I have brought my potted hydrangea into the greenhouse do I need to keep it watered

Question

My hydrangea is in it’s first year it is a pink mophead

Answer 1

If it continues to grow, and use water, then you will water it as the top two inches dry thoroughly. If this variety does go dormant in your greenhouse, then you will only water 1/4 of a cup once a month. Just enough to keep it alive during dormancy.

This will depend on the low temps in your greenhouse, as well as humidity along with other factors.
