About fertilizer, usually the plant does not need much added fertilizer. You can add some compost or manure to the soil around the base of the plant in early spring.

To keep your plant healthy and promote strong growth, it's important to pay attention to the roots. Be sure to plant hydrangeas in well-drained soil and water regularly. If the roots are too wet, they can rot. If they are too dry, the plant will wilt. If you're not sure if the roots are getting enough water, you can check by gently digging around the base of the plant. The roots should be white and healthy-looking, not yellow or brown.
Pruning your hydrangea paniculata limelight is an important part of keeping your plant healthy and looking its best. Pruning should be done in late winter or early spring, before new growth begins. You can prune away any dead or dying branches, as well as any branches that are crossing or rubbing against each other. You can also cut back the plant by a third or more to encourage new growth and produce fuller, bushier plants.
Propagation is best done in late summer or early fall by rooting stem cuttings. Cuttings should be taken from new growth that is still green and supple. Cuttings should be 6-8 inches long and have at least 2-3 leaves. Strip the leaves from the bottom half of the cutting and dip the cut end into rooting hormone. Place the cuttings in a well-drained potting mix and keep moist. Cuttings should root within 4-6 weeks.
Usually, the plant growth rate is between 12 and 24 inches per year. This plant can grow in sun or shade and prefers moist, well-drained soil. It blooms from July to September and its flowers are white or pale pink.
Common problems for this kind of plant are pests and diseases. The most common pest is the aphid, which can cause the leaves to yellow and the plant to stunted growth. Aphids can be controlled with insecticidal soap or horticultural oil. The most common disease is powdery mildew, which can cause the leaves to turn white and the plant to lose its leaves. Powdery mildew can be controlled with a fungicide.
