Spacing Tomatoes in High Tunnels
Amy Ivy, Vegetable Specialist
Eastern New York Commercial Horticulture
Proper spacing is a common concern of high tunnel growers. More plants does not necessarily mean more yield. Determinate varieties are spaced and trained differently than indeterminates, and grafted plants need more room than non-grafted. A well-spaced planting allows room for the grower to move down the aisles for harvesting, training and scouting for pest and disease problems.
