Succession sowing is a way to make use of available, open space in the garden throughout the season. As one crop finishes producing, you can plant another crop in its place.
A great example of this in July is garlic. Once the lower leaves on the garlic stalk begin to brown, you can dig up the whole plant for harvesting. Be careful not to dig too close to the garlic bulb — you do not want to risk slicing it with the shovel’s blade. I let the soil around the roots dry and then I shake it off before hanging and storing them in a cool, dry place to cure.
