Cross pollinating tomatoes
Get started by choosing two tomato plants that you want to combine. Firstly, use your fingers or clean tweezers to remove the anthers from a new flower.
Next, the flower from the other plant can be rubbed on the stigma of the flower where the anthers were removed from.
All going well, new fruit will be produced and then the following year when you have a new set of seeds to sow, there will be a unique tomato variety for you the next year.
