Answer: As with so many of the heirloom tomatoes, Mr. Stripey has a long time to harvest after transplanting, roughly 90 days. As long as the plants seem healthy and are blooming, there is not too much more you can do. Pollination can be affected by nights that are too hot or too cold, days that are too hot, excessive rain, and so on. To try to increase fruit set you could shake the plants once or twice a day to assist with pollination, but generally speaking it is a matter of patience and cooperative weather.
