Radish is a good crop because it can tolerate many conditions. They can tolerate frost conditions, they can even be grown in containers. While many novice gardeners like to start with tomatoes we think that radishes could be a better starting point.

About 250 varieties of radishes are known to gardeners. They can be found in many different sizes, colors and shapes, none of them available in markets.

How to plant your radishes


1.Spring radishes


Choose a place in your garden which gets at least six hours of sun per day and has a light, rich, well drained soils. The seed of the radishes are small and should be planted at about half an inch in a soil that has no large clumps. If they can be planted so close one to another they are perfect candidates for many intensive planting techniques.

Radishes mature in 20 to 40 days and disappear almost in the same amount of time so in you want to have them for a long period of time you should consider staggering your plantings. They germinate usually 3 to 10 days.


2.Long season radishes


Choose and prepare your place in the garden as you would for the spring radishes but till the soil to at least a foot. Plant the winter seeds at 3/4 inch deep for small varieties and 1/2 inches for larger ones but you should consult the seed package. You should start pulling your radishes as soon as they are large enough to use.


Insects and pests:

  • insect can sometimes infest the leaves but they will not effect the growth of the radish
  • root maggots can destroy the crops, if so you should consider choosing a different site for the next crop


A problem to grow radishes is the hot temperature, they don’t grow if the temperature in the air is over 75 degrees. If you are living where the summers are hot some shade will help,like an agriculture setting or planting on the east side of the house. They can tolerate the shade but they still need 6 hours of sun. They need just one inch of water a week and a slow release of organic fertilizer when you plant them is enough.

You will know when they are ready to harvest when they are at a usable size,don’t let them get too big because they won’t be so good to eat. The harvest period is usually about 1 to 2 weeks and can be saved up in the refrigerator for up to 2 weeks if they are stored properly.
