Gardening - Radishes
There are several different types of radishes.  They come in different
sizes and shapes, but most importantly, they come in varying levels of
heat.  This should be taken into consideration whenever you are trying
to choose the right radish to grow in your garden.
Much like the beet, these prefer cooler weather and it is always best to
plant from seed when you plant these.  I also transplant the plants I
take out to thin my radishes into another row.  A very good way to
control pests and disease in your plants is to avoid overcrowding.  You
can plant every couple of weeks early in the year and then late in the
year to keep a steady crop of radishes on hand.  Plant these in loose
soil and in full sun.  Just like with the beets, keep these root crops
moist so if a dry spell comes along, your radishes won't have a
tendency to split on you.  Also, if you overcrowd your radishes or let
them get to dry, they can go to seed without forming any kind of
radish for you.

Fertilize right before you plant.  You can use a liquid fertilizer or make a
tea of organic fertilizer to soak in right before you plant your seeds.  I
would then fertilize every few weeks until the radishes are ready to be
picked.  Root borers can cause you a problem on radishes.  You may
have to resort to some sort of insecticide to combat these if you have
had a problem with them in the past.
