Rose bushes require proper care to flourish. A preventative fungus spray and a jar
of soapy water can help trap summertime pests, while mulching conserves soil moisture
and controls weeds.

Recurrent blooming in bush roses depends on cycles of vegetative growth and flower
bud formation, which requires abundant nitrogen. Regular pruning and timely application
of fertilizer are essential to rose health.

## Pruning

The timing and methods of pruning vary by rose type, but the general aim is to remove
dead or diseased canes (stems) and encourage healthy growth. Prune hard in late 
winter or early spring as growth resumes, typically by mid-February in warm regions
and March in colder ones. When deciding where to cut, consider the shape you want
the bush to take, as well as how many blooms it produces. Prune out crossed branches
that rub against each other and remove stubby snags, which do not produce any new
growth or flowers. Also shorten sideshoots on shrub-type groundcover roses to control
their size, and trim back spreading ramblers to two or three buds.

In the Southwest, the bacterial diseases crown gall and cane blight kill many roses
each year, but vigorously growing plants are less susceptible to these afflictions
than weaker ones. Powdery mildew may also plague roses, especially if the weather
is hot and dry and the foliage does not get a chance to dry out. Frequent spraying
with a water hose in the morning or evening can reduce mildew growth.

To prevent fungus problems like black spot, prune roses after the first flowering
and use a general purpose fungicide in late winter. Spraying the leaves with a dormant
oil, such as Bonide’s Garden Rich Pruning Sealer, coats canes and buds with an antifungal
agent that suffocates the spores of overwintering fungi and halts fungal development.

## Watering

Roses require ample moisture to promote vigorous shoot and flower bud development,
but watering must be done correctly. Overwatering starves roots of oxygen and promotes
fungal diseases. Watering too often can also cause the leaves to wilt and drop off.
It is important to check the soil depth of moisture and aeration before watering.
Watering deeply is better than sprinkling since the soaked ground allows the water
to be absorbed more easily.

Rose bushes need about two inches of water each week (four to five gallons) in temperate
climates. More frequent watering may be necessary in sandy or very dry soils. Watering
should be done in the early morning so the plant can dry quickly in the heat of 
the day.

If you grow disease-resistant varieties, fungicides are not needed to combat common
problems like black spot and powdery mildew. However, it is still important to remove
faded blooms and dead stems from the plant, as well as improve airflow and keep 
the soil moist and cool to prevent fungus growth.

Mulching helps control weeds and keeps the soil cooler and moister, which reduces
the frequency of watering. A layer of 2 to 3 inches will insulate the shallow roots
and help prevent fungus. Make sure the mulch is kept away from the stem of the rose
bush to avoid rot.

## Fertilizing

Roses are heavy feeders that need balanced fertilizer to ensure strong, healthy 
growth and maximum bloom production. Fertilize in the spring when buds break open,
then at regular intervals during the summer and after each round of flowers. Reduce
application amounts with each occurrence to prevent over-fertilizing that can lead
to leggy growth and early frost damage in the fall.

Look for an organic all-purpose fertilizer with a balanced nitrogen-phosphorous-
potassium (N-P-K) analysis, such as horn shavings, Oscorna(r) rose fertilizer or
dried cattle manure, or a commercial fertilizer with a high concentration of phosphorous
and potassium, such as Super Bloom or Heirloom Roses(r). Some hobby gardeners use
coffee grounds or eggshells, which are both high in nutrients, to provide a natural,
inexpensive source of fertilizer.

Mulching is another important element in caring for a rose bush. A layer of mulch
helps retain soil moisture, minimizes weed competition and insulates the roots during
cold temperatures. Organic materials like shredded bark, rotted compost, straw or
well-rotted manure are excellent choices for mulching, as they enrich the soil as
they decompose.

If you’re growing roses in large pots, repot them each year, replacing the top inch
of potting mix with fresh, soil-based mixture such as John Innes No. 3. A light 
application of granular plant feed or a pelleted chicken manure is also beneficial.

## Pest Control

Roses are susceptible to several pests, including aphids, which chew slender stems
and buds, distorting leaves and stunting growth. They secrete a sticky liquid called
honeydew, which attracts ants and promotes the growth of black sooty mold. Spray
with a strong jet of water to hose off an infestation, or apply insecticidal soap
or low-toxicity synthetic insecticides. Be sure to also control the natural predators
that control aphids, such as birds and beetles.

Leafhoppers and nymphs use their piercing-sucking mouthparts to feed on rose foliage,
causing stippling spots that may merge to form white blotches on the leaf surface.
A severe infestation causes yellowing of leaves and stunted growth. Insecticidal
soap or horticultural oil can reduce populations of these pests.

Slugs leave ragged-edged holes in the center and margins of rose leaves, particularly
during wet growing seasons. Watch for a slimy coating on the leaves and flowers,
or look for slugs themselves at night when they are most active. Encourage natural
predators, such as slug-eating frogs and salamanders, to keep slugs in check, and
cover ground with a thick layer of mulch to prevent rot and provide a barrier for
the roots.

Sawfly larvae feed between the veins of leaves, and young ones resemble moth or 
butterfly caterpillars. A horticultural or neem oil spray or a weak solution of 
Bt (bacillus thuringiensis) is a good control. For a stronger application, try carbaryl(
Sevin), pyrethrins or spinosad, such as in Eight(r) Liquid Concentrate, Pyrethrins
and Captain Jack’s Deadbug Brew(r). Handpicking is possible when the infestation
is light.
