English Walnut 'Franquette' problems — and how to fix them
English Walnut 'Franquette' (Juglans regia 'Franquette') 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.
Late, light cropping
As a tip-bearing cultivar 'Franquette' often yields less than lateral-bearers like 'Chandler' and may take longer to come into bearing. Patience and good pollination help.
Spring frost despite late leafing
Its very late budbreak greatly reduces frost loss, but severe late frosts can still damage emerging shoots. Avoid deep frost pockets.
Walnut blight in wet springs
Though more blight-resistant than many cultivars, it is not immune; prune for airflow and use approved copper sprays where blight pressure is high.
Codling moth and walnut husk fly
These pests bore into and stain nuts. Trap, time controls, and clear fallen infested nuts to reduce carry-over.
