Sweet Chestnut 'Bouche de Bétizac' problems — and how to fix them
Sweet Chestnut 'Bouche de Bétizac' (Castanea sativa × crenata 'Bouche de Bétizac') 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.
Spring frost on early buds
Its early budbreak makes new growth sensitive to spring frosts, which can damage flowers and reduce that year's crop.
Needs a pollination partner
Largely self-incompatible; plant a second compatible chestnut cultivar nearby for reliable, full nut set.
Chestnut blight variability
Generally resistant to gall wasp and fairly resistant to blight, but blight susceptibility has been reported in some regions, so source clean stock.
Alkaline-soil chlorosis
On chalky or alkaline soils it suffers chlorosis and poor growth; it needs acidic to neutral, well-drained ground.
