Leptospermum Petersonii (Lemon Scented Tea Tree)

• Native to eastern Australia, this aromatic shrub belongs to the tea tree family and naturally grows in coastal and woodland areas.
• The strongly lemon-scented leaves contain high levels of citronellal oil, traditionally used for its antimicrobial properties.
• Grows as an upright, open shrub reaching 2-4 metres tall with narrow, linear leaves that release fragrance when touched.
• Popular with gardeners for its drought tolerance, attractive flowers, and natural pest-deterrent properties from its aromatic oils.

• Water weekly during establishment, then reduce to monthly deep watering once roots are established, checking soil moisture first.
• Position in full sun locations for optimal growth, though tolerates light afternoon shade in hot climates.
• Plant in well-draining sandy loam or native plant potting mix, avoiding heavy clay soils that retain moisture.
• Apply slow-release native plant fertiliser once in spring, as over-fertilising can reduce oil production and flowering.
• Prune lightly in late winter or after flowering to maintain shape, removing only dead or crossing branches.
• Requires minimal humidity management as it prefers drier conditions typical of Australian native gardens.
• Mulch in summer to conserve moisture and provide winter protection from frost in cooler regions.

• Plant in full sun to partial shade for best growth and oil production. Morning sun with afternoon protection works well in hot inland areas.
• Water deeply but infrequently once established, allowing soil to dry between waterings. Reduce watering significantly in winter months.
• Prefers well-draining sandy or loamy soils with good air circulation. Avoid heavy clay or waterlogged conditions.
• Prune lightly after flowering to maintain shape and encourage bushier growth. Avoid heavy pruning as it may stress the plant.
• Mulch around the base to retain moisture and suppress weeds, keeping mulch away from the trunk.

• Scale insects can attach to stems and leaves, causing yellowing and weakness. Treat with horticultural oil or insecticidal soap applied weekly until cleared.
• Overwatering leads to root rot, particularly in heavy clay soils. Ensure excellent drainage and reduce watering frequency during cooler months.
• Leaf spot fungal diseases may occur in humid conditions with poor air circulation. Improve spacing between plants and avoid overhead watering.
• Psyllids can cause leaf curling and honeydew deposits. Remove affected foliage and apply neem oil spray fortnightly.
