10 Best Plants To Grow in a Greenhouse

Citrus Trees

Growing citrus trees to fruiting size can be difficult in short-season gardens, but they’re an ideal plant for a greenhouse with abundant sunshine and warm temperatures. Many citrus trees also bloom in winter, and the greenhouse protects these flowers from freezing.

• Grow citrus trees in pots or directly in the ground if your greenhouse has a specific in-ground planting area.
• Start with small trees from specialty nurseries like Logee’s Plants for Home and Garden. Note their mature size before placing your order.
• Fertilize citrus trees once a week with a soluble organic fertilizer.
• Citrus trees need a minimum temperature of 45 to 50 degrees, so your greenhouse will need supplemental heat in the winter.
