Mulch plants to prevent rapid drying of the soil and water plants during extended dry periods. Do not overfertilize plants with excessive nitrogen or potassium. Excess amounts of these nutrients reduce the uptake of calcium in the plant. When plants are dark green, extra fertilizer should not be applied. Treatment of affected plants includes applying a calcium solution to prevent additional fruits from being damaged.
Premixed solutions are also available.
Mix 1 teaspoon of bleach in 1 gallon of water. Dip fruit into solution and rinse. Replenish bleach periodically as needed.
