Hello I have a related question. I live on the NSW coast about 100kms north of Sydney and have about 6 miniature pohutukawas (NZ Christmas trees) growing in my garden. They were planted about 5 years ago and are doing very well but steadfastly refuse to flower. They look as though they are going to bud but never quite make it which is very disappointing. Should I be doing something to encourage the flowering process? Thanks in anticipation.
