Identify my black radishes

Black radish is a edible root vegetables with very branched flower stems up to 60 to 80 cm tall. Its leaves are hairy. Its taproot can measure up to 20 cm.

Sow my black radishes

Radishes like sunny areas where they will grow better, but they accept semi shade. They need a light and cool soil - of any type, provided it is sufficiently loosened! Sow this radish from May to September, in a loosened soil, rid of pebbles, by drawing furrows 2 centimeters deep, spaced 10 centimeters apart. Sow your pre-mixed seeds with sand to distribute them more efficiently, and to avoid thinning afterwards! Cover with fine potting soil - about 1 cm - and tamp well. Vary, from sowing to sowing, the sites: because these vegetables suffer to be grown always in the same place.

Mulch my black radishes

You can mulch with, for example, a very thin layer of dried grass cuttings: this will protect your radishes from being "beaten" by the rain and will limit the need for watering a little! Only mulch after your radishes have grown and never cover the plants: only mulch up to the "collar" — that is where the root ends and the stem starts. Water after mulching.

Water my black radishes

Radishes need a light but frequent watering. - it's the guarantee of a sweet taste! Be sure to keep the soil fresh from sowing to harvest, especially in summer. For once, you can go free: wet the leaves, it will chase flea beetles - also called garden chips - almost the only pest that has time to tackle the radish!

Thin out my black radishes

After emergence and if necessary, thin the plants, leaving only a small stout every 15 to 20 centimeters, to facilitate their development.

Harvesting my black radishes

Harvesting of black radish is preferably done before the first frosts, but can also be done throughout the winter. They are generally considered to be good to be harvested as soon as black radishes start to come out of the ground! Once harvested, let it "dry" outside for a few hours. Then keep the black radish in a dry, cool and airy place.
