If you grow them at home it’s easy to save your own seed for sowing the following season.
Tomatoes are generally self-pollinating – the flowers pollinate themselves before they open fully – so you don’t have to worry too much about keeping the variety pure. There is a small chance of cross-pollination by insects sneaking into the flowers early, so if you grow more than one variety it’s best to separate them with a tall crop, or plant them about ten metres apart.
There are a few simple steps for saving and storing tomato seeds for next season.
Choose the best early fruit from the strongest plants to save your seed from.
