Ah, the Eucalyptus Gunnii, a fascinating and versatile tree that can add a
touch of the Australian outback to any garden landscape. Also known as the
Cider Gum, this tree is prized for its aromatic leaves, attractive bark, and
unique appearance. If you're thinking about growing one of these beauties in
your garden, you're in for a treat! Let me guide you through the process.
Getting to Know Eucalyptus Gunnii
Before diving into the growing process, let's get acquainted
with our star plant. Eucalyptus Gunnii is a species of evergreen tree native to
Tasmania and southeastern Australia. It belongs to the Myrtaceae family and is
renowned for its striking silver-blue foliage and tall, upright growth habit.
In its natural habitat, it can reach impressive heights of up to 40 meters
(about 130 feet), but fear not, it can be pruned to maintain a more manageable
size in your garden.
Planting Location
Choosing the right spot is crucial for the success of your
Eucalyptus Gunnii. These trees thrive in full sun and well-drained soil. They
can tolerate various soil types, including clay and sandy soils, but they
prefer a slightly acidic to neutral pH. Ensure the planting area has good air
circulation to prevent fungal diseases and avoid planting in low-lying areas
prone to frost pockets.
Planting Time
The best time to plant Eucalyptus Gunnii is in spring or
early summer, once the risk of frost has passed. This gives the tree plenty of
time to establish its root system before the colder months set in. If you're in
a warmer climate, planting can also be done in early autumn.
Planting Process
- Prepare
the Soil: Dig a hole slightly wider and deeper than the root ball of
your Eucalyptus Gunnii. Break up any clumps of soil and amend with organic
matter if needed.
- Planting:
Gently remove the tree from its container and loosen the roots if they're
tightly bound. Place the tree in the center of the hole, ensuring it's at
the same level as it was in the container.
- Backfilling:
Fill in the hole with soil, firming it gently around the roots to remove
any air pockets. Water thoroughly to settle the soil.
- Mulching:
Apply a layer of organic mulch around the base of the tree to conserve
moisture and suppress weeds. Keep the mulch a few inches away from the
trunk to prevent rotting.
Care and Maintenance
Once your Eucalyptus Gunnii is in the ground, here are some
tips to keep it thriving:
- Watering:
Established trees are drought-tolerant, but young trees need regular
watering, especially during dry spells. Water deeply and infrequently to
encourage deep root growth.
- Pruning:
Eucalyptus Gunnii responds well to pruning and can be shaped to your
desired form. Prune in late winter or early spring to remove any dead or
damaged branches and to promote bushier growth.
- Fertilizing:
Eucalyptus trees are light feeders, so only minimal fertilization is
required. Apply a balanced fertilizer in spring if necessary, but avoid
over-fertilizing, as this can lead to rapid, weak growth.
- Protection:
In colder climates, young Eucalyptus Gunnii trees may need protection from
frost during their first few winters. Wrap the trunk with burlap or use
tree guards to prevent damage.
Conclusion
Growing Eucalyptus Gunnii in your garden can bring a touch
of exotic beauty and fragrance to your outdoor space. With the right care and
attention, this remarkable tree will thrive and become a stunning focal point
in your landscape. So why not give it a try and embark on a botanical adventure
with Eucalyptus Gunnii? Happy gardening!

1. How quickly does Eucalyptus Gunnii grow?
Eucalyptus Gunnii is known for its rapid growth rate,
especially in its early years. Under optimal conditions, it can grow up to 1-2
meters (3-6 feet) per year.
2. How do you shape Eucalyptus Gunnii?
To shape your Eucalyptus Gunnii, prune it in late winter or
early spring. Remove any dead or damaged branches, and selectively prune to
encourage bushier growth and maintain the desired shape.
3. How do you grow Eucalyptus in Canada?
Eucalyptus can be grown in Canada, particularly in regions
with mild winters. Choose a sheltered, sunny spot with well-drained soil.
Consider planting it in a large container that can be moved indoors during
colder months or providing protection from frost with burlap or tree guards.
4. How much space does a Eucalyptus tree need?
Eucalyptus trees can grow to substantial heights, so they
need plenty of space to spread out. Plant them at least 6-10 meters (20-30
feet) apart to allow for their mature size.
5. Where is the best place to plant Eucalyptus?
Plant Eucalyptus in a sunny location with well-drained soil.
Avoid planting in low-lying areas prone to frost pockets, and ensure good air
circulation around the tree to prevent fungal diseases.
6. Can I cut the top off my Eucalyptus tree?
Yes, you can cut the top off your Eucalyptus tree to control
its height or shape. However, it's best to do this during the tree's dormant
period in late winter or early spring to minimize stress.
7. Can Eucalyptus survive winter?
Some Eucalyptus species, including Eucalyptus Gunnii, can
survive winter in milder climates with proper protection. In colder regions,
they may need to be overwintered indoors or provided with frost protection.
8. Does Eucalyptus need to be staked?
Young Eucalyptus trees may benefit from staking to provide
support until they establish a strong root system. Use soft ties to attach the
tree to the stake, and check regularly to ensure the ties are not constricting
growth.
9. Why doesn't my Eucalyptus plant smell?
Not all Eucalyptus species have strongly scented leaves. The
aroma of Eucalyptus leaves is more pronounced in some varieties, such as
Eucalyptus Globulus, while others may have a milder scent or none at all.
10. Where is the best place to plant Eucalyptus Gunnii?
Eucalyptus Gunnii thrives in full sun and well-drained soil.
Choose a sheltered location with good air circulation to prevent fungal
diseases. In cooler climates, consider planting it against a south-facing wall
for added warmth.
11. What is the maximum height of Eucalyptus Gunnii?
Eucalyptus Gunnii can reach heights of up to 25 meters
(about 80 feet) in its native habitat. However, in cultivation, it can be
pruned to maintain a more manageable size, typically around 8-15 meters (26-49
feet).
12. How do you keep Eucalyptus bushy?
To keep Eucalyptus bushy, prune it regularly, especially in
its early years. Remove any leggy growth and selectively prune to encourage
branching. Avoid heavy pruning, as this can stimulate vigorous but weak growth.
13. Is Eucalyptus Gunnii hardy?
Eucalyptus Gunnii is considered moderately hardy and can
tolerate temperatures down to -10°C (14°F) once established. However, young
trees may need protection from frost during their first few winters.
14. How do you overwinter Eucalyptus?
In colder climates, overwinter Eucalyptus by either bringing
potted plants indoors or providing protection from frost with burlap, mulch, or
tree guards. Water sparingly during winter dormancy to prevent root rot.
15. Why is my Eucalyptus Gunnii dying?
Several factors could contribute to the decline of a
Eucalyptus Gunnii, including overwatering, poor drainage, frost damage, pests,
or diseases. Assess the plant's growing conditions and address any issues
promptly to improve its health.
