Key takeaways

Avoid pruning in warm, humid weather because of myrtle rust.
Check whether the tree is protected before pruning, especially near the coast.

Best time to prune

Manaaki Whenua advises pruning myrtle-family plants, including pōhutukawa, in late autumn and winter (May to August) or in the drier summer months of January and February. Myrtle rust is less likely to take hold when it's cold, or hot and dry.

Pōhutukawa usually flower in December, so pruning in winter also means you won't cut off the summer flowers.

Why myrtle rust matters

Myrtle rust is a fungal disease that attacks plants in the myrtle family, including pōhutukawa. Pruning triggers new growth, and young leaves and stems are the most vulnerable to infection. Pruning at the right time gives that new growth the best chance.

If you see bright yellow or orange powdery patches on leaves, don't touch the plant. Take clear photos and report them to the MPI Exotic Pest and Disease Hotline on 0800 80 99 66.

How much to take off

Pōhutukawa regrow readily, and Tāne's Tree Trust notes they're suited to having lower branches removed to lift the canopy. That's often the best way to open up a view or let light into the garden without spoiling the tree's shape.

Heavy pruning tends to trigger lots of new shoots along the branches. That means more regrowth to manage, and more young growth exposed to myrtle rust. A careful, lighter prune usually gives a better result.

Check before you prune

No type of tree is automatically protected in Auckland, but many pōhutukawa grow near the coast, where coastal rules can apply. Some are also listed as notable trees. Here's how to check whether a tree is protected.

Big trees

Pōhutukawa can grow to around 20 m with a very wide crown, and their roots can spread well beyond the canopy. For a large tree close to the house or over a cliff, a specialist arborist is often the right call, and I'll tell you if that's the case.

Need a hand?

I can lift and thin pōhutukawa in the right season and take all the branches away. See tree trimming or get a free quote.
