Tomato Seeds 'Gourmansun' F1 - 6 Seeds - Marshalls Garden

An F1 hybrid seed is created by cross-pollinating two specific parent varieties to produce a plant with improved traits like vigor, yield, or disease resistance. Seeds saved from F1 hybrid plants will not grow true to the parent plant.

While specific height varies with growing conditions, indeterminate tomato varieties like this typically require support (staking or caging) and can grow quite tall, often 5-7 feet or more.

No, because 'Gourmansun' is an F1 hybrid, seeds saved from the harvested fruit will not produce plants identical to the parent. For consistent results, new seeds should be purchased each season.

Full sun (6-8+ hours daily), well-draining soil, consistent watering, and adequate spacing are ideal. They benefit from fertile soil and support as they grow.

While large indeterminate varieties can be grown in large containers (at least 15-20 gallons), they require consistent watering and feeding. They often perform best when grown in the ground.

This refers to the plant's genetic ability to better withstand infection from the oomycete *Phytophthora infestans*, a common and destructive disease in tomato and potato crops, especially in damp conditions.

The product description specifies 6 seeds per packet.

Ensure seeds are kept consistently moist, at the correct temperature (70-80°F / 21-27°C), and are not sown too deep. Check expiration date on seed packet if applicable.

Provide more light, closer to the seedlings. Ensure adequate but not excessive watering. Check soil temperature.

While resistant, severe conditions can still affect plants. Improve air circulation by spacing plants appropriately. Remove affected leaves immediately. Avoid overhead watering late in the day.

Ensure plants receive adequate sunlight (6-8+ hours daily), consistent watering, and sufficient nutrients. Check for pollination issues or extreme temperatures.
