Extremely vigorous and disease-resistant rootstock.
When grafted to greenhouse-type and other indeterminate tomatoes, Colossus has the potential to greatly boost yield and vigor. High resistance to a broad range of soil-borne diseases keeps plants healthy. Higher yielding than Emperador, which it replaces. For use as rootstock only. Avg. 300,000 seeds/lb.

Growing Information:
Tomatoes
CULTURE: Much of the acreage of fresh tomatoes in Europe and Asia is grown in controlled-environment greenhouses or informal poly tunnels. Selected varieties enable growers to stretch the harvest season on both ends. Even unheated poly tunnels can ripen tomatoes 3 to 4 weeks earlier than outdoors. We trial varieties from many talented breeders to determine which are best adapted to low-tech systems. All are indeterminate, and must be pruned (1 or 2 main stems) and staked/trellised.
PACKET: 15 seeds, unless otherwise noted.
