Watering regime

⚠ Phyto-watch (1)
Black spot risk — peak window: sustained wet conditions + warm temperatures
→ 1) TONIGHT: bag all spotted leaves + fallen debris (NOT compost — household trash; spores survive 1yr). Thin crowded canes for airflow. 2) NEXT 4h DRY WINDOW: Cu protectant (preferred: Bordo Bulamacı %1 from agricultural store; stopgap: Yapraq-Cu 4 mL/L + Base 2 + Alga 2, pH 6.0-6.3, NO Bacto in tank). 3) +5 days: Bacto-Line 1.5 mL/L solo foliar (microbiome restore + biological antagonist). 4) Repeat Cu cycle every 7-10d while wet conditions persist.
