Cedar aphids (Cinara cedri)
Large, grey-brown aphids that congregate on new shoots in spring, excreting honeydew that leads to sooty mould; treat with a strong water jet or an approved insecticidal soap.
Root and collar rot (Phytophthora)
Poorly drained or overwatered soils invite Phytophthora root rot, causing yellowing needles and sudden dieback; improve drainage before planting and never allow water to pool around the stem base.
