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, 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. Avg. 21,200 seeds/oz.
SCIENTIFIC NAME: Solanum lycopersicum CULTURE: For more information on grafting with rootstock tomatoes, please refer to one of our technical guides: Top Grafting Tomatoes or Side Grafting Tomatoes. 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. After cotyledon 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. 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). TRELLISING: It is recommended to prune the plants to 1-2 stems and trellis up a string. HARVEST: Fully vine-ripen fruit only for local retailing or use. Pick fruit less ripe the further the distance and the longer the time between harvest and the customer. DISEASES AND PESTS: Use crop rotation or new media to reduce soil-borne disease problems. 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
Fusarium Wilt (Races 1 & 2)
Fusarium Crown and Root Rot
Corky 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.
