How to grow or train it to get the best out of it
A highly fragrant Eucalyptus that unusually grows in part shade as well as full sun. It quickly grows to 5m, with striking heart-shaped juvenile leaves.
Fabulous Specimen Tree for the wider landscape, arboretum collection or avenue planting and for the smaller, medium and larger garden
Commercially: a good choice for open public spaces, parks, business parks, university campus
Growing a full-sized standard: planting the tree and running away is an option, but it won’t necessarily give you the best results.
We suggest you maintain a leading shoot and tip prune the lateral shoots to encourage bushiness. Keep all the sides shoots as they are building up the strength of the main trunk.
- To grow a large specimen, leave the tree to grow up naturally thereafter.
- For a small tree, tip prune the leader when it reaches 1.2m, thereafter let the head develop. Then prune the tree every March 18th and end of May to keep your tree small and bushy.

Growing shrub-on-a-stick clipped standard: this is an opportunity to grow a Eucalyptus in a confined space like a courtyard and also control its overall size. You can produce a small tree on a trunk with a height of anywhere between 2.4m (8ft) and 4m (12ft). Prune back growth every March 18th or thereabouts and tip prune the annual growth back by up to 90% at the end of May. Light tip pruning can be done again during July, but no later. Don’t prune from August through to February.
Growing a multi-stemmed bush or tree. Eucalyptus camphora subsp. camphora responds well to coppicing, once it has attained a trunk of some 125 mm in diameter and readily produces a multi-stemmed specimen
Q: Why would you want to do this?
A: to create:
- a tree with more body or ‘mass’ of branches and foliage for screening purposes. Once grown back up to its full potential, it will now have several main trunks
- an attractive multi-stemmed architectural tree, especially if it has exceptional bark
- to control height, whereby your Euc can be usefully maintained anywhere between 2.4m (8ft) and 7m (20ft), but genetically it will want to grow taller if ignored.
- The practice of coppicing every few years is a great way to control overall size, especially if space is restricted. Regular coppicing also keeps the root-system smaller.
REMEMBER: No grass, no weeds and a thick boring bark chip mulch, to a depth of 150 mm (6 inches) are essential to assist with good establishment. Our research trials have demonstrated that grass around the trunk of Eucalyptus prevent the trees from quickly establishing and can completely stop them from growing.
Pot Culture outdoors: E. camphora subsp. camphora can be successfully grown as a multi-stemmed shrub in a container provided you are prepared to pot on at the recommended intervals and to supply it with sufficient water and food during the growing season.
Always keep pot-grown Eucalyptus in the air-pot container system for healthy and happy trees.😊 They do not thrive in smooth-walled containers ☹

Hedge-Screens: E. camphora subsp. camphora is not on our selected species list for hedge-screens and windbreaks, but they can be grown effectively in a line on farm land as a windbreak and you could grow a row of them as multi-stemmed trees to provide screening.
Floral Art: E. camphora subsp. camphora produces excellent cut foliage for Flower Farmers and floral art. A good choice for clay soils and wet ground. Foliage fragrance is an added bonus of this species.
Firewood Production: E. camphora subsp. camphora is not on our selected species list for Biomass or Firewood. The wood will burn well, but it is not listed for high economic value crop production.

Rural/Agricultural:
- Good shade tree for livestock to stand under. Eucalyptus provide a cool environment for horses, cattle, llamas, sheep to shelter from the sun on hot days, as the mass evaporation of water through the leaves creates a cool shady canopy beneath. Good choice for silvopasture.
- Green foliaged species, which looks for comfortable and not ‘foreign’ in a rural setting – reminiscent of Willow Trees
Ecology:
- E. camphora subsp. camphora produces useful flowers providing foraging for honey-bees and other pollinating insects
- Habitat creation and Game Cover: this species lends itself to providing good trouble-free habitat creation for wildlife and game cover, when planted in groups. Birds enjoy roosting in Eucalyptus trees and Pheasants like rootling around underneath them.
- Chickens: The shredded foliage of camphora subsp. camphora is excellent at keeping Chicken nest boxes and hen houses free of red mites, which detest the presence of Eucalyptol. I used to line our Chicken boxes with shredded leaves, strew the floor and pile up the spindly branches for the chickens to make nests. It was all great till the foxes moved into the next field L
Environmental:
- Growing on the Coast camphora subsp. camphora grows successfully in sight of the sea in Cornwall
To make this work, we recommend that:
- you plant a smaller specimen (5 litre, around 1m-1.2m tall). Call us at the nursery on 07307 413 052 if none of this size are showing for sale – we may have some stock growing on that will be suitable.
- encourage fast establishment in a deeply prepared planting pit (follow our planting advice), to encourage deep rooting to grow an upright, stable tree.
- Staking will be required.
- Newly planted trees will very likely require a wind break shelter for their first winter in the ground with you.
- Zero grass or weeds during the period of establishment is non-negotiable!
- Drying up wet soils E. camphora subsp. camphora is excellent as a Swamp Gum and very at home in moist soils, such as a draining clay, draining peaty/loamy soils and draining sandy loams. It must be remembered that Eucalyptus are not aquatic like a Mangrove, but several species tolerate flooding for up to 6 months of the year in their native lands. This is a great species to help you regain the use of intermittently boggy ground.
- Dry up wet ground that intermittently floods, gain remedial treatment for winter boggy ground or which suffers from outflow from a Septic tank system or unwanted intermittent seasonal ‘ponding’.
- If you have un-usable winter-wet land, planting a group of swamp gums will help towards draining an area of ground. The timber could possibly be harvested to yield a crop of firewood logs too, if coppiced every 6-8 years.
- Please note: Timber harvested from areas suspected to be contaminated with sewage should never be burned, but could be used in rustic garden construction, bug hotel, bean poles, edging pathways & borders etc.
- Sustainable Drainage Systems aka SUDS Needs trialling, but planted singly or in groups, camphora subsp. camphora will most likely draw on drain water percolating into swales or similar. Coppice or pollard every few years if you need to control the overall height of the trees. Eucalyptus draw on ground water for twelve months of the year, unlike willows, which lie dormant for 5 months through the winter.
- Eucalypts grown on continually wet ground The overall height of Eucalypts, grown on continually wet soils in inhabited areas, needs to be considered (as with any tree species of great height), especially in areas subject to strong gales.
- Selecting your tree with a radial root-system is vital and therefore only use Air-Pot grown or air-root-pruned stock.
Eucalypts grown in smooth-walled pots are a ticking-timebomb liability and we can speak from personal experience. Encouraging deep rooting by following our planting recommendations is essential. In addition, it may be prudent to consider pollarding or coppicing after 8 years of growth, to control the height below 10m, to mitigate the risk of the trees being forced over in high winds. Once coppiced/pollarded, it is recommended to maintain overall height at 10m or less thereafter. This practice usually only needs carrying out once every 8 years or so.
- Tolerant of cold and exposed growing environments inland E. camphora subsp. camphora will grow in open fields and pasture, once established.
We recommend
- you plant a smaller specimen (less than 1.8m tall in a 3 or 5 litre air-pot)
- encourage fast establishment in a deeply prepared planting pit (follow our planting advice), to encourage deep rooting to grow an upright, stable tree
- Staking will be required
- In exposed locations, newly planted trees will very likely require a wind break shelter made from horticultural fleece or sail cloth, for their first winter in the ground with you; this very much depends on the level of exposure
- Zero grass or weeds during the period of establishment is non-negotiable!
