Tomato, Greenhouse

Greenhouse Tomatoes

A mid- to late-spring and early summer crop seeded in January-February can be profitable for growers, especially those with a retail outlet for their crop. A fall crop, seeded in late June for harvest through October into early December. Keep in mind that a fall crop is less productive because of shorter days and, in spite of lower heating costs, the profitability of the crop remains questionable. However, some growers continue to manage a spring/summer crop into the fall if there is a strong market demand.
