The bushes seemed to make it through with no damage or breakage, but since then all but one has stopped growing, stopped showing new growth, no blooms, no ne buds and the leaves have mostly turned pale green, although some parts of each bush still have nice dark green leaves.

It can spread feet tall and wide so give it plenty of space.

The viburnum and the Japanese cypress wil give some structure for winter as will the ornamental grasses, which even if they die back their foliage can be interesting. If you want more green in the winter you could also just line the back of the bed next to the porch with low growing boxwood and allow them to grow together to form a hedge which would suit your traditional style home.

Like all roses, Knock Out varieties attract pests that interfere with growth and can prevent flowering. Soft-bodied insects include aphids, thrips and leafhoppers, which can cause leaves to yellow and drop and might distort flower buds, preventing them from opening.

Other common pests that can damage a bush and slow flower production include Japanese beetles, mites and hard-bodied insects called scale. Releasing beneficial insects, such as ladybugs, assassin bugs or parasitic wasps, can control leafhoppers, scale and other pests. Spraying with insecticidal soap, diluted at a rate of 6 tablespoons per gallon of water, destroys mites, thrips, aphids and other insects, while hand-picking or using beetle traps can control Japanese beetles.

Roses such as the Knock Out varieties are susceptible to fungal diseases that can destroy foliage, slow blooming and, in left uncontrolled, damage or destroy a plant. Powdery mildew causes fuzzy white spots on leaves, while black spot causes black spots on leaves, followed by yellowing and then leaf drop. To prevent these problems, follow good cultural practices such as planting roses where air circulation is good and watering only from a soaker hose or drip irrigator, keeping foliage dry.

If a plant has a fungal infection, prune off damaged stems and spray the bush every week or two with 1 teaspoon of baking soda per quart of water, with 1 drop of liquid soap added to help the spray adhere to foliage.

The Knock Out roses grow as compact, bushy shrubs that cover themselves in flowers from spring into early fall.
