Blossom End Rot in Tomatoes Before Harvest

Seeing black or sunken spots at the bottom of your tomato fruits just before harvesting? That’s blossom end rot often linked to inconsistent water supply and poor calcium uptake.

Before harvest, focus on: • Maintain consistent soil moisture—avoid drought and overwatering. • Avoid excessive nitrogen fertilization. • Improve root-zone conditions for better calcium uptake. • Mulch to reduce moisture fluctuations. • Remove severely affected fruits and allow healthy fruits to develop.

Healthy roots + consistent moisture = better-quality tomatoes.
