Organic generative rootstock.
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 six months or less, in unheated hoophouses, or with small-fruited (less than 100 gm) varieties. Also pairs well with the French Heritage series. Good disease package for soil. 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. Organically grown. Packet: 100 seeds.
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.
Packet: 100 seeds.
