I have just tried the Radish leaves in an omelette and you are right. It is absolutely delicious! Thank you sharing that!

I started my radishes in seedling trays and when they started to bulge at the root I planted the between my tomatoes. With love and water I now have small cherry radishes about 2 weeks off being pulled.

Radish usually show up in 5-10 days. Maybe too much water? No need for water every day if the soil is wet enough to stay together in a lump if you squeeze it in your hand. Try some more seed and less watering.

Can you eat the leaves of radish? I don't fertilise but have poor root development. Probably too much nitrogen in the compost that I forked through before planting.

Does 1 seed produce 1 radish? Or does it grow in a bush? Only 1 person will be eating them and I don't want to grow too many.

1 seed produces 1 radish. We had lots of varieties last season.

in simple the answer is YES. raphanus sativus is actually the name of most of the radish family that we know are edible. I plant in rows approximately 175mm apart, and try to space your seeds roughly 25 mm (1 inch) apart and about 10mm deep in the soil. you will find sparkler cherry belle long scarlet and many others also have the raphanus sativus name

As a commercial grower of radish (primex), I always remember the advice given to me many years ago, that being to never fertilise radish. As radish is one of the fastest growing vegetables, too much fertiliser causes the leaves to outgrow the root. Long leaves have no shelf life, just look in your local supermarket. I actually apply a VERY light application of Nitrophoska Blue which gives the leaves a beautiful velvety texture. I pick the radish when they are the size of a ten cent piece and leaves about four inches long. One of the great pleasures of my life is washing the bunches of radish and packing them in boxes of thirty for sale knowing that some-one is going to enjoy eating them as much as I enjoy growing them.
