About this plant
This form is suited to mild sites only. Eucalyptus have different juvenile and adult foliage, and in the juvenile form the leaves are particularly striking. The young leaves are tapering and coloured blue on their upper surface and white beneath. They are also, at this stage, perfoliate (the paired leaves are joined around the plants stem. Adult leaves are long and lance-shaped and are carried on slender stalks that are attached to the branches. The leaves are coloured blue-green, and reach around 20 cm in length. The tree is also noted for its seed capsules which are twice as big as other eucalyptus found in this country. The capsule is black but with a blue-white bloom. The flowers are white and held in noticeable clusters. This tree is very fast growing and can attain 2 metres in its first season of growth. It is often resown annually from (purchased) seed so the leaves can be harvested. It yields eucalyptus oil which is primarily extracted from this species.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Spring - early · Planting
Prune annually or for reducing size
The plant can either be generally pruned by removing dead or damaged growth and misplaced or crossing branches. When it becomes too large, or if a smaller plant is required, take the plant back to about 3 buds from its base.
Planting & general
Outdoors
Water with rain water
This plant needs rain water or soft water (the minerals in alkaline or "hard" water are harmful). This is especially important for plants in pots.
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Planting
Protect & support young trees
Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
Compost · Planting
Ericaceous compost
This plant requires acidic (ericaceous) soil. Where the soil is not acidic, or when planting in pots, use an ericaceous compost.
