Cleveland asks about overwatering tomatoes in 13-inch clay pots. Yes—excess water causes calcium deficiency → blossom end rot. Water deeply (1+ inch) every 2 days during growing season. Clay pots dry faster—check daily. Mulch surface. Consistent moisture, not saturation.
Tip: clay pots breathe—roots get oxygen. But they heat up. Group pots for mutual shade. Use saucers to catch runoff, but don't let sit in water.
Feed with fish emulsion (nitrogen) and kelp (micros) weekly at half strength.
