When should I start to fertilize?
I have a Coral Bark, Bloodgood, and Emporer One Japanese Maples. All in the 5-6 foot range. I live in Oklahoma City and the buds will start to pop around the last week of March. When should I start adding fertilizer to the soil (I just use Mircle Grow)? Also, should I keep fertilizing every 2 weeks or so throughout the spring and summer season? I want to have some beautiful Jap Maples. Thanks.
