Fertilizing Hydrangea With Schultz
I have used Schultz fertilizer for decades and have converted many people who were using other fertilizers. I just love how my plants flourish and blossom when I use it. I have started to grow hydrangeas and want to be sure Schultz is a safe fertilizer to use on them as well.

This should be fine. For newly planted shrubs, however, I would use the fertilizer at half strength until the plants become more established.
