Estamino is a strong, generative rootstock that puts a high proportion of energy into fruit. Easier to balance than Maxifort. Especially useful for tomatoes in cultivation for less than six months, in unheated hoophouses, or with small-fruited (less than 100 gm) varieties. Also pairs well with Marnero, Margold, and Marbonne. High resistance to Fusarium wilt races 1, 2, and 3, Fusarium crown and root rot, leaf mold, nematodes, tomato mosaic virus, tomato spotted wilt virus, and Verticillium wilt. For use as rootstock only. Seed has been organically primed to improve germination. USDA Certified Organic. Avg. 21,400 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.

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.
