What makes radishes hot? My radishes this year are almost too hot to eat
Radishes get hot for a number of reasons. If they are too old they are hotter, and
if they were grown under low fertility or if they got too dry, and their growth was
not as fast as it should have been, then they turn hot. Our erratic weather conditions
may have something to do with it as well. Many early season vegetables bolted quickly
this season. .
I have had a small backyard garden (20x50 foot) for many years. I put compost and
fertilizer(10-20-10) on it every year. This last spring I put on some well composted
chicken manure and tilled it into the soil. I rotate the crops around in this space,
so as not to plant the same crop in the same space 2 years in a row. BUT, In the last
2 years, I have not been able to grow any radishes, turnips or similar root crops,
all they produce is green tops. What can I put into the soil to cure this problem?
I assume you have ample sunlight, because all vegetables need a minimum of 6-8 hours
of sunlight to produce. I think possibly the soil is too rich, putting loads of nitrogen
into the foliage, and not forming the roots. Try mixing some coarse sand into the
planting area, and using a 10-20-10 fertilizer. Make sure you plant in the cool season
(before April 15) and thin the seedlings to give them ample room to grow, and see
what happens this year.
I have a problem of big radish leaves and no radish under the ground. What is my problem?
A couple of things can cause this--too much nitrogen fertilizer--which puts all the
energy into foliage, or heavy soil. Add compost or a little sand into the soil at
planting to give them a light airy soil to grow in, and use a well balanced fertilizer
at planting and again six to eight weeks later. Also, make sure you have at least
6-8 hours of sunlight a day--otherwise they may not be getting enough energy to produce
