Radishes just don’t get the spotlight they deserve. We mostly pop them in a salad or on a relish tray, but they can be prepared in so many more delicious ways! This lightning fast grower is a great addition to any garden, especially for the cook who is looking to broaden their radish recipe horizon.

Radishes love cool weather and grow best in spring or fall. Give them loose soil and lots of sun and they’ll mature in just about 25-50 days. They are one of the easiest and fastest veggies to grow, and are a great veggie to start with if you are a beginner gardener.

What You Need


  • Radish seeds
  • Compost
  • Garden markers


  • Garden tools


Radishes are fast growers, germination takes anywhere from 3-10 days. Since they thrive in colder temperatures and germinate so quickly there is really no need to start them indoors.

Prepare to plant the seeds by creating rows about 1/2″ deep and at least 12″ apart, mixing in at least 1″-2″ of organic compost. Mark the rows with a “Radish” garden marker.

Drop the seeds in the soil, spacing them at least 1″ apart.

Cover the seeds with 1/2″ soil and water evenly, be sure not to flood the rows -you don’t want your seeds floating away.

Once the radishes reach 2″ tall, thin them out if need be. Continue to water evenly, letting the water soak into the soil at least 1/4″ deep.

Don’t forget to weed regularly so your radishes receive as many nutrients from the soil as possible.

Once the plant leaves are 4″ long they are ready to harvest. The longer you leave a radish in the ground, the hotter they get and the more susceptible to rot they become, so harvesting earlier rather than later is recommended. Remove the radishes from the ground by pulling them straight up out of the ground by their leaves.

Enjoy them in salads, or other interesting dishes!
