe when they become swollen, the skin becomes a deep rich orange or a bright red, the skin is still relatively smooth and they give just slightly when pressed with your thumb. Allow roughly four months after the first flowers have been pollinated for rose hips to develop and be ready for harvest. Step 2 Groom the rose hip clusters on your plants during the late summer, fall or early winter by selectively removing single rose hips that may have become discolored, damaged or simply look unsightly. Cut the single hips on the thin, short stem that connects the single rose hip to the larger cluster and discard the cutting. Make the cut carefully so as not to disturb or sever the healthy hips from the cluster.
Step 3 Prune away any dried and dessicated rose hips leftover on the plant in early spring after the last hard frost has passed. During the winter, animals or inclement weather will usually strip the hips from the rose plants, but occasionally some remain tethered. Cut back the rose cane to a point of live wood, below where the hips are attached, just 1/8 to 1/4 inch above a healthy bud or leaf axil. The dried-up hips can be composted or discarded.

Roses are among the more difficult flowering bushes to grow, primarily because they are vulnerable to a wide range of plant diseases. Brown spots on rose bush leaves are among the most common problems encountered by gardeners. Those who wish to garden organically don't have the wide arsenal of chemical sprays to turn to that solve all your rose problems in one spray but may have deleterious effects on the environment. Fortunately, organic methods of getting rid of brown spots on rose leaves are available.
Step 1 Prevent brown spots before they become a problem by practicing careful watering and pruning. Brown spots on roses are nearly always the result of a fungus; hence, good moisture control is essential to keeping them at bay. Do not water the leaves of a rose bush, only the root area. Avoid allowing plants to become crowded, and don't plant roses in a high-humidity area of your garden, such as an area that receives less sun or where mold problems have occurred before. Prune rose bushes well to promote healthy growth and clean your pruning shears and any other garden implements that touch roses well, to prevent spreading mold from one plant to another. Step 2 Inspect plants to verify that the problem is, in fact, fungal. True brown spots always are; however, brown curled edges of leaves are a sign of scorching, and small yellowish spots can be a sign of insect infestation. Observe whether the spots are evenly distributed on the leaf or whether the browning is at the edges. If it is primarily at the edges, and the leaves are curled as well as discolored, excessive sun exposure is the culprit, and moving the plant to a shadier area after the last flowering is the best option. If the spots are yellowish, rather than brown, insects may be the cause. Look for bugs on the leaves to confirm. Organic insecticidal soap is the best bet for dealing with infestations.
Step 3 Spray rose leaves with organic fungicide if a fungal problem has been established. If using baking soda instead of purchased spray, mix one part baking soda with 15 parts water, and place in a clean laundry spray bottle. Re-apply fungal spray once a week and after any rainfall. If the infestation is small, remove diseased leaves and discard them in the garbage (do not discard them outdoors, since this can lead to the fungus spreading).

Knockout rose bushes are identifiable by their flower petals that bend outward instead of forward like most rose varieties. The center of the flower has a visible yellow or white section, unlike other roses. Because the Knockout rose bush is a hardy variety of plant, it can quickly grow out of control. Regularly pruning Knockout rose bushes will help control the plant's size and increase the number of roses the bush produces.
Step 1 Wait until late winter or very early spring to prune the Knockout rose bush, before it starts to regrow. Step 2 Examine the rose bush for any limbs that do not have any flower buds, that appear broken or diseased, or that are a darker color than the surrounding stems. Cut off these dead stems with pruning shears 1/2 inch from the base of the bush. Step 3 Locate two or three of the tallest and oldest stems near the center of the bush and prune them off 1 inch from the base of the bush using pruning shears. This opens up the bush and encourages new foliage to grow.
Step 4 Cut off 1/3 of each plant stem using the pruning shears to improve the plant's shape and promote additional blooms. Look for a small bud on the stem that is facing away from the bush and cut the stem just above the bud angled towards the rose bush.

Knock Out Roses are favorites with gardeners for their easy maintenance and long blooming season. In Georgia, they are versatile enough to thrive in all areas of the state. One of the only tasks needed to keep Knock Out Roses looking great year after year is an annual pruning.
When to Prune Prune Knock Out Roses in late February, recommends the University of Georgia Cooperative Extension Service. The last hard frost typically has occurred by this time, making pruning safe, according to the rose's developer, The Conard-Pyle Company. How Much to Prune Prune no more than one-third of the plant at one time, warns University of Georgia extension experts. Remove all damaged limbs or sections of the plant damaged by cold temperatures.
Touch-Up Pruning Knock Out Roses eventually shed their wilted blooms, but some gardeners prefer to snip those away promptly at mid-season for aesthetic reasons. It's also acceptable to lightly shape the plants during the year, if desired.

In 1988 rose breeder William Radler developed the Knockout Rose shrub, which has since proven resistant to cold climates and many common rose diseases such as black spot. The best time to plant your Knockout roses is dependent on your location and the maturity of the rose roots or plants you are planting.
Seasons According to Rose Gardening Made Easy, the best times to plant knockout roses are in the early spring or late winter if you live a region that experiences cold winter seasons. If you live in an area with a warm climate such as California, Texas or Florida, you can plant in the fall or early December. Root or Plant If you are planting rose bulbs or roots, you should plant them in the springtime to give them plenty of time to grow before the cold weather arrives. According to Rose Gardening Made Easy, rose plants can be placed in containers or planted in the ground during much of the year, as long as the ground is not frozen or water logged. Considerations Knockout roses have proven their hardiness and durability relative to other types of roses--they are winter hardy to USDA Zone 5 and heat tolerant throughout the U.S. However, a few environmental threats are common to all roses, including Knockouts. Frost and cold weather will stunt the growth of Knockout roots or young plants, and they generally don't fair well when their roots are left to soak in water.
Tips Wait until the last frost has passed before you begin planting. Check with your local nursery if you are unsure when it is safe to plant. Plant roses where there is plenty of drainage, and modify your watering patterns in accordance with heavy rain or prolonged sun and heat. In regions that experience especially cold winters, it may be necessary to provide protection for the knockouts in your garden; check with your local nursery for guidance.

Miniature potted roses accent a home's interior with beautiful rose blooms. Caring for mini roses indoors is similar to caring for full-size roses outdoors, only with less work. Indoors, the plant will typically be less prone to pests, and you won't have to worry about weather damage. Less care doesn't mean no care, of course. Keeping certain things in mind will help you maintain your mini roses.
Step 1 Keep your indoor mini roses in a sunny area of your home. The roses will not bloom unless they get enough sunshine. Step 2 Check the rose's soil for dryness each day. If you stick your finger in the pot and the soil is dry an inch down, you need to water. Water your mini roses deeply so the roots get a good drink--continue until the water starts seeping out of the drainage holes in the bottom of the planter. Step 3 Cut off old blooms with a sharp knife or pruning shears. Guide to Houseplants.com advises cutting the stem below the bloom at a 45-degree angle. This is a good time to check for insects on the roses. Deal with insects quickly by squishing them or spraying them with pesticide. Most houseplant pesticides will work fine for insects on mini rose plants.
Step 4 Fertilize mini indoor roses with the same fertilizer you use on outdoor roses. Many brands offer fertilizer geared towards roses. Only fertilize the roses when they're in their growing season (spring and summer). You shouldn't have to fertilize indoor potted roses as often as outdoor roses. Step 5 Prune off dead stems and foliage, cutting the stems at a 45-degree angle. Grow-Roses.com suggests pruning the mini roses back, leaving only 3 inches in height, when the roses are dormant in winter.

Roses range greatly in size and appearance depending on the type. They offer an appealing form and a pleasing fragrance but often have high maintenance requirements, insect and disease susceptibility and thorns. Knock Out roses, a trademarked variety, offer improved characteristics in some of these areas.
Knockout Rose The Knock Out rose is a type of modern shrub rose. It reaches a height of three feet and develops pinkish-red blooms. It is not one of the thornless roses. Benefits Gardeners appreciate the Knock Out rose for its disease resistance and drought tolerance. It also has lower maintenance requirements than many other roses; it does not need to be deadheaded throughout the growing season.
Thornless Roses Although the Knock Out rose is not a thornless rose, other thornless shrub roses do exist. These include the "Excellence von Schubert," a heat-tolerant rose with an excellent fragrance. The "Cardinal de Richelieu" grows four feet tall, with blooms that last longer than most other roses. The "J.P. Connell" shrub rose is a yellow thornless cultivar that is winter hardy.

The time to plant, and which variety of rose will succeed in your Ohio rose garden, depends on whether you live in north or south Ohio. Hybrid tea roses, for instance, require winter protection in northern Ohio, but not in the south. The time to prune a rose bush is the same, though, for all Ohio gardeners.
Significance Rose bushes require pruning for a number of reasons, chief among them is to clear out overgrowth to allow for better air circulation within the plant. Roses are susceptible to fungal diseases that thrive when air circulation within the plant is impeded. The Facts Ask any number of rosarians how to prune a rose bush and you will get that many different answers. There is no one "right" way to prune. At the least, prune to thin the growth in the middle of the plant. Cut branches that cross over one another and prune to keep the plant to the size you desire.
Timing Prime rose pruning times in Ohio gardens are during March and into early April. Heirloom roses, also known as old garden roses, should be pruned immediately after they finish blooming.

Life may not be a bed of roses, but growing a bed of roses (Rosa spp.) captures life's hopes and disappointments more than most gardening experiences. Not many plants trigger such anticipation with their burgeoning buds or bring such heartbreak when their buds fade to brown, taking the hope of headily fragrant blooms with them. In order to spare yourself from this fate, keep your roses' buds warm, dry and bug-free, and your rose bed clean. Depending on their variety, roses are hardy in U.S. Department of Agriculture plant hardiness zones 2 through 10.
Frost Damage Where mild winters keep rose buds coming, a few hours of frost can shrivel and brown them. Even worse, frost-injured rose stems, or canes, may develop a canker fungus infection. Avert disaster by watering your roses as soon as the forecast calls for frost. Moist soil retains heat during the day and releases it to the plants after dark. Cocooning the plants in bedsheets before the temperature dips below 40 degrees Fahrenheit minimizes their frost injury. Uncover them in the morning before they overheat. Gray Mold Infection Rose buds deteriorating into brownish-gray mush have Botrytis blight, better known as gray mold. Moist, mild weather with temperatures are 62 to 72 F encourages the fungal disease. The drooping buds may not open; if they do, the blooms may resemble brown pulp. As the infection moves down the canes, cankers mark its progress. Cultural Gray Mold Control Mail-order, bare-root roses often arrive with stowaway gray mold spores. Remove such roses from their packaging sleeves immediately, and plant them far enough apart so they have good air circulation. Keeping their leaves dry when you water the plants helps because gray mold spores need moisture to germinate. Remove old or damaged blooms promptly, along with the diseased plant parts and soil debris. Disinfect your pruning tools in a solution that is one part household bleach and nine parts water between cuts and after you finish pruning. The infected plant material should be disposed of in sealed plastic bags.
Fungicide Option Chronic gray mold in roses can be treated by spraying the plants with a premixed, ready-to-use chlorothalonil fungicide as soon as their buds break in spring. On a cool, overcast day with calm rather than breezy conditions, put on clothing that covers all of your skin, closed-toe shoes, a face mask, gloves and goggles, and spray the fungicide until it drips from the rose bushes. Repeat the application weekly while cool, damp conditions persist. Each time you use the spray, keep the area around your roses off-limits to people and pets during spraying and until the spray dries. Sap-Thieving Thrips Thrips insects invade rose buds with ease; placed end-to end, 25 of the yellowish-brown or black bugs stretch less than 1 inch. After overwintering as pupae in grass and soil debris, they ride spring breezes to plants, tunnel deep into developing buds and feed on sap or pollen. Brown-scarred bud sepals -- the narrow, green outer petals -- indicate the presence of thrips. The buds either remain closed or open with brown-streaked petals. In mild-winter locations, thrips may breed all year. Thrips Control Treating developing rose buds with ready-to-use insecticidal soap prevents damage from thrips. Unless the insecticidal soap's label indicates otherwise, spray the product every other day, coating only the buds until they drip. After drying, the soap won't harm lacewing larvae and other thrips predators. Flooding the soil around your plants periodically in late spring and summer drowns thrips pupae and interrupts the insects' breeding cycle.
