Most hydrangeas are hardy, but late frosts can damage early growth. Cover new growth in early spring if frost is expected.

Watch for pests like:

Aphids

Spider mites

Slugs and snails

Treat infestations with insecticidal soap or natural predators like ladybugs. Diseases like powdery mildew and leaf spot can occur in humid conditions; ensure good airflow and avoid overhead watering.

Simple Tricks for Bigger Blooms
Here are a few final tricks to encourage abundant flowering:

Deadhead spent blooms regularly to redirect energy to new flowers.

Use Epsom salt (magnesium sulfate) once or twice during the growing season to support strong stems and vibrant color.

Rotate your plant slightly each year to ensure even sun exposure.

Keep soil consistently moist but not waterlogged for steady growth.

Give older plants a deep prune every 4–5 years to rejuvenate them.

Enjoying Your Hydrangeas
With proper care, hydrangeas will reward you with stunning blooms from late spring through fall. Whether you prefer soft blue clusters, bold pink mounds, or dramatic white cones, these flowering shrubs add beauty and charm to any garden space.

With these simple tricks and a little attention, growing hydrangeas becomes a rewarding and easy part of your garden routine.
