If you already have a tomato plant, you can root it to propagate new plants in as little as one week.
The key to this trick is finding side shoots from your existing tomato plant, and to make sure you aren’t cutting from the main stem. Many farmers suggest pruning these shoots, which makes them easier to cut off.
Once you’ve cut the shoots off, put them in a vase of water. Leave the vase in a sunny spot (like a windowsill) for about a week, and you’ll soon see roots start to grow.
And just like that, your future tomatoes are ready to plant!
