Originally a rainforest tree Lemon Myrtle prefers good soil and warm conditions. In milder areas they can handle full sun positions but in hot dry climates plant in dappled shade.
I have had a couple of goes at growing this aromatic leaved tree. The first time was in a sheltered position overlooking Lake Macquarie just north of Sydney Australia. It did very well and was healthy. My second attempt however was plagued with Myrtle Rust. Myrtle rust attacks new growth and young plants seem to be more vulnerable than established trees. It is characterised by small lumpy spots that develop a reddish purple halo and yellow clusters of spores.
It can be treated by removing all infected foliage and spray thoroughly with a fungicide however in my current location I was advised to remove and destroy the tree.
Used fresh, the Lemon Myrtle leaf is a most versatile and refreshing herb. For storage, the leaves are cool dried (to prevent loss of essential oils) and then ground and stored in a cool, dry manner for later use.
