Almond 'Tuono' problems — and how to fix them
Almond 'Tuono' (Prunus dulcis 'Tuono') 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.
Brown rot and blossom blight
Monilinia infects flowers and fruit in wet springs, browning blossoms and rotting nuts. Fungicide at bloom, good airflow and sanitation of mummified fruit reduce losses.
Spring frost on bloom
Even late-blooming 'Tuono' can lose its crop to a hard frost during flowering. Avoid frost pockets and choose a sheltered, warm site for dependable set.
Peach leaf curl and shothole
As a stone fruit, almond is prone to Taphrina leaf curl and shothole (Wilsonomyces) in damp climates, distorting and perforating leaves. Dormant copper sprays help; dry sites have far less trouble.
Poor fruiting in cool, wet climates
Almonds need hot, dry summers; in cool maritime regions like much of the UK they grow but seldom ripen good crops. Match the cultivar to a warm, sunny microclimate.
