Similarly, you may ask, how long do pohutukawa trees live?
Pohutukawa can live for hundreds of years in their natural coastal environment. While it is common to see 100-year-old trees growing in home gardens, both pohutukawa and northern rata can probably live up to 1000 years.
Simply so, do pohutukawa trees flower every year?
Yes, you will get flowers over months, but you only get a few flowers at any one time and the whole thing about the pohutukawa is that beautiful mass of bloom around Christmas. Ditto the yellow forms of M. excelsa.
Undertake any work when the tree is most dormant – i.e. mid winter. However, reducing the size of a pohutukawa is not easy. If you cut large branches back you will precipitate epicormic growth back along the remaining branch which thickens up the within tree foliage.
