Pollination Basics: Why Your Garden Needs Pollinators and How to Help

Most fruits and vegetables—tomatoes, squash, apples, berries, cucumbers, melons—require insect pollination to set fruit. Without pollinators, flowers bloom but produce nothing. Understanding the process helps you support it.

How Insect Pollination Works

Bees, butterflies, wasps, flies, and beetles visit flowers for nectar/pollen. Pollen grains stick to their bodies and transfer to the stigma of the next flower, fertilizing the ovary. The result: seeds and the fruit surrounding them.

What Disrupts Pollination

• Pesticides (kill pollinators directly or sublethally impair navigation).
• Overhead watering during peak foraging (morning/evening).
• Extreme weather (rain, wind, heat).
• Habitat loss (no nesting sites, no floral diversity).
• High balconies, greenhouses, indoor gardens—pollinators can’t reach.

Solutions

1. Stop insecticides. Use targeted biological controls (Bt, predatory insects) or accept minor damage.
2. Use drip irrigation. Keeps flowers dry and accessible.
3. Plant a pollinator garden. Native flowers, succession of blooms, nesting habitat.
4. Hand-pollinate. Small brush or cotton swab for tomatoes; male flower stamen for squash/cucumbers.

Pollination is a partnership. Nurture your pollinators, and they’ll nurture your harvest.
