Lemon myrtle is a beautiful aesthetic addition to any garden and we have stock at the nursery now.
Lemon Myrtle (Backhousia citriodora) is an absolute delight for any garden. It’s a small growing native tree with leaves that release a strong lemon scent when crushed or after rain. In spring new growth is tinged red and in summer you’ll get abundant clusters of creamy white flowers which are loved by butterflies. Lemon myrtle is quite versatile and can be used as a screen, hedge or feature tree and is suitable for most gardens and courtyards.
How To Grow Lemon Myrtle
Originally a rainforest tree, lemon myrtles prefer good soil and warm conditions. In milder areas they can handle full sun positions but in hot dry climates plant in dappled shade. Protect young trees from frost but older tress are more tolerant.
Enrich the soil before planting with plenty of organic compost and manure to encourage better growth. Apply a gypsum product if the soil is heavy clay as this will help to break it up and improve drainage. Once planted water in with a high quality seaweed or liquid fish fertiliser and then mulch around the base. If you are short on space you can grow a lemon myrtle in a large pot but make sure you keep it moist during hot, dry weather.
Climate will affect the height of the tree but on average expect about 4m by 2m wide; taller in warm areas and less in colder areas. Height and shape can easily be maintained by pruning if required.
Fertilising Lemon Myrtle
When trees are young and establishing apply a mixture of seaweed (every 2-3 weeks) and a slow release fertiliser quarterly to maximise growth. If growing in pots then keep this treatment up as well (and you can increase fertilising frequency to monthly). For established trees in the ground a layer of compost or manure every spring and autumn is usually enough to keep them happy. Don’t forget to top up the mulch as well.
Pruning Lemon Myrtle
If using lemon myrtle as a screen or hedge then regular light pruning will be required to encourage dense growth. If growing as a feature tree then choose a specimen that has a single trunk and as the plant grows remove lower branches to create a “tree” shape.
