Limelight Hydrangeas may occasionally face challenges from pests and diseases. Aphids and spider mites can appear on leaves and stems, while powdery mildew and leaf spot can affect foliage under humid conditions.Pests such as aphids, spider mites, and scale insects can weaken hydrangeas by feeding on their sap. Diseases like powdery mildew, bacterial wilt, and leaf spot can also significantly impact hydrangea health.Large Trees and Shrubs Large trees and even large shrubs can cause harm to hydrangeas and other plants, both by blocking incoming light and by outcompeting them and consuming all the available resources, Lenhart says. You should especially watch out for willow trees, McConnell says.Water your hydrangeas in the morning before the heat of the sun is strong enough to quickly evaporate soil moisture. Try to avoid watering at night, which can encourage mold and mildew as the moisture sits through the cool night. Water your hydrangeas through the growing season as well as in late fall.
What month do limelight hydrangeas bloom?
Depending on where you are in the country, the hydrangea will bloom from mid-summer all the way until late fall. The plant may bloom even earlier than that in warmer climates in zones 7, 8 and 9. When exposed to excessive sunlight, their leaves may scorch, turning brown or yellow, and delicate blooms can wilt or fade prematurely.

The reblooming Endless Summer® Hydrangea series prefers part shade.For instance, if you live in a hot, dry region, you might water a new hydrangea twice a week in the spring, but that could ramp up to daily during a brutal summer heatwave. In a cooler, wetter area, once a week might be perfect for both spring and summer, and even less during rainy stretches.
