I have had good luck growing these from seed directly in the soil with the bottom of a milk jug cut out and placed over the prepared seed area to form a little greenhouse effect. They were somewhat slow to produce fruit but once the heat came on and other tomato plants were starting to fizzle out these took off and produced incredibly healthy plants with bunches and bunches of tomatoes right up til frost. I'm in zone 7 in Georgia so our summer heat makes it difficult at times to grow food crops. This past year, 2019, we had no rain for six weeks from labor day to the middle of October. We also had temperatures in the mid 90's during this time. This plant survived and produced fruit even without water. When the rain came again, the plant took off with continued healthy growth and a good supply of fruits. I will continue to grow this hearty plant.
