- 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. Most varieties cannot survive when temperatures drop 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 necessary, but if you must reduce or balance the branches out, act in spring or end of summer. 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 trees have many dormant buds under their bark. These sprout into epicormic shoots – simple branches, actually – whenever the canopy is pruned or damaged. This is how Eucalyptus survives and bounces back after burning in forest fires!
One way of not having side shoots is to plant shrubbery around to reduce light falling on the trunk.
Eucalyptus offshoots and offsides
Eucalyptus is very vigorous. Whenever growing conditions are optimal, it will send shoots up from its roots. 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 a given stump is too large, you might have to dig it out entirely. After that, chop off the root leading to the mother tree.
If digging roots out, once you’ve cut the root coming from the mother tree, let the wound “cure”. This means to let it 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. As a consequence, go around the garden with pruning shears every once and a while as 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 E. gunnii, E. niphophilia or E. globulus.
Eucalyptus is a tree that now grows in many regions of the planet. Many countries in Europe, Latin America, Africa, Madagascar or the Middle East make use of it in gardens and parks.
It bears beautiful leaves that are easy to recognize thanks to their silvery shimmering in the light. Seeing that, the eye is drawn to the trunk, which peels in colorful layers that meld silver, brown and green.
Blooming is only possible in warm climates for this tree native to Australia and Tasmania.
In those countries, the blooming provides excellent nectar for honey.
Dots on each leaf are actually oil glands. These are great for eucalyptus essential oil.
Eucalyptus flavor even appears in mint-flavored chewing gum and in cough drops!
