Plant techniques

Check a crop’s pollination needs

Identify the crop and cultivar: self-fertile, self-incompatible, separate male and female plants, and seedless fruiting types have different needs.

When to do it

Before buying fruit varieties and when flowers fail to produce a crop.

What you need

  • Species and cultivar names
  • Flowering observations

How to do it

  1. Identify the crop and cultivar: self-fertile, self-incompatible, separate male and female plants, and seedless fruiting types have different needs.
  2. For a crop needing another pollen source, confirm a compatible variety that flowers at the same time. Two plants of the same clone may not solve the problem.
  3. Watch for flowers, receptive stages and insect visits. Open covers where pollinators are needed and avoid harmful treatments during bloom.
  4. If fruit still fails, check heat, cold, moisture and plant maturity before assuming a pollen shortage. Use hand-pollination only where suitable for that crop.

What success looks like

  • Compatible pollen and receptive flowers can coincide.

Watch out for

  • Assuming every fruit needs two plants.
  • Hand-pollinating a cucumber variety that should set without it.
