- Position: full sun
- Soil: neutral to slightly acidic soil that doesn't dry out
- Rate of growth: fast-growing
- Flowering period: July to October
- Flower colour: white to cream, but not often seen in Britain
- Other features: usually grown with multiple stems as it seemsto cope with strong winds better
- Hardiness: borderline hardy (may need winter protection)
A magnificent tree with flaking bark in shades of grey, cream, green and brown. It has silvery-blue, rounded young leaves which give way to long, glaucous, sickle-shaped adult foliage. It is probably the most well-known gum in this country as it is often seen in milder garden, where it is completely hardy except in abnormally cold winters.
- Garden care: Requires minimal pruning if grown as a tree, removing any broken, diseased or crossing branches in late autumn or winter. For the best juvenile foliage, prune in early spring cutting back the stems to two or three buds above the base. When planting incorporate lots of well-rotted garden compost in the planting hole and stake firmly.

Q:My colleague has recommend this plant (eucalyptus) for my garden and prune it hard annually to give the pretty immature round leaves. If taking this approach how much space should I allow approximately as I assume it won't reach full height and spread. What would the height and spread likely to be after 1 year?Asked on 4/30/2013 by emi from Northamptonshire
It is hard to be too specific as the growth rate will largely be determined by external factors such as the available water, light and nutrients, but as a rough estimate, I would say you should allow between 1.5 - 2m height and spread in each years growth.Answered on 4/30/2013 by Helen from Crocus

Q:Eucalyptus tree pruning advice
I have a fairly large Eucalyptus tree in my garden which I have previously pruned (severely) in the spring. It now needs to be done again but should I wait until the spring again or could it be done now, I want it to re-shoot like it has done previously. Many thanks MariaAsked on 9/29/2009 by Maria Hunt
A:Hello Maria, These should only be pruned from late winter to spring, just as the new growth is beginning. In colder areas, you should wait until after all the hard frosts have passed. I hope this helps. Helen Plant DoctorAnswered on 9/29/2009 by Crocus Helpdesk
Q:What is wrong with my Eucalyptus?
Hi Please could you help us? The leaves of our Eucalyptus are spotted and pitted with lots of reddish brown "pimples" and they are now starting to fall off in great numbers. Thank you so much for reading this Sincerely PatriciaAsked on 6/19/2009 by Anonymous
A:Hello Patricia, Eucalyptus are prone to oedema, which causes raised, wart-like growths to appear on the leaves. These start out the same colour as the leaves and then gradually turn brown and woody. This is caused by the plant taking up more water than it can lose through its leaves, so keep an eye on the watering to see if it lessens. Alternatively it may simply be the shedding of old foliage, which is quite normal. As evergreen plants put on new growth, they will lose some of their older foliage. I hope this helps.

Q:How big will my Eucalyptus gunnii get?
My neighbour is very concerned about my Eucalyptus gunnii. She is convinced that it will grow 100ft high and invade her drains.Asked on 8/1/2005 by email@example.com
A:Eucalyptus gunnii does have the potential to grow to around 80ft tall, although they can be cut back hard each year to restrict their growth. They will however develop a large root system, which may cause damage to the pipes if there are any in the vicinity.Answered on 8/2/2005 by Crocus
Q:What is wrong with my Eucalyptus?
My newly planted Eucalyptus tree is dying. It is on an east facing side of the garden so gets plenty of sunlight until 2pm. Its leaves are turning brown from the bottom up and the top tender branches are wilting. Is it too little or too much water?Asked on 6/30/2005 by Adele Harrison
A:Eucalyptus are usually pretty resilient, however dry leaves are usually caused by a lack of water. Newly planted trees do need to be kept well watered for their first year or so, as they will still be establishing a good root system.Answered on 7/1/2005 by Crocus
