When to Harvest Radishes

Radishes are ready to harvest once roots reach a usable size. Because radishes grow quickly, they are often harvested only a few weeks after planting.

In the UK, radishes can be harvested throughout the growing season depending on planting time.

Checking roots regularly helps you harvest before they become woody.

Signs radishes are ready to harvest

Radishes are usually ready when:

  • the root is visible at the soil surface

  • roots feel firm

  • plants are well established

Small to medium-sized roots usually taste best.

Harvesting radishes carefully

Pull radishes gently from the soil.

Loosen the soil first if needed.

Harvesting regularly helps maintain good root quality.

Harvesting container radishes

Radishes growing in containers can be harvested in the same way as garden-grown plants.
