So at our greenhouse we grow 50 different varieties of tomatoes. Slow turnover of plants leaves many sitting in the stock greenhouse for a longer than ideal period of time. Most of these plants will get thrown away, but some of the most popular varieties will be propagated and allowed to re-grow.
Many growers in the southern states propagate, or cut back, their tomatoes during the dog days of summer. This helps the plants survive the extreme heat, and produce a second harvest once the weather has cooled down in the fall.
In this video I demonstrate one way to prune back and root tomato cuttings, but there are very many!
Let me know how you root yours!
