In this series I’m compiling the quick and dirty info on growing specific vegetables. Just the basics. No fluff, no frills. When you’re sitting down in the late Winter, surrounded by seed catalogs, and your garden plan in front of you, you want a quick reference. How far apart can you plant? What pH do they need? How much water? What vegetables can you plant next to others? Which should you avoid?

This quick and dirty 30 second guide to Radishes¬†should help you answer all those questions quickly, without having to sort through article after article. I’ve always wanted a quick cheat sheet like this, so hopefully you’ll find it useful too!



I have a homesteading confession: I don’t like radishes. I don’t like any vegetable that smacks you right in the taste buds while you’re eating it. Like it doesn’t want to be eaten and is fighting back.

They’re an old homesteading staple, though, because they’re one of the first vegetables you can grow in the Spring and they’re very forgiving. They can handle sub-frost temperatures and don’t require much (if any) maintenance to grow. For that reason I like them, but they’re definitely not a high priority on my growing list.

If, unlike me, you love radishes, here’s what you need to know:

Soil pH



6 hours or less


1 inch per week

Planting Time

Direct sow every 2 weeks, starting 4 weeks before the last frost

Compatible With

Tomatoes, Peppers, Cucumbers, Peas, Lettuce, Beets, Melons

Avoid Planting With

Potatoes, Hyssop


Direct sow in a row, thin to every 2 inches


Low/no maintenance. Weed and water.

Harvesting Fruit

Harvest in 35-40 days. The older/bigger the radish, the stronger the flavor. If you like mild, harvest earlier, if you like spicy or are going to pickle them, harvest later.

Saving The Seeds

Harvest the seeds when the pods have dried and are browned. Pull up the entire plant and hang it to dry in a cool, dark place. Harvest the seeds from the pods.
