In this case, simply clean the spent blooms away with your hand, leaving the hips. This usually means removing about one-half to two-thirds of the plant's height and reducing the number of canes. Grooming is a regular feature of rose culture, and the frequency will depend on the type of rose and your expectations. Other common pests of roses include aphids, spider mites, caterpillars, and flower thrips. Begin spraying as new growth emerges, and continue throughout the growing season.

Also, select roses that produce flowers with a single row of petals—many rose growers claim that the fewer the petals, the more shade tolerant the rose is likely to be. Roses can be grown satisfactorily near the coast with adequate soil preparation and maintenance and protection from salt spray. Most roses are not tolerant of irrigation water reclaimed or well water with more than 1, ppm salts. The best soil for growing roses is one that is well-drained but, at the same time, holds an adequate supply of moisture and nutrients.

Most Florida soils should be amended. Adding organic material such as compost, manure, or peat will increase the water- and nutrient-holding capacity and the overall health of the soil and the plants growing in it.

Soil amendments should be added to the entire bed not just to the planting hole because roots quickly grow beyond the amended area. Add 2—4 inches of organic material and mix amendments thoroughly and evenly to a depth of 12 inches. These materials are especially beneficial when added to light, sandy soils and to soils that compact easily. Where soils are poorly drained, it will be necessary to create raised beds. Nutrients are most readily available to the roots in a moderately acid to slightly acid soil pH 5.

Local nurseries typically have containerized roses for sale year-round, whereas dormant, bare-root plants are usually available from October to March. Be aware that bare-root plants are seldom grafted on 'Fortuniana' rootstock and therefore may not thrive in Florida. Roses can be planted year-round except in north Florida, where planting is best delayed until early spring. Repeated freeze injury to new shoots exhausts stored food and can kill plants that lack well-established root systems.

Compared to other regions of the US, roses in Florida grow larger and require more space than is recommended in other states. The space allowed for different plant growth habits ranges from a circle of one foot diameter for the smallest shrubs to a circle eight feet in diameter for the largest.

Dig a hole as deep as the root ball or slightly shallower. Remove the root ball from the container and gently loosen circling roots. Plant the rose at the same depth that it was growing in the container. This ensures that the graft union if it is grafted remains well above the soil. Fill the hole with soil and water thoroughly. Apply a 2- to 3-inch layer of mulch compost, wood chips, pine needles, etc. Irrigate frequently for 6—8 weeks to establish. Larger roses should be tied to a well-anchored stake or trellis for support.

Metal stakes made from pipe sections, electrical conduit, or reinforcing rods rebar are quite satisfactory. Cover the metal stake with clear plumbing tubing so that it will not scrape and injure the plant, and use durable, soft material for ties. Roses grow year-round in Florida; therefore, some maintenance is required throughout the year. Again, the type of rose you choose will dictate the maintenance level needed.

Most modern roses, hybrid tea roses, and grandiflora roses need weekly watering and spraying, frequent grooming to remove old flowers, fertilizing after each flush of bloom, and pruning and mulching in early spring. Cold-protection methods commonly used in colder climes are unnecessary in Florida because winter injury to mature wood of established rose bushes rarely occurs. More flowers are produced during summer than during cooler seasons, but flowers are larger, more intense in color, and have more petals during cooler periods of the year.

Frequent applications of water are necessary for modern roses and even low-maintenance roses will benefit from an occasional irrigation during drought periods.

When overhead sprinkling is used, water early enough for the leaves to dry before sundown. Microirrigation systems such as drip tubing or microsprayers are ideal because the foliage stays dry and less prone to disease. Fertilizing varies depending on the season, the location, and the size of plants.

Select a fertilizer formulated for roses, preferably one containing micronutrients and controlled-release nitrogen. There is little research on growing roses in Florida, but rose growers usually recommend that roses should be fertilized once a month from mid-February to mid-November, except in south Florida, where monthly applications can be made year-round.

Reduce this amount and frequency for small plants, old garden roses, and shrub roses. An organic mulch around roses will hold moisture in the soil and reduce weed growth. Replenish mulch as it decomposes. Remove weeds in rose beds by pulling them or by shallowly cutting them with a hoe.

Grooming is a regular feature of rose culture, and the frequency will depend on the type of rose and your expectations. Grooming consists of selectively trimming plants to keep them healthy, well-shaped, and productive. Dead-head remove faded flowers after each flush of bloom to improve plant appearance and prevent the development of fruit i.

This directs plant energy into new growth and blooms. Remove suckers leafy shoots that grow from the rootstock by breaking them off rather than cutting in order to remove all basal buds. Rootstock suckers can be recognized by their location below the graft union and their different leaf appearance. Remove dead wood and canes showing stem disease symptoms as soon as you notice them. Cut the affected stems back to healthy wood and remove it from the garden area.

To avoid dieback and encourage rapid repair, pruning cuts should be made just above a dormant bud eye. When an entire branch is removed, make a smooth cut where it joins the trunk. In south Florida, many rose growers prune these types in early December. Major yearly pruning consists of shortening main canes and lateral branches, and removing twigs and canes that are dead, diseased, injured, or spindly. This improves form, regulates height, and improves air circulation and light penetration within the plant.

Main canes that are one- to three-years old should be left at least half their length. The first flowers can be expected eight to nine weeks after pruning.

When cutting flowers, consider the arrangement in which they are to be used. Larger, more open flowers to be used low in the container need less stem length than tighter buds to be used for height Figure 3. Figure 3. Severe pruning of these roses would result in reduced flower production.

In their first two or three seasons in the garden, shrub roses can be left unpruned. Wait to see what shape develops and then try to prune so that the shape is maintained. Many modern shrub roses are pruned by a method called the "one-third" method. Suggested pruning sequence:. The result of this one-third method is that you are continually renewing the rose while at the same time keeping enough mature wood to ensure a good supply of flower-producing wood.

These roses are pruned much like modern shrub roses with some important considerations based on class. Old once-blooming roses such as Alba , Gallica , Centifolia , Damasks , and Mosses produce flowers on old wood, all pruning should be delayed until after flowering. Then, you do as little or as much pruning as is required to maintain the plant. Thinning and removing old wood is encouraged. These roses may not need annual pruning if there is no dead or damaged wood present. Repeat-flowering old garden roses such as Bourbons , Hybrid Perpetuals , and Portlands bloom on both new and old wood.

These can be pruned before they flower and pruned harder without fear of losing blooms. Climbers and ramblers may need a few seasons in the garden before pruning is necessary. In many cases, pruning is limited to removing winter-damaged wood. Pruning is similar for both classes. The difference is in the timing. Because ramblers are once-blooming, they are pruned right after flowering in early summer. Because climbers are repeat bloomers, they are pruned in early spring.

Reducing the side shoots or laterals to inches stimulates flower production, resulting in more blooms. Training canes to grow more horizontally encourages the growth of bloom producing side shoots. University of Illinois Extension. Focus on Plant Problems Hort Answers. Pruning Dead-Heading Dead-heading is the removal of faded flowers before they can develop seed. Dead-heading is also a good way to lessen the likelihood of diseases such a botrytis from becoming a problem General Suggestions The pruning of rose bushes can be confusing, especially when you start talking about hybrid teas, old garden roses, shrub roses, once-blooming roses, and English roses.

Basic pruning fundamentals that apply to all roses include: Use clean, sharp equipment. The cut should slant away from the bud. Entirely remove all dead or dying canes. These can be identified as canes that are shriveled, dark brown, or black. If cane borers are a problem, it is suggested to seal the ends of the cuts to prevent the entry of cane borers.

White glue works well. Remove all thin, weak canes that are smaller than a pencil in diameter. If roses are grafted and there is sucker growth, remove it. The best way is to dig down to the root where the sucker is originating and tear it off where it emerges. Cutting suckers off only encourages regrowth of several suckers where there once was one. Modern Ever-Blooming Roses Roses like hybrid teas, grandifloras, floribundas, and miniatures produce the best flowers on new or current season's wood.

Suggested pruning sequence: Remove all dead canes; cut them off at the base or point of discoloration. Remove small, weak canes.
