About European Cypress (Goldcrest Lemon Cypress)

Cupressus macrocarpa 'Goldcrest' · also called lemon cypress, Goldcrest cypress · houseplant

Lemon cypress (Cupressus macrocarpa 'Goldcrest') is a lemon-scented golden conifer often sold as a small indoor or patio "Christmas tree." It is not listed on the ASPCA toxic or non-toxic plant database, and pet-toxicity reports conflict, so treat it as potentially mildly irritating and verify with your vet before trusting any pet-safe claim.

Growth habit: Columnar, upright evergreen conifer with dense, feathery ascending sprays of bright golden-yellow, lemon-scented foliage that holds its colour into winter. Naturally grows as a narrow cone or pillar; the dwarf 'Goldcrest'/'Wilma' forms favoured as houseplants stay slow and compact in a pot.

What fertiliser european cypress (goldcrest lemon cypress) actually wants — and why

European Cypress (Goldcrest Lemon Cypress) is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.

A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry.
