Growing notes

Eggplant needs consistent, even moisture — about 1 to 2 inches of water a week, more in heat. Deep, infrequent soakings that wet the whole root zone beat frequent light sprinkles, which keep roots shallow. Let the top inch of soil dry between waterings, but never let plants wilt: drought stress causes bitter fruit, blossom drop, and blossom-end rot. Water at the base early in the day and keep foliage dry to discourage disease. A 2–3 inch mulch of straw or shredded leaves is your best friend here, holding warmth and moisture between waterings.
