Do hydrangeas need pest control? This is among the common questions most Utah gardeners who love the beautiful blooming shrubs will be asking. Although generally hardy, hydrangeas can fall prey to many pests that can affect their health and beauty. Understanding proper pest management and hydrangeas care is extremely important to ensure these beautiful flowers will last in your Utah garden. From recognizing the most common insects to effective means of control, this comprehensive guide will help protect your hydrangeas and maintain their growth through the growing season, especially in Utah’s diverse climate zones.
What Are Hydrangeas Plants?
Hydrangeas are flowering shrubs famous for their large, colourful blooms that fill many of Utah’s gardens starting from late spring to fall. These unlimited varieties can produce colors ranging from pink to blue, white to purple depending on various pH levels and growing regions. The ability to adapt to a variety of growing conditions generally makes the plant as popular with the novice gardener as with the seasoned veteran. The most successful varieties in Utah’s climate include the Bigleaf (Hydrangea macrophylla), Panicle (Hydrangea paniculata), and Smooth hydrangeas (Hydrangea arborescens).
Why Hydrangeas Attract Pests
Like many ornamental plants, hydrangeas make for frequent hosts of pests because of a variety of reasons. Their juicy stems, succulent leaves, and non-inhibiting pollen stand as lures for a multitude of insect species. The tissues are saturated with moisture, thus enticing sap-sucking insects during periods of rapid growing. Knowledge of the plant’s attraction to insects will greatly enhance any effective attempts against these disturbances. Pests can hide among the dense foliage of the plant. It should also be noted that early detection is crucial to counter pests. So if you are wondering Do hydrangeas need pest control? Then the answer would be yes.

Common Pests for Hydrangeas

1 Spider Mites: Tiny little arachnids that cause stippling on leaves and leave very fine webbing. They thrive in the hot and dry conditions common to Utah.
2 Aphids: Small, sap-sucking insects that occur in clusters on new growth and might cause curling leaf deformities. The honeydew they excrete can lead to sooty mould.

4 Scale Insects: Immobile but sucking pest that attaches to stems and leaves and sucks plant sap, leaving the leaves yellow.
5 Rose Chafers: These beetles attack flowers during the bloom season, damaging buds and open blooms alike.
6 Leaf Rollers: These caterpillars roll leaves into a safe shelter while feeding on leaf tissue.
