How many seeds you plant will depend on the size of your garden and how much you like radishes. :0) Recommended spacing is to plant seeds about an inch apart, and then when they sprout, to thin them to about 2 or 3 inches apart. This is a general guideline for spring radishes (which are planted in early spring, and sometimes also in late summer/early fall). Winter types, which are larger, can even be thinned to about 4 or 5 inches apart (these are often planted in summer for a fall harvest, and take longer to mature). No matter what type you plant, you will see the leaves (also called tops or greens) grow above the soil while the swollen root will develop mostly below the soil. However, you may see the upper part of this root poking out above the soil. The swollen root may be round, or cylindrical like a carrot, depending on what type of radish you grow. For spring radishes, harvest as soon as it is mature; check the days to maturity on the seed packet for an idea; for spring radishes, usually they are ready when the roots are about 1 inch across or a little more. If left too long in the ground, they will get tough. Winter radishes can keep in the ground for a few weeks after they are mature, if the weather is cool (but harvest before frost). Hope this helps!
