Conditions Required for Growth
This shrub needs well-drained soil, full sun, and moderate watering to grow properly. This shrub can survive in partial shade. Moderately fertile soil with pH ranging from 5.6-6.6 works well for them, but these can even grow in alkaline soils.
You could purchase the shrub from any nursery or garden center. You could also take a stem from a shrub and attach it to the ground using a U-shaped wire. Once it has rooted, you can replant it in your garden.
Getting rid of dead or diseased stems and branches is extremely important. Use pruning shears to remove these dead parts. Also, prune the areas where stems are crossing over each other. Prune the branches after the blooms fade. Cut the oldest branches back at the crown, but always remember that you must never prune more than one-thirds of the bush.
Apply a slow-release fertilizer in the spring. You must also be careful about the diseases that can affect this shrub. If the leaves are getting discolored, you must check for an aphid infestation. Aphids generally attack the tender branches and flower clusters. If the growth of the plant seems to be stunted and foliage looks yellow, it could be caused due to nematodes. Southern root knot nematodes can also cause a great deal of damage. Leaf spot fungi can also cause blotches on the leaves. Use pest control methods to avoid such problems.
