The scientific name of radish is 'Raphanus sativus' which belongs to the Brassicaceae family. The word 'radish' comes from the Latin word 'radix', meaning 'root', and the Greek word 'raphanus', which means 'quickly appearing'. That's why radishes are one of the fastest sprouters in the garden when they're planted from seed. Radishes are easy to grow. They are fast-growing and are ready to harvest in about four weeks from sowing. The key to successfully growing a great radish is to plant when the weather is cool, to not plant too close together and to harvest promptly before the roots get woody and bitter!

Radish Varieties


Radishes are classified by their shape or by their preferred growing season.
There are two basic types of radishes: spring varieties and winter varieties.
Which radishes you select to grow will be down to your own taste preferences. 
The spring varieties are so many; from "Cherry Belle", "Champion", to "Crimson Giant" they should be planted in early spring to mature quickly in cool weather for the best production and quality. Most spring radish varieties mature in less than a month.

The winter varieties are "China Rose" and "Long Black Spanish" they require a longer growing period but are superior to spring types in many ways. They hold their quality in the garden longer, store better, and have a more distinctive flavor. By growing a number of varieties from both types, you can be harvesting radishes throughout the spring, and again in the fall and winter.

Radishes are so easy to grow, and knowing when to harvest is the key to enjoy perfect radishes with crisp roots and mild flavor instead of hot as fire.

Radish seeds can be planted in the fall and in spring, but growing should be suspended in the summer, when temperatures are typically too hot. Hot temperatures may cause radishes to bolt. Otherwise, radishes are one of the easiest vegetables to grow.


Radish plants are primarily grown for their roots. The soil needs to be rich in organic matter, it can not be compacted. If the soil is more clay-like, mix in some sand to loosen it and improve the drainage.

 Radish Plants Care


Radishes require little care after planting, but they must have sufficient and consistent water for best quality.
  • Remove any weeds growing around your radishes and keep the soil moist. 
  • Radishes require several hours of direct sunlight each day for the bulb to fully develop.

 Harvesting Radishes 


Radishes can be harvested by pulling or by gently loosening the surrounding soil. Once harvested, remove the green tops to prevent them from drawing moisture and nutrients from the bulb.


Because radishes mature so quickly, do not leave them in the ground long after their mature stage. Spring radishes should be checked frequently as they mature. The reason many gardeners fail with radishes is that they leave them in the ground too long. Radishes will be ready to harvest quite rapidly, as soon as three weeks after planting for many varieties. 
When you see the top portion of the radish poking up through the soil, and when it's almost an inch across, it's ready to harvest. Radishes can be harvested by pulling or by gently loosening the surrounding soil. Once harvested, remove the green tops to prevent them from drawing moisture and nutrients from the bulb.

To collect the seeds, let radishes plants grow flowers. Those will mature into seed pods. Stake up the stems so they don’t fall over and burst. As seed heads mature, cover them with lightweight cloth bags so that birds don’t eat all the seeds. When the seed pods dry, bring indoors and store in a dry place until the next growing season.
