Almond 'All-in-One' problems — and how to fix them
Almond 'All-in-One' (Prunus dulcis 'All-in-One') 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.
Frost-damaged blossom
Almonds bloom in late winter, so late frosts readily kill flowers and abort the crop. Site in a frost-free pocket or against a warm wall, and protect early blooms in cold snaps.
Brown rot (Monilinia)
Blossoms and twigs blight, and developing nuts rot, especially in wet springs. Remove mummified nuts and infected wood and improve air circulation; preventive sprays help in damp climates.
Peach leaf curl / shot hole
Fungal leaf diseases distort and pock the foliage in wet weather. Rake up fallen leaves, prune for airflow, and apply a copper spray at leaf fall and bud swell where pressure is high.
Navel orangeworm and other nut pests
Larvae infest splitting hulls and feed on kernels. Sanitation, removing leftover mummy nuts over winter, and timely harvest are the main controls.
