Some plants prefer to start life directly in the soil. Others are happy to be moved from being sown in pots. There are benefits and risks for both approaches. I start some beans and corn in pots over heat in September or October. When I transplant them into the garden, I plant them in a grid at about 30cm spacing in both directions. I sow some bean and corn seeds in the soil at the same time. In theory I should get a succession of crops. In practice, there’s very little difference in the timing of the first picking from both. I interplant lettuce and other salad crops between my corn. The salad is over by the time the corn is big enough to compete with it. Everything gets wind protection and netting against the birds.
