Radishes
The humble Radish is an incredibly easy vegetable to grow, as they tolerate most soil types and are quick to crop (usually within three weeks). They're delicious eaten raw, offering a fiery burst of flavour to salads. There's a wide variety of cultivars to choose from too, ranging from near spherical red-and-white roots, to long, thin white radishes, also known as mooli.
Radish
Because radishes are so quick to crop, don't sow all the seeds in one go, but at weekly intervals, for a successional crop through summer. A member of the cruciferous family, which also include Brussels Sprouts, cabbages, and cauliflowers and as such contain sulphurous componds which have been linked to protection from certain types of cancer.

When to sow
Summer Radish
- Sow Indoors: January & February
- Sow Under Cover: March
- Sow Outdoors: April to September
Winter Radish
- Sow Ourdoors: July & August
How to Sow Radishes.
- Sow March through to September in a well prepared bed of fine tilth.
- Sowings should be made about 2.5cm (1 inch) apart and 1cm (1/2in) deep to avoid the need to thin out.
- Should you need to thin seedlings out this should be done as soon as possible.
- Winter cultivars should be thinned to 15cm (6in) apart.
- Keep the soil moist to ensure rapid growth, and to keep the roots fleshy and tasty & prevent splitting.
Because radishes are quick to mature they can be used as a 'catch crop' being sown between rows of slower-growing vegetables such as peas and potatoes. A clever idea is to use the radish as a ediable crop marker for slow-germinating crops, such as parsnips and onion as the radish germinate quickly, marking out the row where other crops have been sown and can be pulled before interence with the main crop.

Tips for Harvesting
- Radishes need to be grown steadily and harvested young to ensure they remain succulent, otherwise they can become woody and inedible.
- Pull summer radishes as required, making sure they are never left to mature and become woody.
- Winter cultivars can be left in the ground and dug up as required, or lifted in November and stored.

Flea Bettle Close Up
The Flea Beetle
Attacks by flea beetle cause lots of tiny holes in the leaves.
Remedy:
The damage is only superficial, so usually not worth worrying about. If it is a particular problem in your garden you can cover the seedlings with horticultural fleece.
Slugs and Snails
Slugs and snails:
Feed on the young seedlings. You’ll see the tell-tale slime trail of slugs and snails on the soil around your crop, as well as on the leaves.
Remedy:
There are many ways to control slugs and snails, including beer traps, sawdust or eggshell barriers and copper tape. Slug pellets of powders based on aluminium sulphate or ferric phosphate are less toxic for wildlife.
Brassica Downy Mildew
Brassica Downy Mildew:
This is a common disease of brassicas, but less so on radishes, as they are not in the ground so long. The leaves will turn yellow, with white, fuzzy patches on the undersides. The radish root may also turn brown.
Remedy:
Remove infected plants as soon as you see them. Don’t plant radishes in the same place as previous brassica crops. There is no chemical control.
