Bloom Boosters are a good choice as they help encourage more flowers. I like to use a organic fertilizer that I make myself with things like kelp meal, bone meal and compost. As for watering, white hydrangeas like to have moist, but not soggy, soil. I water my plants every other day or so, depending on the weather. In the hotter months, I may water them every day.
