Depending on where you live it varies when it's time to plant your young tomato plants. In the Nordic April/May and South of Europe you can do it already in March. Whenever you do - carefully accustom them to the sun, otherwise the leaves will burn easily. Plant your tomato plants in large pots and use our small spade. Don't forget to "steal" the tomato plant. You do this by removing the shoots that come in the leaf folds. These shoots otherwise steal a lot of energy and water from the plant at the expense of the tomato fruits.
