Heatmaster Hybrid Tomato Seeds
Heatmaster Hybrid Tomato Seeds are bred for one job: thriving when summer turns brutal. This variety reliably sets deep red, globe-shaped fruits even when daytime temperatures soar into the mid 90s, making it a standout choice for hot, sunny gardens in the South and anywhere summers get long and intense. The 7–8 ounce tomatoes are smooth, firm, and full-flavored, with a classic garden taste that’s perfect for slicing onto sandwiches, burgers, and fresh summer salads.
Maturing in about 75 days, Heatmaster grows as a compact, determinate plant around 4 feet tall, making it easy to stake, cage, and manage in beds or larger containers. The variety carries an excellent disease resistance package, including Verticillium Wilt, Fusarium Wilt (Races 1 and 2), Alternaria Stem Canker, Stemphylium Gray Leaf Spot, and Tobacco Mosaic Virus. That combination of heat tolerance and strong genetics gives gardeners broad adaptability and reliable harvests, even when conditions are stacked against most tomatoes.
If your summers are hot, dry, humid, or all of the above, Heatmaster Hybrid Tomato Seeds are a smart, stress-free choice. Expect sturdy plants, solid yields, and flavorful slicers that keep coming when other varieties begin to fade.
