Semi-Determinate 55 days to harvest Solanum lycopersicum

We asked our friend Amadeus (of Swiss Biodynamic seed company Sativa) about an early, delicious and disease-resistant tomato; he smiled and said, “You know you ask for the Holy Grail?” (Ohhhh, we know!) “I don’t have the Holy Grail, but try Seiger.” We agree: Organic Seiger Tomato offers incredible amounts of delectable 4-ounce bright red fruits, early even in cool seasons and she produces for weeks after other varieties had succumbed to a number of diseases, including Late Blight, Early Blight and Septoria. Short of a Holy Grail, try Seiger. She is our favorite early slicing tomato for the Northeast.

    I live in a hot dry climate so I was not sure if Seiger was going to be a good choice. I’m really happy with the results. Super early, ripe fruit with great flavor. I will be planting at least 3 plants next year. No disease, compact plant, consistent fruit, sweet and juicy. Whats not to like! If it was indeterminate it would be perfect.

    Over the years, after growing several saladette size varieties in my zone 5 central NY location, I think this just might be “the Holy Grail”! The semi-determinate plants started great on heat in soil blocks, grew fast and strong (but not too tall for my hoop raised beds), no disease, super productive, and the tomato flavor is sublime! I will be growing this variety for years to come!

Organic Seiger Tomato

Planting Method: Transplant Only

When to sow: 6-8 weeks before last frost

Seed Depth: 1/8 inch      Days to Germination: 7-10 at 80°F (27°C)

Sowing and seedling care: Don’t start too early! Sow indoors 2 seeds/cell or soil block, & thin to 1. We recommend sowing on a heat mat at 80°F to emergence, 75°F after. Good light is essential: Younger, less stressed seedlings are healthier and more abundant than older, more stressed seedlings. Pot up to 3-4” pots when first true leaves, submerging 3/4 of the stem below soil.

When to transplant: Harden off & transplant outdoors after frost, again burying stem.

Trellis helpful. Water soil, not leaves. Prune lowest stem “suckers” as they emerge.

Transplant Spacing:  2.5 feet    Sun Needs: Full

Days to Harvest: 55

Harvest: Semi-determinate.
