1. Choose two plants that have qualities you would like to combine in a new plant. First, remove the anthers from a newly opened flower with your fingers or a pair of tweezers, to create a seedbearing parent.
2. Take a flower from the other plant and rub its anthers on the stigma of the seedbearing parent. This plant will produce new fruit, so collect the seed to sow and raise your own, unique tomato variety next year.
