Chinese Hazel problems — and how to fix them
Chinese Hazel (Corylus chinensis) 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.
Limited availability
Rarely offered in the nursery trade and mostly seen in botanic collections, so sourcing plants or seed can be difficult outside specialist suppliers.
Needs space
Its eventual size makes it unsuitable for small gardens; site it where a forest-scale tree can develop fully.
Eastern filbert blight (relatively tolerant)
Asian hazels generally show good resistance to Anisogramma anomala and are used in resistance breeding, but monitor for cankers where the disease is present.
Wildlife competition for nuts
Squirrels and other wildlife readily take the nuts; on a large tree much of the crop is out of easy reach for harvest.
