“What are the best tomato varieties for USDA Hardiness Zone 9a?” Question from Janet of Summerfield, Florida.
Answer: The best tomato varieties you grow will depend on the time of year in your Central-Florida location. You are lucky to have the luxury of being able to grow tomatoes almost year-round. For summer, grow very heat-tolerant varieties, and in your milder springs and falls pick fast-to-produce varieties tolerant of cooler conditions. Overall, choose tomatoes that are high yielding and disease resistant.

Two of the best heat-tolerant varieties include the large, red-fruited ‘Heatmaster‘, which can take the high heat of the South, and disease and heat-resistant ‘Heatwave II‘, which bears deep red tomatoes with good flavor.
Wherever you live, tomatoes need constant soil replenishment. Getting your soil and feeding regime right is so important. In general, tomatoes like fertile, well-drained soil that is high in organic matter and has a relatively neutral soil pH of around 6.0 to 6.8. If you are growing plants in the ground, amend your soil thoroughly with a quality amendment that’s high in organic matter, like OMRI Listed Black Gold Garden Compost Blend. Be sure to raise low soils, so they are well-drained. It is also essential to feed regularly with a fertilizer formulated for tomatoes and to keep plants evenly irrigated.
