If the soil has been fed for a previous crop, no further improvement will be necessary. If not, top dress the soil with vegetable fertilizer at the rate of 70 gm per sq m (2oz per yd) and rake the soil backwards and forwards to make it fine and crumbly. Summer varieties should be sown in succession from early spring to early summer in drills 1.3 cm (J, in) deep and 15 cm (6 in) apart. Sow the seed sparingly to cut out the need for thinning. If overcrowding does take place, thin the seedlings to 2.5 cm (1 in) apart. Winter varieties should be sown from late midsummer to mid late-summer in drills 23 cm (9 in) apart and later thinned to 15 cm (6 in) apart. Plenty of water is required in dry spells as fast-growing radishes become unpleasantly woody if they experience a drought.

Pests and diseases

Flea beetles and root fly.

Harvesting

Lift summer varieties while they are still young and tender. Winter varieties can be left in the soil and lifted during winter as required, but it is better to lift them in late autumn and to store the roots in boxes of dry peat.

Then it will be sufficient to dig thoroughly in autumn or winter and dust the surface with superphosphate (3 oz. per square yard) and sulphate of potashContinue Reading
