Coreopsis Gray-Green Leaves: Fertilizer Residue

Coreopsis blooming beautifully but leaves gray-green (not deep green). Recently sprayed liquid fertilizer.

Cause

White residue from foliar fertilizer spray.

Fix

• Heavy watering of foliage to wash off.
• Future: apply fertilizer to soil, not leaves.
• Old foliage will grow out.
