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.
