Boron for Watermelons: Soil Drench Method Using Household Borax

Boron Deficiency Mimics Pollination Failure

Before treating, confirm honeybees are active. Poor pollination looks identical to boron deficiency.

Safe Soil Application

Mix 1 tablespoon 20 Mule Team Borax in 1 quart water. Dribble along a 100-ft row. Do not exceed this rate.

Critical Warnings

• Boron toxicity is irreversible—hard to leach from soil.
• Foliar spray risks leaf burn—soil drench is safer.
• Borax ≠ boric acid—different compounds.
