Step 3

Mist foliage lightly in early morning or evening to cool leaves (avoid midday misting)

Step 4

Remove only completely browned or dead foliage - avoid heavy pruning during stress

Step 5

Apply diluted seaweed extract spray for rapid cell repair support

Step 6

Monitor soil moisture daily and water when top 2 inches are dry

🌿

Organic Treatment

Step 1

Apply 2-3 inch layer of organic mulch (straw, wood chips, shredded leaves) around plant base, keeping slightly away from stem

Step 2

Water deeply during early morning (before 9 AM) or evening (after 6 PM) when evaporation is lowest

Step 3

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
