Rio Grande Determinate Tomato Seeds

Rio Grande Tomato Seeds | Determinate Variety, Meaty Fruits, Ideal for Hot Climates
Solanum lycopersicum
Listing is for 1 packet of 15 seeds

The Rio Grande determinate tomato is a reliable and heat-tolerant variety that thrives even in challenging garden conditions, making it an excellent choice for warm or tropical climates. Known for its thick, meaty flesh and balanced flavor, this tomato produces large, plum-shaped fruits that are perfect for sauces, salsas, and canning. Compact, uniform plants yield abundantly in a concentrated harvest window, allowing you to preserve or cook with plenty of tomatoes at once. The fruits hold up beautifully when cooked, creating rich, velvety sauces without excess water. For best results, plant in full sun, provide consistent moisture, and add light staking for support as the fruits ripen. Expect a generous harvest in about 75–80 days from transplanting.

TOMATO CHARACTERISTICS

Average fruit size: plum, average is 4oz

Height/Fertilizing: height can vary as it depends on your growing conditions and care. I have a fertilizing regimen which definitely helps achieve this kind of growth but is not necessary. Adding small doses of an organic fertilizer every week has really helped me take my tomato growing to another level. Synthetic fertilizers can burn or damage plants if used too often. Therefore, I recommend organic fertilizers because they wont damage plants when used often. However, do what suits your garden and the products you like to use. 

This is my current fertilizing regimen: I start by fertilizing weekly with 1/8 cup of Espoma Tomato tone sprinkled at the base of each plant. Once the plants start to bloom, I start alternating the weeks. One week with the Espoma Tomato Tone and then the next week with this recipe: mix 1 cup of Azomite dust and 1/4 cup of Fox Farms Tiger Bloom liquid into a 5 gallon bucket of water and pour some at the base of each plant. 

PLANTING
Germination: 7-14 days. To speed up germination I recommend using a heat mat. 

Seed Sowing Depth: 1/8” deep 

Sowing: I highly recommend to start in pots in doors with a heat mat 6-8 weeks before your last frost date. If you gardening in Florida, we kind of have two opportunities to grow tomatoes per year. You can start them in doors around July 1st and transplant into the garden end of September for fall/winter harvest. Or you can start from seed in doors 6-8 weeks from your last frost date for spring harvest. 

Days to maturity: 80 days from transplanting into the garden
