Add compost, worm castings, and biochar to soil to improve water retention and heat resilience

Step 4

Install shade cloth (30-50% density) or move container plants to shadier location

Step 5

Trim only severely scorched leaves and dead flowers to redirect energy toward healthy recovery

Step 6

Apply liquid seaweed extract or fish hydrolysate to support cell repair and hormone balance
