Growing notes
- Sage tolerates drought and poor fertility — over-watering and rich soil are common failure modes.
- Good air circulation is critical to prevent foliar disease; don't crowd it.
- Prune lightly each spring to keep the plant from getting leggy and woody.
- Replace plants every 3-5 years as crowns decline.
- In humid climates, increase the pumice/sand share another 5-10% for extra drainage.
