Question:

I got a hydrangea last summer. I have worked with the soil so that it changed to blue. The leaves are turning brown. Am I watering it too much or not enough?

Answer:

You're probably watering too little. Hydrangeas like a lot of water (the prefix hydro is Greek for water). Sometimes the tips or sides of a hydrangea's leaves will appear brown. This usually happens after it has suffered a dry spell or when it goes through a period where, for whatever reason, the roots were not absorbing moisture well and then the plant suddenly gets a good watering. When cells in the leave's tips suddenly take on water, they literally swell up and burst. What you're seeing with the brown tips is actually dead plant tissue where the cells burst.

This kind of browning can also happen to plants when they are initially transplanted and are suddenly given a heavy dose of water. Keeping your hydrangea consistently watered will prevent this from happening.

In general, over watering is usually followed by yellowing leaves that turn black at the edges. When under watered, leaves will droop and then turn brown.

Question:

My husband brought me a hydrangea bush, I am not sure what type, and it is curling and turning brown on the ends. We have gotten a few days of rain and I am not sure if that could effect this type of plant.

Answer:

It sounds as though your hydrangea may be suffering from a bit of transplant shock. I would just leave it alone for a bit and it should recover just fine.

This isn't all that uncommon, especially with potted plants that are transplanted in the garden and suddenly receive large doses of water. Your plant probably didn't received enough moisture at some point while in the pot at the nursery.

Once planted and exposed to a couple days of rain, the leaf cells probably become overwhelmed from the sudden change in moisture levels, which caused them to swell up and burst.

The brown tips indicate the cells that were destroyed. In a short time the leaves should toughen up and form a sort of "seal" that will prevent this from happening in the future. You can help by keeping your hydrangea watered on a consistant basis.

I Have a hydrangea tree (Pee Gee) and it's in partial to full sun. Only one side is blooming and the leaves are starting to turn brown and die. What can I do to revive my tree?

First, make sure your hydrangeas are in the right place. They should be in an area that isn't full sun. In Texas, we always grow them on the north side of a house in either partial sun or shade. If that's it, how often are you watering? Is the soil moist or dry before you re-water? (06/12/2010)
