This variety is of the French Breakfast type, often grown in a greenhouse for out-of-season production. Radishes grow best in cooler weather and should be planted in early spring or autumn, when temperatures cool down. They prefer well-drained soil and tend to split if soil conditions remain saturated for long periods. Radishes should be harvested at the ideal size for each variety. If left to get too big, they become peppery and not so tasty. Once harvested, the tops should be removed for optimal storage. Radishes with the tops removed keep in the refrigerator for up to two weeks.

Sow every 2 weeks from March to May and again from August — in the heat of summer radishes turn fiery and bolt. Keep the soil constantly moist.

Harvest and use

Pick as soon as the roots reach size — overgrown ones turn hollow and woody.
