Reviving Indoor Basil & Rosemary: When to Restart vs. Rescue

Your basil is likely done—woody base, withering new growth, and whitish leaf tips indicate root stress, insufficient light, and/or cold damage. Basil is an annual; it declines after flowering and doesn't recover well indoors.

Rosemary Rescue Plan

Rosemary is perennial but hates indoor winter conditions. To save it:

• Pot up: 10–12" deep container, sterile well-draining mix
• Light: South/east window + 16 hrs fluorescent (cool + warm white tubes, 4–6" above)
• Water: Sparingly—finger test 1" deep. Never cold tap water.
• Air: Oscillating fan on low; avoid heat vents
• Prune: Trim ⅓ of new growth every 3 weeks to prevent woody buildup
• Fertilize: Fish/seaweed every 3 weeks

Fresh Start Strategy

• Basil: Buy new plants when nights stay >60°F. Sow succession crops outdoors.
• Rosemary: Plant hardy varieties ('Arp', 'Hill Hardy') in ground if zone 7+. Otherwise, keep potted and move out after frost.

Indoor herb success requires mimicking outdoor conditions—most homes fall short. Invest in grow lights and airflow for winter growing.
