Vigorous, vegetative rootstock for large fruits and long-season cropping.
Grow tomato rootstock to add disease resistance and much improved plant vigor for an extended harvest. Maxifort adds a very high level of vigor. High resistance to Fusarium (races 1 and 2), Fusarium root rot, nematodes, corky root rot, tobacco mosaic virus, and Verticillium wilt. Disease resistance is not transferred to the scion plant. NOTE: Maxifort should be used for rootstock only. If left to grow on its own, the fruit produced is small, stays green, and is not good for consumption. Primed seed for improved germination. NOTE: With Maxifort, you may experience uneven germination in some conditions. Please refer to our tech sheet at the lower left of this page for detailed instructions on mitigating this issue. Avg. 21,200 seeds/oz.
SCIENTIFIC NAME: Solanum lycopersicum CULTURE: For more information on grafting with rootstock tomatoes, please refer to one of our production guides: Top Grafting Tomatoes or Side Grafting Tomatoes. Maxifort rootstock can lead to uneven germination in some conditions; if grafting to Maxifort, see our Maxifort production guide for tips on mitigating this issue. After cotyledons (first leaves) have expanded, fertilize with a complete nutrient solution (EC 1.0, pH 5.8) or equivalent as needed to keep plants dark green and healthy; increase EC as plants grow. Once the grafted plants have healed, continue by growing and managing the plants as you would normally. Grow plants at 66-68°F (19-20°C) day and night temperature. When transplanting into the greenhouse, maintain 73-77°F (23-25°C) day and night temperature for a few days after transplanting to promote rapid vegetative growth and root establishment. Once fruit begins to set, lower night temperature to 62-66°F (17-19°C) and keep a daytime temperature of 68-72°F (20-22°C). DISEASES AND PESTS: Regularly schedule releases of beneficial insects to control pests. TRANSPLANTS: Avg. 950 plants/1,000 seeds.

Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).
Disease Resistance Codes
Corky Root Rot
Fusarium Wilt (Races 1 & 2)
Fusarium Crown and Root Rot
Tobacco Mosaic Virus
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits. Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
Variety that we have found, based on our trials, to be the best performers in a climate-controlled greenhouse environment.
Variety that can be grown successfully using hydroponic growing methods, such as NFT (Nutrient Film Technique), DWC (Deep Water Culture), or other soilless growing systems.
