How to grow Eucalyptus
Whats common across all Eucalyptus varieties in our catalog — drawn from the care records of the 20 most-grown of them.
The Eucalyptus year
- PruneFebruary and March100% of varieties
Perform formative pruning on young trees in late winter to establish a strong central leader.
- Check for PestsJune–August85% of varieties
Monitor foliage for sawfly larvae and beetle damage during the warmer summer months.
- PlantMarch, April, September and October55% of varieties
Plant out young tube stock during autumn to allow root establishment before summer heat.
- FertilizeMarch and April55% of varieties
Apply a slow-release, low-phosphorus native fertiliser sparingly in early spring.
- MulchOctober and November40% of varieties
Apply deep mulch layer to insulate roots, especially for young trees
- PropagateMarch and April35% of varieties
Sow seeds in spring when temperatures begin to rise to ensure rapid germination.
Do
- Water deeply during dry periods 🌱
- Ensure the soil drains rapidly and completely after rainfall.
- Mulch to conserve moisture
- Plant in a position that receives full sun to maintain a healthy, open canopy.
- Ensure the soil drains freely, especially on sloped sites, to prevent root decline.
Avoid
- Do not plant in poorly drained, waterlogged depressions where the tree will rapidly decline.
- Do not apply high-phosphorus fertilisers, as standard low-phosphorus native formulations are safer.
- Do not plant close to houses or structures due to the risk of sudden limb drop and heavy fuel loads.
- Do not plant in humid coastal zones or heavy, waterlogged soils where fungal pathogens thrive.
What goes wrong with Eucalyptus
| Problem | What you'll see | What to do |
|---|---|---|
| Borers | Tunnels in trunks or branches accompanied by gum exudation and sawdust-like frass. | Maintain tree vigour through proper site selection and watering, and prune out heavily infested branches. |
| Aphids | Sticky residue on leaves, distorted growth | Spray with insecticidal soap or neem oil |
| Psyllid | Yellowing leaves and sticky residue | Use insecticidal soap or neem oil |
| Possums and Cockatoos | Chewed bark, broken branchlets, and stripped foliage on young branches. | Install physical tree guards around the trunk of young specimens to prevent climbing. |
| Myrtle rust | Bright yellow-orange pustules appearing on young leaves, stems, and flower buds. | Remove heavily infected tissue, apply registered fungicides if the infection is severe, and maintain good air circulation. |
| Phytophthora dieback | Sudden wilting, collar rot, and rapid decline caused by soil-borne pathogens in wet soils. | Improve soil drainage, avoid over-watering, and apply phosphite treatments where appropriate. |
| Root rot | Wilting and blackened roots | Improve drainage and reduce watering |
Making more Eucalyptus
Seed
- Collect mature woody seed capsules and place them in a paper bag in a warm location until they open and release the fine seed.
- Sow the seed thinly onto the surface of a moist, well-drained seed-raising mix.
- Cover lightly with a thin layer of fine grit or vermiculite and keep moist but not waterlogged in a warm, bright position.
- Prick out seedlings into individual forestry tubes once they develop their first set of true leaves.
Cuttings
- Take semi-hardwood cuttings in late summer.
- Dip in rooting hormone and plant in moist soil.
- Keep humid for 6 weeks until roots develop.
