Growing Roses

Watering Roses

• Diligently water your roses. Soak the entire root zone at least twice a week in dry summer weather. Avoid frequent shallow sprinklings, which won’t reach the deeper roots and may encourage fungus. In the fall reduce the amount of water, but do not allow roses to completely dry out.
• Roses love water—but don’t drown them. That is, they don’t like to sit in water, and they’ll die if the soil is too wet in winter. The ideal soil is rich and loose, with good drainage. One of the worst mistakes you can make is to not provide adequate drainage.
• Use mulch. To help conserve water, reduce stress, and encourage healthy growth, apply a 2- to 4-inch layer of chopped and shredded leaves, grass clippings, or shredded bark around the base of your roses. Allow about 1 inch of space between the mulch and the base stem of the plant. See our Mulching Guide for more information.

Feeding Roses

• Artificial liquid fertilizers tend to promote plant growth that is soft and tender, and this type of foliage can attract aphids and other pests. Instead, rely on compost and natural fertilizers to feed your plants before and throughout the blooming cycle.
• Once a month between April and July, you could apply a balanced granular fertilizer (5-10-5 or 5-10-10). Allow ¾ to 1 cup for each bush, and sprinkle it around the drip line, not against the stem. See our fertilizer guide for more information.
• In May and June, you could scratch in an additional tablespoon of Epsom salts along with the fertilizer; the magnesium sulfate will encourage new growth from the bottom of the bush.
• Banana peels are a good source of calcium, sulfur, magnesium, and phosphates—all things that roses like. (Note that it will take longer for your roses to reap the benefits from bananas than it would with pure soil amendments.) Here are three ways to serve them up: 
  1. Lay a strip of peel at the base of each bush.
  2. Bury a black, mushy banana next to each bush.
  3. Chop up the peels, let them sit for two weeks in a sealed jar of water, and pour the mixture under each bush.

Pruning Roses

• When pruning, be judicious. If you prune too hard in autumn, plants can be damaged beyond recovery. Instead, wait until spring, when plants begin to leaf out for the new season. (Roses are often not the earliest plants in the garden to respond to spring’s warming temperatures, so be patient.) Give the plant time to show its leaf buds then prune above that level.
• Destroy all old or diseased plant material. Wear elbow-length gloves that are thick enough to protect your hands from thorns or a clumsy slip, but flexible enough to allow you to hold your tools. Always wear safety goggles; branches can whip back when released.
• Don’t cut back or move roses in summer, as they might suffer and die in the heat. Large rose canes can be cut back by as much as two thirds, and smaller ones to within 6 to 12 inches of the ground.
• Use pruning shears for smaller growth. Use loppers, which look like giant, long-handle shears, for growth that is more than half an inch thick. A small pruning saw is handy, as it cuts on both the push and the pull.
• Deadhead religiously and keep beds clean. Every leaf has a growth bud, so removing old flower blossoms encourages the plant to make more flowers instead of using the energy to make seeds. Remove any debris around the rose bush that can harbor disease and insects.
• Late in the season, stop deadheading rugosas so that hips will form on the plants; these can be harvested and dried on screens, away from sunlight, then stored in an airtight container.
• Stop deadheading all your rose bushes 3 to 4 weeks before the first hard frost so as not to encourage new growth at a time when new shoots may be damaged by the cold.
• Not all types of roses are pruned the same way or at the same time of year. Learn more here: How to Prune Roses.

Winterizing Roses

• Do not prune roses in the fall. Simply cut off any dead or diseased canes.
• Clean up the rose beds to prevent overwintering of diseases. One last spray for fungus with a dormant spray is a good idea.
• Stop fertilizing 6 weeks before the first fall frost but continue watering during dry fall weather to help keep plants healthy during a dry winter.
• Add mulch or compost around the roses after a few frosts but before the ground freezes. Where temperatures stay below freezing during winter, enclose the plant with a sturdy mesh cylinder, filling the enclosure with compost, mulch, dry wood chips, pine needles, or chopped leaves (don’t use maple leaves for mulch, as they can promote mold growth).
