How often should I water hydrangeas outside?

The hydrangea should be watered thoroughly at least 3 times a week. Always water the plant all the way around the container, not just in one place. Water should come out the bottom of the pot. Never let it sit in water which will cause the roots to rot away.

Should I prune my hydrangea tree?

How do you keep a hydrangea tree small?

Pinch out the growing tips of new wood hydrangeas when they are a few inches tall in early spring. The plant develops additional side shoots, which will be shorter with more, but smaller blooms. You can repeat the process through midspring as the plant grows, depending on how much smaller you want the plant to be.
