Reviving Established Rosemary in Texas: Drainage, Wind, and Watering

Diagnosing Decline

Three-foot rosemary plants dying after a dry, windy spring with irrigation 3x weekly. Likely causes:

• Waterlogging: Soggy roots are fatal; rosemary demands perfect drainage.
• Wind desiccation: Rosemary hates constant wind; causes leaf browning.
• Irregular watering: Both drought and excess cause stress.
• Pruning timing: Wrong season pruning weakens plants.
• Nutrient deficiency: Lack of lime and organic fertilizer.

Rescue Plan

1. Amend soil with sand/gravel for drainage.
2. Install windbreak (burlap, slatted fence).
3. Water deeply once weekly; skip if rain.
4. Apply liquid fish/seaweed every 3 weeks.
5. Prune 1/3 from top down each branch in spring.

Future Plantings

Choose hardy varieties ('Arp', 'Hardy Hill' to -10°F). Plant on east/southeast slopes with gritty, composted soil.
