Planting and Growing Guide for Radish (Raphanus sativas)
Description
Radish plants produce small, spicy and crunchy root vegetable that are usually round, but some varieties are elongated. Radishes also come in a range of colors between red and white. Radish is very easy to grow and can be harvested very quickly. Radish is a cool climate crop. Early maturing varieties usually grow best in early spring. Later-maturing varieties are available that can be planted for summer use. Winter radish varieties are sown in midsummer to late summer. These varieties grow slower than spring radishes. The winter radishes are larger and have a more pungent taste. In warm areas, plant in early spring for a late-spring harvest. Plant again in late summer for a fall (autumn) harvest. Radish are frost tender and therefore in cold areas plant seeds several weeks before the average date of the last frost in your area. Ideally, plant radish seeds directly into the garden so as not to disturb their roots. You can get an early start in deep seed trays, or 'jiffy' pots that are planted together with the seedlings into the garden. Radish have many versatile uses. Wash the bulbs well and remove the leaves and roots. They can be added to salads - either whole, sectioned or sliced. The washed young leaves and small red roots can use in salads and stir fry dishes. Plant large numbers so that the young plants can be harvested early.
Planting Guide
Seed Depth: Sow seed directly in the soil at a depth about 5-10 mm (1/4 to 1/2 inch) deep. Germination is quick and very reliable.
Space between plants: Thin the plants for a space between plants of about 5-10 cm (1-2 inches). Spacing between rows is about 20 cm (9 inches).
Harvest Time: Harvest in 5-7 weeks. Smaller radish and leaves can be continually harvested as part of the thinning process. Plant in batches every week or two to ensure continual harvest
Hints:
- Dig aged compost or well-rotted animal manure into the soil several weeks before sowing seeds.
- Water frequently but do not over-water as this tends to encourage the plants to add more leaves rather than developing bulbs. Surround young seedlings with a layer of mulch to impede weed growth and help to retain soil moisture.
- Weed well in the early stages until plants are established. A good covering of mulch helps. Feed regularly with liquid fertiliser
- Ensure the bulbs are flavorsome by growing the plants quickly and avoiding growth checks. Pick the bulbs when small.
- Radish grows best in full sun or partial shade.
- Radish do well in a range of soils with neutral to slightly acid pH (6.5 to 7.5)
