- Health: benefits of eucalyptus
Eucalyptus is a tree that is best planted in fall or at the beginning of spring.
Its growth is quite fast and it doesn’t require any particular care.
- Choose a rather sunny spot, ideally well protected from strong winds.
- Incorporate planting soil mix into your garden soil when planting.
- Endeavor to water well over the 1st year after planting.
Proper mulch will avoid having weeds proliferate around the trunk and will protect the root system when winters are cold, especially during the first few years.
Pruning and caring for eucalyptus
Eucalyptus care is very easy because it requires practically no attention at all once it has settled in comfortably.
Pretty hardy, eucalyptus has no known common disease. It sometimes is attacked by psyllids.
However, it is at times vulnerable to the cold, and most eucalyptus varieties cannot withstand temperatures below 23°F (-5°C).
- Thick mulch around the tree for the 1st few years should help it cope with winter freezing well.
How to prune a eucalyptus tree
No pruning is required but if you must reduce or balance the branches out, act in spring or end of summer for pruning. Abundant sap makes for quick wound-closing and healing.
- Avoid pruning or wounding your tree in winter or in very moist weather to keep fungus out.
Eucalyptus offshoots and offsides
Eucalyptus is very vigorous and if growing conditions are optimal, it will send shoots up from its roots, much like the strong root stock of certain grafted fruit trees in an orchard. These are called root suckers.
Here is how to deal with eucalyptus root suckers:
- Snip them off as soon as you see them. Mowing the lawn usually does the trick.
- For larger specimens, cut them down with lopers or a saw or machete.
- If the stump is too large, you might have to dig it out entirely, severing the root to the mother tree
If digging roots out, once you’ve cut the root coming from the mother tree, let the wound “cure” or dry in shaded air for a couple hours before filling the hole back in.
There’s no permanent solution to keep the eucalyptus from sending shoots up, so going around the garden with pruning shears every once and a while must become part of your regular garden routine!
All there is to know about eucalyptus
Native to Australia, Eucalyptus is a member of the Myrtaceae family. Although the geographical point of origin is on the other side of the world, Eucalyptus radiata or narrow-leaved peppermint has adapted to many climates in the western hemisphere, together with other eucalyptus species such as Eucalyptus gunnii, Eucalyptus niphophilia or Eucalyptus globulus.
Eucalyptus is a tree that can be found in many regions of the planet, like Europe, Latin America, Africa, Madagascar or the Middle East.
It bears beautiful flowers that are easily recognized thanks to their silvery shimmering in the light. Its trunk peels in colorful layers that meld silver, brown and green.
Blooming is only possible in warmer climates for this tree native to Australia and Tasmania.
In those countries, the blooming provides excellent nectar for honey production.
The leaves are peppered with oil glands, which makes it great for producing eucalyptus essential oil.
Eucalyptus flavor even appears in mint-flavored chewing gum and in cough drops!
