Troubleshooting
Good King Henry problems — and how to fix them
Good King Henry (Blitum bonus-henricus) 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.
Slow to establish
Seed germinates erratically and plants are weak in year one; do not crop heavily until the second season. Be patient and let the crown build strength first.
Bolting and bitter leaves
Hot, dry conditions push plants to flower and toughen the leaves. Keep soil moist, harvest young, and remove flower spikes to prolong leaf production.
Downy mildew and leaf spot
As a goosefoot relative it is prone to mildew and fungal spotting in damp, crowded sites. Space plants, improve airflow, and remove affected foliage.
Oxalic acid build-up
Mature raw leaves are high in oxalates and best cooked. Harvest young leaves and cook them, and eat in moderation rather than as a staple.
