How do you stop tomato plants?

'Stopping' involves removing the main growing tip by cutting off the top of the plant a couple of leaves above the highest truss you want to keep. Your tomato plant will respond to this injustice by trying to produce more side shoots so you will need to be extra vigilant in removing them once you have removed the top.
