Does basil grow well indoors?

When you accurately mimic its Mediterranean habitat, basil grows best indoors. I've had productive plants through winters in Chicago by paying attention to details. Achieving success requires good light, warmth, and healthy soil nutrients throughout the seasons.

Light Essentials

  • Minimum 5-6 hours direct sunlight daily
  • LED grow lights supplement winter darkness
  • 14-hour light cycles maintain growth rhythm
  • Rotate plants for even exposure

Soil & Nutrition

  • Well-draining mix refreshed annually
  • Monthly fertilization during active growth
  • Balanced 1-1-1 NPK formula preferred
  • Compost top-dressing boosts microbiology

Climate Control

  • Steady 70-80°F temperatures
  • 40-60% humidity prevents crisping
  • Draft protection during cold months
  • Air circulation reduces disease risk

To maintain high productivity, prevent blooms by frequent harvesting. Pinch off the tip (just above a leaf node) and repeat this process weekly. This creates a bushier plant, and you have weekly ingredients to cook with. I now have enough basil for several meals each week, while keeping the plants nice and low.

Plan for the seasonal adaptation for year-round success. In summer, use open windows for natural ventilation. In winter, cluster them to increase humidity and use timers to extend the light cycle. At night, I move pots away from the cold glass.

Correctly selecting a container impacts root health. Noting that containers should be 2 inches wider than root balls, and drainage holes are intact. Terra cotta has better air exchange than plastic. I have found that the best places to grow basil are self-watering pots, as these provide consistent moisture levels that improve growth.
