Blossom End Rot in Upside-Down Tomatoes: Water Management Only Option

Introduction

Blossom end rot (BER) in sealed upside-down planters limits treatment options.

BER = calcium deficiency + inconsistent watering. Lime can't be added to sealed planter.

Maintain consistent moisture—only action possible.

Remove blackened ends; rest of tomato is edible.

In upside-down planters with BER, water consistently and trim rotted portions.
