Growing hydrangeas?
Question:i have a hydrangea that blooms purplish pink flowers does taht mean my soil is high in alkaline or aluminim?
Answers:
Acidic soil makes blue blooms, alkaline soil makes pink blooms...adding lime to the soil increases the alkaline, iron sulfate adds acid.
You probably should lower the ph, hydrangeas like acidic soil, I use an acidic fertilizer once or every other week.
