Don’t Forget to Keep Sowing | Growing Radishes, Carrots and Beets

Growing radishes is extremely easy and very rewarding, especially if you’re partial to that scrumptious tart taste these great vegetables.

One of the most important things to do for any vegetable garden is remembering to sow successional crops. Without this, you’ll get a glut of crops early on in the season and then be left with woody carrots, tart radishes and beet’s so hard not even boiling makes them edible. Sweet, young crops are what we want, and sowing little and often is crucial.

Okay, it’s easy to say this…but it’s always easy to forget this too. Especially when the sunshine comes out, the summer holidays beckon and watering chores take over.

But, in principal, try and sow a few new lines of radishes, carrots and beets every two weeks in June and July to give a long harvest. In many cases, you can push this sowing into August too, especially for radishes as they can mature in just 30 days. Carrots and beets need longer but if the season is unusually warm and extends well into autumn (as it has been here in the UK for many years), then it’s worth throwing out the growing guide and just taking a few cues from the world around you.

Growing radishes

Three week old rows of radishes – almost time for picking!


  • Radishes – Sow every two weeks throughout the summer. Many varieties mature in just 30 days, so make use of all those daylight hours.
  • Carrots – Sow every two weeks until mid-July. <- This is the date at which you’ll get a guaranteed last harvest BUT, the summer season is often extended into September, even October, so I’d keep sowing until the beginning of August and keep fingers crossed.
  • Beetroot – Sow every two weeks until mid-July. As with carrots, this date is just a guide and you can carry on sowing later. In addition, even if the beets don’t have time to fully mature, you’ll still get leafy greens to use.

Successional sowing is a key principal in gardening, and it’s especially important for root crops where harvests are limited by the number of plants you’re growing instead the number of flowers on a bean, for example. So, if there’s one thing you get up to this weekend, it should be to get out and quickly sow some more seeds. It only takes five minutes and you’ll ensure that your attempts at growing radishes, carrots and beets results in bumper harvests throughout the summer.
