Simple tips on when to harvest radishes
Radishes are one of the easiest vegetables to grow from seed. They germinate quickly and are ready to eat in just a few weeks after they've been planted, making them a great addition to your raised garden bed ideas.
But what if you can’t wait for that peppery crunch? Rachel Morgan, horticulturist at You Garden, suggests being a little cautious with harvesting all your radishes at once. 'Before you lift your whole crop, check the size of your radishes,' Rachel says. 'You can do this by removing just the top layer of soil around one of the plants in the row.'
'Radishes are ready to harvest once they've grown to about an inch (2.5cm) in diameter. If you are happy that the size is correct, pull, wash and eat fresh, when crunchy and delicious.'
Harvest summer radishes by taking hold of the top growth and gently easing them out with a fork or trowel. Eat them soon after harvesting for maximum freshness and crunch.
Winter radishes can be left in the ground and dug up as required, or lifted in late fall and stored.

How do you store radishes after harvesting?
Now you know when to harvest radishes, you'll want to make sure you keep them fresh for as long as possible. Once you've harvested your radishes, you can place them in a container, seal it and put it in the refrigerator. Radishes will stay fresher for longer when kept cold – usually for about a week.
Before storing your radishes away, it's also a good idea to trim off the greens, as they're edible too.

What happens if you pick radishes too late?
If left to grow too large, radishes can become woody and inedible. Increasingly warm temperatures can lead to the plant bolting too. That's why it's a good idea to stay on top of your harvesting and get your radishes out of the ground while they're still young.

Radish greens are both edible and delicious in salads
Can you eat the radish greens and leaves once harvested?
When it comes to picking for the pot, remember radish greens are edible in their entirety. Their texture is coarse though, so they don’t work well in salads unless they’re baby leaves.
