Cottonseed Meal on Blueberries: Organic + Synthetic Combo

Q: Cottonseed meal for blueberries—when/how much? Also use 10-10-10?

A: Organics release nutrients when soil warms; synthetics dissolve immediately (wasted if roots cold). Apply ¼" cottonseed meal in Feb, then ½ cup 10-10-10 per 100 sq ft in late March. Plants get 'breakfast' in March, 'big dinner' in April-May.
