Winter Vegetable Gardening Indoors: Fresh Greens All Year

Cold weather doesn't end the harvest. Indoor winter gardens—pots on a sunny windowsill or a soil-filled grow box—keep vegetables coming through the dark months.

Two Approaches

Container method: Large pots for carrots, tomatoes, peppers. Grow box: 4×3 ft, 12+ inches deep, with drainage. Both need 4–6 hours sun (or grow lights), steady temps (65–75°F), and good airflow.

Sources and Timing

Transplant summer garden survivors, or start seeds in late summer for winter harvest. Microgreens yield in weeks. Research varieties bred for low light and cool temps.
