Lemon eucalyptus
Corymbia citriodora
A fast-shooting, lemon-scented eucalypt that races for height and dappled shade while yielding aromatic oil. Frost-shy when young and its oily litter can crowd out neighbours.
Lemon eucalyptus in a syntropic line
Lemon eucalyptus belongs in the Emergent layer as a Secondary biomass species. They frame the line. Rough in-row spacing starts around 1.3 m in a syntropic row. Good line partners include Almond, Apricot. As a Secondary species it carries mid-term yield and structure while climax trees slowly claim the canopy.

How to manage it
Formative prune while young to encourage lower branching and denser leaf biomass; established trees can be pollarded for mulch and oil harvest.
How to propagate
Sow seed on moist sand in spring; germinates readily in warm conditions.

What to watch out for
Oily, citronella-scented foliage is highly flammable and mildly allelopathic to understory plants. Frost-tender for its first few winters and can self-seed into a weed in mild, wet climates.
Frequently asked questions about Lemon eucalyptus
Is lemon eucalyptus frost-hardy?
Yes for winter cold in many climates — generally hardy to around -3°C when dormant, with low frost tolerance in the catalog. Flowering crops can still lose a season to late frost, so site them carefully.
What soil does lemon eucalyptus need?
It does best on sandy, loam ground, at pH about 5.5–7.5.
How much water does lemon eucalyptus need?
Plan for a rainfall floor around 600 mm/year, plus low irrigation once established.
Can lemon eucalyptus handle wet or waterlogged soil?
It has medium waterlogging tolerance — short winter wet is usually fine, standing water is not.
What should I watch out for with lemon eucalyptus?
Oily, citronella-scented foliage is highly flammable and mildly allelopathic to understory plants. Frost-tender for its first few winters and can self-seed into a weed in mild, wet climates.
