Question
I used to grow radishes when I was in the 8th grade in north Texas. Now I can't seem to grow any thing except the leaves. Everytime I plant all I get is leaves. The roots are long and red, but never fill out to form the raddish. I have changed soil and left more space but always the same results. I thought anybody could grow radishes but not me, I guess.
Any suggestions
Thanks

Answer
Jim, radishes are root crops that require cooler temperatures to grow and require a soil composed primarily of potassium. They also need soil that is friable to a depth of 6". They do not grow well in clay.

You can certainly amend your soil with organic matter and build it up to the proper depth much like you would with a raised bed. Organic matter would include compost, aged manure, and peat moss. You also should till in an granular fertilizer high in potassium. Potassium is the third number on the front of fertilizer bags. Avoid fertilizers high in nitrogen (the first number), since these promote lush floiage at the expense of large roots.

I hope this answered your question. Please write again if I can ever provide assistance.
