Radish
Raphanus sativus
The fastest-growing vegetable in the garden — a radish sown today can be on the salad plate in under a month. Crisp, peppery, and available in an extraordinary range of colours and shapes, they are perfect for filling gaps between slower-growing crops.

Successional Sowing
Sow little and often — every 2–3 weeks from March to September — as radishes run to seed very quickly in warm weather. A single large sowing is difficult to use before they become fibrous and hollow.Intercropping
Sow radishes as row markers for slower-germinating crops like parsnip and carrot, or in the gaps between brassicas and other slow-maturing plants.Summer Varieties
Winter radishes (such as daikon/mooli and Black Spanish) are sown in summer and autumn. They are much larger, milder, and store well.Soil: Any fertile, well-drained soil. Summer varieties need moisture-retentive ground.
