Can Alpines, Tomatoes, and Cucumbers Share a Greenhouse?

Alpines require cool temperatures, excellent drainage, and moderate light. Tomatoes and cucumbers thrive in warm, humid, high-light conditions. Combining them forces compromises that usually harm the alpines.

If attempted, place alpines on a shaded, well-ventilated bench with gritty soil, away from the hot, humid zone favored by tomatoes and cucumbers. A partitioned greenhouse or separate structures are strongly recommended.
