Small, spicy tasting root vegetable usually round but some longer varieties. Available in a range of colours between red and white.

Very easy to grow. Good for a child's first garden as seedlings appear in two or three days. Sow between other vegetables as they will mark the rows until the slower germinating plants appear.

Wash well and remove leaves and roots.
Use raw in salads or on their own with bread and butter.

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.

What is the best region of the US to grow radishes? What region is Arkansas in? I haven't been able to find that on the Web nor a picture of the US divided into its' regions as I've seen on seeds pack backs.

NW third of Arkansas is zone 7, rest is 8. Type "USDA zone map" into a search engine (I used Google).

The greens of radishes are also edible. Eat raw when the leaves are small and tender. More mature greens before turning woody or the stem becoming hard and dark or before leaves start turning yellow can be steamed or boiled....A little lemon, salt, olive oil and you have some great tasting and healthy greens.Great over a bed of rice. Also good for juicing.

Is June too late to plant radishes in Kansas City, MO?

My radishes came out too small or not developed a full bulb/root at all. I used a peat based potting soil and compost + vermiculite also amended with fish/kelp emulsion. I am growing them in 6 inch deep flats with proper drainage holes. The variety is Cherry Belles, Rover, French Breakfast. Planted them in late summer for fall.

Sounds like your soil is too rich, probably in nitrogen.

My baby sprouts were devoured in my raised bed, despite using bird netting. No bugs visible. What could it be??? So bummed.

You may have to go out at night to see what eats them. Could be snails or worms etc. If you can buy it, try some veggie netting.
