Don’t touch them – snap them – and upload. Got some clear pictures of the host plant? Even better – these can help our experts confirm the symptoms indicate myrtle rust. The pictures of rohutu and ramarama (bubble leaf) keep coming – testament to the extreme vulnerability of these species to myrtle rust. Keep it up but also – it would be great if people could keep a special look out for pōhutukawa right now. Unfortunately reports are trickling in that even mature trees are now being impacted – especially on the ‘epicormic’ growth (new growth coming from old branches.)

Plants in the Myrtaceae family (myrtles) are at risk from dieback and death from myrtle ...more ↓
