Creating Your Indoor Therapeutic Garden: Practical Tips
Optimal location: Choose south or west-facing windows for Mediterranean plants (rosemary, thyme, oregano) and east or north-facing for plants preferring less direct sun (lemon balm, parsley).
The right substrate: Use quality draining potting soil. Add 20% perlite for Mediterranean plants that hate stagnant moisture.
Smart watering: Most failures come from excess water. Always check soil moisture before watering. A finger inserted 1-2 inches effectively tells you what you need to know.
Psychological benefits: Growing these best herbs for mental health offers a daily meditative practice. Observing growth, regular care, and connecting with living things significantly reduces cortisol levels (stress hormone).
