Move your tulsi plant indoors to protect it from frost.
Ensure the plant receives at least 4-6 hours of sunlight daily.
Water sparingly to avoid root rot in the cold, damp season.
Add organic mulch to retain warmth and moisture around the roots.
Use a cloth or plastic sheet to shield the plant from freezing.
Reduce fertilizer use as tulsi growth slows during winters.
Prune unhealthy leaves to encourage healthier growth and vitality.
