Chestnuts require full sun; however, Castanea spp. are rated USDA zones 4–8 and are not recommended for NE Florida zone 9b — they require cool winters to break dormancy and produce nuts.
Chestnuts need moderate, well-distributed moisture; they are not suited to NE Florida zone 9b's mild winters and would require zones 4–8 to thrive and produce nuts.
Chestnuts prefer deep, well-drained, acidic soils; both American (C. dentata, zones 4a–8a) and Chinese (C. mollissima, zones 5–8) chestnuts exceed their heat tolerance in zone 9b Florida and are not recommended by UF/IFAS for this region.
