Troubleshooting
Bloomsdale Spinach problems — and how to fix them
Bloomsdale Spinach (Spinacia oleracea 'Bloomsdale') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Bolting
Long days (14+ hours) and temperatures above 24°C (75°F) trigger premature flowering and bitter leaves. Bloomsdale's superior bolt resistance buys extra time, but spring sowing should target harvest before midsummer.
Downy mildew
Yellow patches on leaf surfaces with grey mould beneath, most severe in cool, wet conditions. Bloomsdale has some tolerance; maximise airflow and avoid overhead irrigation. Remove affected leaves immediately.
Leaf miner
White, winding tunnels on leaves caused by Pegomya hyoscyami fly larvae. Cover with fine insect mesh from sowing. Remove and destroy affected leaves; do not compost them.
