care of hydrangea bush
I have a hydrangea bush. It's the type type with big blooms that bloom on dead wood. This year, I only got one bloom on the whole bush. The leaves are green, but no blooms. Last year I had tons of blooms. I am also noticing that the bush is getting very large. I think I should cut it back this year. When and how should I cut back my hydrangea bush? Any tips you have would be very helpful. Thanks.

You may be lacking phosphorus. If there is a lack of phosphorus in the soil, plants will have little to no blooms. You can either use a phosphorus rich fertilizer or add some bone meal to the soil.
