tips for growing radishes?

Christine, you can probably eat them without harm (they're a brassica), but the leaves are usually covered in prickly hairs, so why you'd want to is the main question - I would rather just eat the radish. You can certainly eat turnip and beetroot leaves, so radish leaves might be ok cooked? Perhaps you can let us know how you go with them?

Can you eat the leaves of radish e.g. in salad or cooked

Rex, I've found lack of water at any stage during growth will make radish turn bitter. It's also a dreadful problem with cucumbers - one day of wilting makes them completely inedible!

Could I please know why my radishes are so bitter? Last year tasted nice!

Long Scarlet radishes are good in a stirfry. All radishes make a great pickle.

Radish will mark the row next door if planted next to some other seeds that come up in more days than radishes. For example if you plant __?__ veggie that comes up in 10 days, next to a row of radishes, the radishes will come up certainly by day 2 ( all things present as to sunlight and water). That mean the ?? veggie will be along side and in next row but not until day 10. That way you know not to plant something else in row space next to radishes. Neat trick I never thought of. Wish I had marked my lettuce groups with one radish seed in middle.
