The radish (Raphanus sativus) is an edible root vegetable of the Brassicaceae family that was domesticated in Europe in pre-Roman times. They are grown and consumed throughout the world. Radishes have numerous varieties, varying in size, colour and duration of required cultivation time.
There are some radishes that are grown for their seeds; oilseed radishes are grown, as the name implies, for oil production. Radish can sprout from seed to small plant in as little as 3 days. Also known as spring radishes, summer radishes, winter radishes, Oriental radishes, Daikon, Japanese radishes, Chinese radishes, Raphanus sativus.

Watering
Water your radishes regularly during dry weather. Try to keep the soil moist. Give them a good long soak as soon as the top of the soil dries out. Avoid over-watering. The soil should never be soggy. If roots are left to sit in too much water they are prone to rot.
Soil
Requires well-drained soil, loose soil, high in organic matter, free from stones, with pH 5.8 to 6.8. Needs plentiful, consistent moisture.
Temperature
Germination temperature: 55 F to 85 F
Fertilizer
radishes should not need much feeding if planted in fertile soil. However, they may benefit from a dressing of compost tea a couple of times throughout the growing season. Avoid fertilizers that are high in nitrogen. They help to produce lush leaves but poor vegetables.
Harvest Season
Radishes will be ready to harvest quite rapidly, as three weeks after planting for some varieties.
Do not leave in the ground long after the mature stage, their condition will deteriorate quickly.
Cut the tops off short, wash the radishes and dry them thoroughly. Store in plastic bags in the refrigerator.
Radish greens can be stored separately for up to three days.
