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.

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).

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.

I have grown them for 40+ years and I think it has to do with watering and weather. Better grown into/in the winter - a more even growing conditions - smaller variation of temp and water in the soil. If grown in the hotter weather they can dry out a bit and I think this makes them hotter. Try and grow quickly. Pick as soon as they reach the required size. They will keep in the fridge for weeks.
