Eggplant Blossom Drop: Fix High Nitrogen and Overwatering

Large eggplants, spider mites controlled with oil. Prolific flowers but only one fruit; rest shrivel. You water every other day, used 15-9 fertilizer, switching to 15-15-15.

First Answer

Excess nitrogen → lush foliage, few fruits. Phosphorus critical for blooming. Switch to balanced fertilizer. Overwatering causes blossom drop; water deeply 1.5″/week (twice weekly). Water deeply to encourage deep roots.

Follow-Up: When to Apply Balanced Fertilizer?

High nitrogen applied 3 weeks ago. Use water-soluble 1-2-2 ratio (e.g., 10-20-20) or Miracle-Gro Bloom Booster / tomato-pepper fertilizer. Granular: every 6 weeks; water-soluble: every 2 weeks. Amend soil with organic matter (compost, aged manure, peat) each spring for sustained health.
