​Learn tips and tricks for growing roses -- a classic beauty and symbol of love.

Rose Gardening“The rose looks fair, but fairer we it deem For that sweet odour which doth in it live.” — Shakespeare

Loved for their beauty and fragrance, home gardeners are growing roses for a variety of landscape effects or for cutting. ​In fact, more than 1.2 billion cut roses are purchased in the United States every year, most of them on Valentines Day​ — Mothers Day comes in second.​ ​The members of the genus Rosa are prickly stemmed shrubs with a wide range of heights and growth habits. There are as many as 150-200 species and thousands of varieties, from miniatures (6 inches to 2 feet tall) to climbers that may grow 20 feet or more.

​Fun fact: Napoleon’s wife Josephine loved roses so much that she grew more than 250 different varieties.​

Quick Guide: Planting, Growing & Caring for Roses

  1. Roses require more attention than many plants
  2. Minimize additional care by choosing a variety well-suited to your region
  3. If possible, choose bare root plants over nursery stock in containers
  4. Choose a site in full sun; amend soil before planting
  5. Mulch well and prune carefully for plant health and ideal shape (see above)
  6. Protect against winter cold using straw and evergreen boughs
  7. Poor air circulation can increase pest infestations and disease
  8. Organic remedies are readily available

Sunlight: Full sun; shade decreases blooms
Maturity: Bloom time depends on variety: early, mid or late season
Height: 6 in to 20 ft. — miniature, ground cover, bush and climbing varieties available
Spacing: 24 inches apart

Site Preparation

Roses like a good, well-drained soil and will grow best in protected spots with ample water and full sun. Plants require at least 8-10 hours of sunlight per day for optimum growth.

Tip: If you have a choice between morning or afternoon sun, it’s probably best to choose morning. This will help dry moisture from foliage quickly and prevent many plant diseases.

Planting Roses

Bare Root

Planting from bare root stock is ideal because the plants adapt to your particular type of soil much better than those planted from containers. Also, bare root plants are much more economical to purchase and there is more variety at the nursery.

Keep the bare root plants damp until planting time. Dig a large hole, make a cone of rich potting soil at the bottom. Add some organic fertilizer to the soil mixture. We like to use a mixture containing bone meal, alfalfa meal and glacial rock dust. Place the rose in the hole with the roots fanned out over the cone.

It is important that the grafted section of the stem is not buried below the soil. Check for depth, then gradually fill in the hole with a mixture of the native soil and organic compost. Water immediately after planting to settle the roots in place.

Wait to fertilize until you begin to see new growth. December-April (depending on location) is the best time to plant from bare root.

Potted Plants

For a new site, dig a hole, which will vary depending on the size of the container, approximately 1 foot deep and add a nice layer (approximately 4 inches) of compost, well-aged animal manure or peat moss. Also spread on organic rose fertilizer. Dig this into the soil, mixing well. When planting, make sure that the grafted section, or bud union, of the stem is not buried below the soil.

Check for depth, then gradually fill in the hole with a mixture of the native soil and organic compost. Water immediately after planting to settle the roots in place. Do not fertilize until you see new growth.

Transplanting

The ideal time to transplant roses is when they are dormant in winter or early spring. If you must move rose bushes during the growing season, they will be put under considerable stress.

First prepare the new planting site so that roses can be transplanted immediately. It is important for the roots to remain protected in soil. Next, prune the top growth so the plants are easier to handle. Then dig as large a root ball as you can handle and move the plants to the prepared holes.

Don’t worry if you break a few roots — the reduced top growth will not require as many roots for support. Be very careful not to damage the trunk or branches during transplanting; injuries open the plant to invasion of fungal disease and insect pests.

Water immediately after transplanting and withhold fertilizer until you begin to see new growth.

General Rose Care

Mulching

A 2-4 inch layer of organic mulch will help deter weeds, improve the garden’s appearance and prevent moisture loss. Be careful to leave several inches around the stem of each plant free of mulch so fungus and pests can’t set up housekeeping.

Note: As mulches decompose, they use up soil nitrogen. Watch closely for signs of nitrogen deficiency and apply appropriate organic fertilizers if necessary.

Fertilizing

Roses appreciate an application of slow-release fertilizer in spring, midsummer, and again in the fall. Use organic fertilizer and add a tablespoon of granulated iron to the dry mix. Apply the fertilizer mix around the base of the plants, dibble it into the soil and water well.

Pruning

The ideal time to prune roses is when they are dormant, starting in January until just before the last frost in your area. The purpose of pruning is to improve the health of the plant and control the shape.

First, remove any leaves that remain on the plant. Next, cut out any dead, diseased or injured wood. Look for branches that are different in color to determine if they are dead. Usually dead branches are brown or black, but sometimes it’s difficult to tell. One sure way is to cut off a bit from the tip of the stem. Is it green inside? If so, then it is alive. If the stem is brown inside, that means it is dead.

Roses need excellent air circulation. Remove any large branches that run through the center of the bush. These will reduce airflow once leaves develop. Also, remove shoots that are growing across other plant parts and any thin, spindly stems that are smaller in diameter than a pencil. Make these cuts as close to the plant as possible (watch Pruning Shrubs for Color and Beauty – video). If you leave a stub, new growth will form there. One way to get close is to place the blade of the pruning shear flat against the stem.

The next step is to prune for shape. The ideal shape for a hybrid tea, grandiflora or floribunda rose is a vase shape. Picture in your mind an octopus with his legs slightly spread at the bottom. Now, turn him upside down. That is the shape you want for your finished pruned rose. The remaining stems should be 10-15 inches long, depending on the size and variety of the rose.

There is one more thing – each of the remaining stems should have the growth bud facing out. This is sometimes impossible to accomplish, but can be achieved after a few years of pruning. Buds are distinguished by a slight scar or line on the smooth green bark of the rose.

Old garden roses need to be pruned individually. Miniature roses just get a general all-over buzz cut. Shrub roses should be groomed and trimmed back to fit their environment, but no heavy pruning. After pruning, rake up any fallen leaves from under the plant because problem insect tend to overwinter in debris.

Climbing Varieties

After planting a climbing rose, leave it un-pruned for 2 or 3 years so it has time to become established. During this period, do general grooming and remove all dead, diseased or injured wood and the spent flowers.

Tie new canes into position on a trellis for support. In a few years, the plant will consist of only long canes, and from these branches, you will get the laterals that produce flowers.

Varieties differ in how they produce canes; some throw out new canes each year from the base of the plant while others build up a more woody structure and produce new canes from higher on the plant. Your objective should be to encourage new growth of the flowering laterals and to stimulate production of new canes.

For annual dormant pruning, remove only the old and unproductive wood. Then, cut back to two or three buds and all of the laterals that bore flowers during the preceding season. Canes that grow in the wrong direction should be trained, and removed only if they are uncooperative.

Winterizing

Where winter temperatures fall below 10˚F, roses need winter plant protection. The last fertilizer application should be timed so that the plants will stop producing flowers by the first projected frost date. The last crop of blooms should stay on the plant to form hips which will signal the plant to stop growing. The plants should remain well watered until the soil freezes.

After a few hard freezes, mound soil over the base of the plant to a height of 1 foot. In order to keep the roots protected, dig soil from another part of the garden, not from around the roots of the rose. Cut long canes back to 2-4 feet and tie them together with twine to prevent wind damage.

When the soil mound has frozen, cover the canes with evergreen boughs, straw or other material. This will prevent the mound of soil from freezing and thawing. You can remove this protective cover in spring when you are fairly certain that good weather has arrived.

Insect & Disease Problems

There are numerous problems with roses (too many to mention here). We have listed several of the more common problems below:

Mites
These tiny insect pests do their damage by sucking juices from surface tissue, causing yellowed, dry-looking leaves that sometimes show silvery webbing underneath. Spider mites are almost invisible, but their impact is seen in defoliation. To control outbreaks, spray horticultural oil on dormant plants. During the growing season, knock them back with insecticidal soap with pyrethrin.

Bud Borers
There are two destructive insect pests that bore into rose buds. Rose curculio are ¼-inch bright red, black-beaked insects. Rose midge are 1/16 inch, legless larva. Both of these pests bore into flower buds, preventing them from opening. Handpick if possible, or use botanical insecticides to prevent the spread of these destructive pests. Also remove and destroy infested buds.

Chafers
Rose chafers are an insect pest that chew holes in rose foliage. Hand picking is the best remedy, but any botanical insecticide will also work. Make sure to mix the spray with a little horticultural oil so that it sticks to the leaves and is there when the critters come to dine. Otherwise, it may wash away in the rain. Another option is pyrethrin spray, an organic insecticide made from chrysanthemums.

Leafcutter Bees
Cleanly cut holes in the foliage, either round or oval, suggest the activity of leafcutter bees. After damaging the leaves, these pests bore into the stems and canes to lay their eggs, causing wilt. Control by pruning out the injured tips several inches below the damaged area. Seal the cuts end of the cane with pruning sealer or grafting wax.

Botrytis
A fungal disease which makes the unopened buds appear rotted and gray. Pick off and destroy diseased blooms and spray plants with liquid copper to control. Provide excellent air circulation, and keep the area beneath the plant clean to prevent reoccurrence.

Powdery Mildew
Roses are especially prone to powdery mildew. It is a fungus disease that makes the leaves look as if they have been dusted with talcum powder. It is not especially damaging to the plant, it just makes them look ugly.

Avoid overhead water if possible and keep the area under the plant raked up and clean. Don’t plant anything under your roses to increase air circulation. Water only in the morning hours so the plants have time to dry during the day.

A homemade remedy made up from 1 teaspoon baking soda, 1/2 teaspoon oil in 1 quart of warm water mixed in a spray bottle will control the disease if applied on a regular basis. GreenCure® Fungicide is also used to control powdery mildew.

Black Spot
This fungal disease common to roses can be controlled by mulching under the plants to prevent water from splashing. The fungus spores that fall to the ground are carried in the splashback and the plant is reinfected. Keep roses clean, remove and destroy diseased foliage or debris from under plants. Avoid wetting the leaves (a soaker hose will help). Weekly applications of micronized sulfur may help to control problems.

Canker
Watch for this fungal disease that causes dieback on roses. Remove and destroy the injured canes for best control. This disease is spread by splashing rainwater, splash-back from watering, insects or dirty tools. Canker spores (PDF) can enter plants through pruning wounds.

Don’t stimulate new growth with fertilizer or pruning when you suspect canker. New growth is most susceptible. Keep the area around the plant clean and raked up. Pick or prune infected parts as soon as they occur. Liquid copper spray may have some effect.

Leaf Drop
Rose leaf drop can be caused by a number of reasons: lack of water, disease or insects feeding on roots, excess water if the plant is growing in a container, slow-draining soil or inadequate light. If you suspect any of these conditions, remedy the situation. For example, water more deeply, open the drainage hole in the container to improve drainage or treat for insect pests.

There are several diseases which cause leaf drop including black spot, apple scab and cherry leaf spot, all fungus diseases. Fungal disease can be treated by raking up the fallen leaves to prevent further spread and using micronized sulfur as a weekly spray treatment.

Yellow Leaves
There are several reasons why roses may develop yellow leaves. One reason is spider mite, a sucking insect pest; check the undersides of the leaves for minute webbing or dust size specks.Another more serious reason roses might develop yellow leaves is a viral disease infection; if you suspect viral infections, remove and destroy the plants.

Yellow leaves may also be caused by scale insects which look like small bumps on the bark, but they will suck the life from many types of plants, not just roses. Or, the plant may simply need to be fertilized.

Control the insect problems with Safer® Soap, and if you find scale insects, add a small amount of All Seasons Spray Oil to the mix.

Note: All plants shed leaves during the summer season. A small amount of leaf drop is natural.

    I need Help please my fiance gave me a rose today a whole 10 days before the anniversary of our first date. And the thing is he cares very much how I care for the things he gives me and I’m no green thumb so please help me figure out how to properly care for it. See the problem is my rose was a long stem… I guess and well it’s not any more the stem broke near the top. Is there a way to keep alive or use it to plant my own rose shrub? I don’t have the means to be buying bare roots to plant or anything like that so if there’s some way you can help please dodo! Thank you.
