What's wrong with my hydrangea leaves?

What do Overwatered hydrangeas look like?

Visible Symptoms

If by chance you do overwater your hydrangeas, the symptoms will look strikingly similar to underwatering. The plant will start to wilt, most often starting at the lower leaves closest to the ground. Leaves may start to yellow and fall off as well.

Should I cut off Brown hydrangea leaves?

Prune off the ugliest leaves, and adjust your irrigation to keep water off the leaves. When you see leaves with brown or yellowish spots, it could be anthracnose, a much worse issue because it can kill the shrub.

What does a diseased hydrangea look like?

Leaf Spots (Cercospora species and Phyllosticta hydrangea)

Cercospora manifests as circular purple or brown spots on the bottom of the plant. As the lesions get larger, the leaves can turn yellow and fall off the plant. Watering without getting the leaves wet will help to prevent these diseases.

Why does my hydrangea have black leaves?

Hydrangeas love water, but excessive irrigation or wet foliage injures plants. Insufficient water causes leaves to turn black or brown. Severe drought conditions cause entire plants to defoliate. Too much water at the root zone, combined with a poorly draining site, causes root rot that promotes black spots on leaves.

How do I know if my hydrangea is dying?

Re-pot your hydrangea in a pot of fresh, dry soil and make sure you do not overwater your plant if indoors. Yellow, floppy leaves mean you are overwatering your hydrangea, and wilted leaves are usually a sign of root rot.

How often should hydrangeas be watered?

Water at a rate of 1 inch per week throughout the growing season. Deeply water 3 times a week to encourage root growth. Bigleaf and smooth hydrangeas require more water, but all varieties benefit from consistent moisture. Use a soaker hose to water deeply and keep moisture off the flowers and leaves.

Can hydrangeas get too much water?

One reason hydrangeas get over-watered is when they wilt in the afternoon sun. Our gut reaction is to run out and douse the plant in water, but STOP! That's not always the best option. Over-watering can actually prohibit future bloom production.

Why are the edges of my hydrangea leaves turning brown?

When one observes yellowing and browning leaf edges and leaf tips a day or two after the plant has been fertilized, the roots may have been burned. Aluminum sulfate, which is sometimes added to the soil to change the color of hydrangea blooms, also can cause root damage if applied too liberally.

What happens if you don't deadhead hydrangeas?

No need to worry – this is simply a sign that it's time to remove the flowers, a process called deadheading. When you deadhead hydrangeas, you aren't harming the plants at all. Removing the spent blooms triggers flowering shrubs to stop producing seeds and instead put their energy toward root and foliage development.

What does anthracnose look like?

What does anthracnose look like? Symptoms of anthracnose vary from host to host, but in general, include irregular spots, and dead areas on leaves that often follow the veins of the leaves. Affected tissue can vary in color, but is often tan or brown. Severely affected leaves often curl and may fall off.

Why are my hydrangea leaves turning purple?
