James martin shares the key to growing tomato plants on this morning

However, the chef then revealed the key to making sure your tomato plants are a success.  Taking the camera over to the much taller tomato plants in his greenhouse, James said the key is to

make sure they grow upright.  To do this you need to remove the shoots that come off the central stem at the top; this helps to force the plant upwards so that it continues to grow.  He also

warned gardeners to avoid knocking off the flower buds, as wherever there is a flower, a tomato will soon grow.  Walking around his garden, the Saturday Kitchen star also recommended

growing mint separately from other herbs in a pot as it “goes crazy” and takes over the patch if it’s mixed with others.
