Cordyline Torbay Dazzler prefers a warm sunny spot in well drained soil although they will take just a little shade. In cold areas Cordylines may need some winter protection, this can be done by carefully wrapping the crown before the worst cold weather arrives (circle the stem close to the base with gloved hands and then gently move them upwards (minding your eyes on the pointy ends!), the foliage will conveniently fold flat to the stem without damage allowing your assistant to tie it loosely. The plant can then easily be wrapped or covered in fleece or similar which should be removed in Spring when the weather improves.) Alternatively if grown in a pot, move it to sheltered area or unheated greenhouse if that’s easier. In warmer and coastal areas it might not be necessary.
Cordylines benefit from a tidy up in spring, trim off any brown tips and the inevitable dead foliage that is produced close to the base as the stem develops.
