Radish Overview

Radish is a quick and easy growing root vegetable with a bright red-purple colour and good flavour. The crisp, sweet flesh does not get pithy, and is very hardy, growing in most gardens. The bright colouring makes a colourful addition to any dish! Radishes are edible globular roots attached to thin stems and wavy green leaves. The flesh is tender-crisp, succulent and firm. Its flavour is mild, only slightly peppery with some sweet notes. Eaten fresh or cooked, they pair well with fennel, apple, cheeses such as feta and chèvre, butter, creamy based dressings, vinaigrettes, bacon, white fish, cucumbers, mild salad greens, cooked eggs, noodles such as soba and udon, citrus, cilantro, mint and tarragon.

Common problems with Radish

Pest populations can be reduced by using a row cover.

Radish Companion Plants

Radishes can be useful as companion plants for many other crops, probably because their pungent odour deters such insect pests as aphids, cucumber beetles, tomato hornworms, squash bugs, and ants. They can also function as a trap crop, luring insect pests away from the main crop. Cucumbers and radishes seem to thrive when grown in close association with each other, and radishes also grow well with chervil, lettuce, peas, and nasturtiums. However, they react adversely to growing in close association with hyssop

How to harvest Radish

Harvest 3-5 weeks after sowing. Pick radishes any time after the tuber has developed but they will be larger if left in the ground. The tuber should be visible through the soil or you can brush some of the soil from the radish top to check the tuber.

How to propagate Radish

Seed

Sow seeds in early spring to early summer, and again from late summer, 12-15 cm apart and 10-15 mm deep. Germination takes 4-10 days. continue sowing every second week to have continuous supply.
