Heatmaster holds its own in hot Southern gardens, where temperatures are frequently high. A determinate hybrid tomato, plants produce strongly oblong fruits perfect for halving or quartering into salads. Medium-size fruits typically ripen in roughly 75 days. Heatmaster performs well as a fall crop in warmer zones. Plants are resistant to alternaria stem canker (Aal), gray leaf spot (Ss), verticillium (V), fusarium (F), tomato mosaic virus (ToMV), and Southern root-knot nematode (Mi/Ma/Mj).

Some Bonnie Plants varieties may not be available in your local area, due to different variables in certain regions. Also, if any variety is a limited, regional variety it will be noted on the pertinent variety page.

Heatmaster Tomato is rated 4.6 out of 5 by 10.
Rated 2 out of 5 by from East Texas Location I was quite disappointed in this variety. Planted along with 2 other varieties, this variety did not yield well, and suffered severely from disease while the other two flourished. Taste was average, many others taste better. It won't be in my garden again.

Rated 5 out of 5 by from Great for Florida temperatures. It's producing a bunch. Firm and tasty. Best I've ever raised in a pot.: I planted the Heatmaster in a 18" high pot. It took off and has been producing great fruit for two months. The fruit is not quite baseball sized, but is firm, great color, and tasty. I've never had such a potted plant in Florida. No diseases, yet.

Rated 5 out of 5 by from Heatmaster was the first to bear.: We are in the desert southwest w/ temps up to 105. Of the several varieties we planted, the Heatmaster was the first to give us a ripe, baseball-sized tomato. The plant is surviving the heat and wind well and looks lush.

Rated 5 out of 5 by from Great tomato for hot weather: Found these last year at Home Depot and I hope they have them again. All my neighbors want to try them after tasting my tomatoes last year. I had so many I gave them to neighbors and still had enough for my own table and for making tomato sauce. A great find for hot weather gardening.

Rated 4 out of 5 by from Hydroponic Heatmasterss.: I planted these in a Ebb & Flow hydroponic system and in 4 1/2 weeks they were nearly 5 feet tall and producing fruit. The temps have been running around 110 with heat index and the plants seem to love it.

Rated 5 out of 5 by from My heat master far out grew my other tomatoes. I'm in Tennessee and am looking for them again. My yield was about 50 on one plant and delicious. Largest one's in the garden.

Rated 5 out of 5 by from Grew these last year, and while we had planted it in the worst part imaginable -and cooler too- we still got about 5 tomatoes (I know, I know). But they were wonderful and beautiful. I've seen these grown elsewhere (relatives nearby) and it's gorgeous when it is growing well and giving you a big harvest.. thus, my high ratings. We didn't plan accordingly, but I recommend growing them.
