Growing Hydrangeas - Knowledgebase Question

Riverview, FL (Zone 9A)
Question by Wpatalta
June 23, 2007
I tired putting them in the ground, but they did not want to live. I then planted them in shollow pots to have them begin to grow and even a bloom on one of them, but not much bush size. My question would be: the type of soil and how much sun and water?

I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!

Hydrangeas love to be in bright shade and will really burn in the full sun. Give them a soil with plenty of organic matter (lots of compost) and keep them moist. They really pitch a fit when they get dry or if their soil gets soggy!

Fertilize them periodically from spring through summer. Most any balanced fertilizer will do, although products made for acid loving plants will likely give you the blooms you are looking for. You may need to acidify the soil if you want the blooms to be blue. Two cups of sulfur (mixed into the soil before planting) per 100 square feet should do the trick. If not, add another two cups to the soil surface and water in well.

Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
