Dwarf Cedar of Lebanon problems — and how to fix them
Dwarf Cedar of Lebanon (Cedrus libani 'Nana') is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Cedar aphids (Cinara cedri)
Colonies of large aphids on young shoots produce sticky honeydew and black sooty mould; remove by hand or with a jet of water in early infestations, or use an insecticidal soap spray.
Honey fungus (Armillaria)
Can be susceptible on sites with a history of the disease; affected plants show sudden dieback and honey-coloured toadstools at the base in autumn — remove and destroy infected wood and roots.
