Additional Strategies for Your Zone

• Start seeds in protected cells (greenhouse, cold frame) then transplant.
• Use raised beds with sandy-loam-compost mix for drainage.
• Select heat-tolerant varieties: basils, holy basil, lemongrass, roselle, Mexican mint marigold (Texas tarragon).
• Mulch heavily (3–4") to buffer soil temperature and moisture swings.
• Drip irrigation with timer prevents over/under watering.
