It’s best to plant radish seeds directly in the garden so as not to disturb their roots
Directly sow seeds outdoors ½ to 1 inch deep and 1 inch apart in rows 12 inches apart.
As they germinate, thin the successful seedlings to about 2 inches (5 cm) apart, allowing more space for bigger varieties
Radish may be irrigated at 7 days interval during winter and 2 days interval during summer
Keep soil evenly moist but not waterlogged.
A drip irrigation system is a great way to achieve this.
Putting a thin layer of mulch around the radishes can help retain moisture in dry conditions.
Keep the radish beds moist, but not soaked.
Watering radishes frequently and evenly will result in quick growth;
if radishes grow too slowly, they will develop a hot, woody taste.
If the soil is too dry, radishes will bolt and become pithy and too pungent to eat. If too wet, the roots will split and rot.
Thin radishes to about 2 inches apart when the plants are a week old.
Crowded plants do not grow well.
Add compost to the radish bed as desired to help retain moisture
An overly rich soil will encourage lush foliage at the expense of crisp, tasty roots.
Radishes are vulnerable to several types of insect pests, including cutworm, aphids, flea beetles and root maggots.
Using organic pesticide and insecticide will keep insects away from the plants and will help prevent infestations.
Radishes will be ready to harvest quite rapidly, as soon as three weeks after planting for some varieties.
For most varieties, harvest when roots are approximately 1 inch in diameter at the soil surface. Pull one out and test it before harvesting the rest!
Do not leave radishes in the ground long after their mature stage; their condition will deteriorate quickly.
Cut the tops and the thin root tail off, 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.
