planting soil for acer rubrum 'october glory'
I would like to plant a red maple 'October Glory' this fall, and know they need fairly acidic soil (compared to japanese maples, for example). I've read about a range of PH 4.5 - 5.0.
Can anyone recommend the type of soil to use, the size of the hole and future treatment for keeping the soil acidic?
For instance, could a soil (and treatment) similar to that for rhododendrons do? Are there products, treatments recommended for the years following the transplant?
