Tomatoes Not Setting Fruit on a Balcony: Pollination and Culture Fixes

Four tomato plants in a half-barrel on an east-facing balcony with mesh screening likely suffer from poor pollination (bees excluded) and overcrowding.

Immediate Actions

• Hand-pollinate: Gently shake flowers midday to transfer pollen.
• Thin to 2 plants max per half-barrel for root space.
• Water evenly: Consistent moisture—never bone dry or soggy.
• Stop overhead watering: Wet flowers don't pollinate; water soil only.
• One spray of seaweed extract to reduce blossom drop.
• Check light: East + mesh may = insufficient sun for tomatoes.

Next Year

Try a patio/determinate variety bred for containers—they fruit earlier and more reliably in limited space.
