Sulphur Sawara Cypress problems — and how to fix them
Sulphur Sawara Cypress (Chamaecyparis pisifera 'Squarrosa Sulphurea') 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.
Tip browning of juvenile foliage in winter or drought
The persistent juvenile foliage is more susceptible to desiccation than adult scale-type foliage; brown tips in spring often indicate winter wind scorch or summer drought stress. Shelter from cold, drying winds and mulch the root zone to retain moisture.
Phytophthora root rot in heavy soils
Poor drainage leads to Phytophthora infection, causing foliage to yellow from the base upwards and the bark at the root collar to turn reddish-brown. Site in well-drained positions and never allow water to pool around the stem.
