- Costoluto Genovese Pomodoro Tomato Seeds, Heirloom NON-GMO, Low Acid, Indeterminate, Open-Pollinated, Productive, 80 days.
- Keep moist, not letting the seeds dry out between watering. **SOIL Temperature for Germination: 70-75F. Planting Depth: 1/4". Sprout tomato seeds in small containers, preferably 4" or smaller. In-ground germination is not recommended. Use a standard potting mix that is well drained.
- Start seeds in containers approximately 8 weeks prior to the planned set-out date. Plants should ultimately be transplanted to the garden 1-2 weeks after the expected date of last frost. Soil should be kept consistently warm, from 70-85F. Cool soils, below about 60-65F, even just at night, will significantly delay or inhibit germination. Additionally, overly warm soils, well above 90F, can inhibit germination and provide ideal conditions for seed rot.
- Over watering can cause fungal growth which leads to seed rot. Excess water can also bury seeds deep in the soil where they will not be able break the surface. Water when the soil surface just begins to dry.
- Multiple seeds can be planted in a single starter container, but should be thinned once seedlings appear so only a single plant remains. Seeds do not require light for germination but some light source should be provided for seedlings once they emerge from the soil.
Solanum lycoperscium - "The ugly tomato". The fluted, old Italian favorite that has been around since the early 19th century. Fruit are rather flattened and quite attractive with their deep ribbing. Once you’ve tried Costoluto you’ll never try anything else! This Italian heirloom is truly all-purpose. It makes intensely flavored slices with a scalloped shape. People also swear by it as the best flavored roasted, sauced or juiced variety. This variety has also became very popular with chefs. Good for home gardeners, market growers and chefs. Indeterminate. 80 days. HOW TO GROW: Once a few true leaves have developed, seedlings should be slowly moved outside (if sprouted indoors) to ambient light. Care should be taken not to expose seedlings to direct, scorching sun so plants may need to be hardened off via slow sun exposure. Hardening off can be done using a shaded or filtered light location, as well as protection from strong winds, rain or low humidity. Hardening off time varies, but can take 5-10 days. *** **SOIL Temperature for Germination: 70F **Plant Spacing: 24", **Hardiness: Zones 4-10 **Sun Requirement: Full Sun, **Days to Germination: 7-14 days under optimal conditions, **Germination Rate: 95%
