Eucalyptus care guide
Eucalyptus
Also known as: Gum tree, Cider gum, Silver dollar gum, Lemon-scented gum
Pets and children
Considered toxic
The oils in the leaves are reported to be toxic to dogs and cats, causing drooling, vomiting, diarrhea and lethargy; keep it out of reach and consult a veterinarian if any is eaten.
How often to water Eucalyptus
- Spring–Summer (Mar–Sep)
- Every 3 days
- Water thoroughly once the topsoil has dried well, as a guide, and empty the saucer.
- Autumn (Oct–Nov)
- Every 5 days
- Drying slows, so as a guide wait a day or two after the surface dries before watering.
- Winter (Dec–Feb)
- Every 10 days
- Growth slows, so keep it on the dry side and water a few days after the soil dries, as a guide.
Light and placement for Eucalyptus
As a guide, keep it outdoors in full sun with good airflow year-round; it takes summer sun, while indoors it stretches and drops leaves.
Overwintering Eucalyptus
Overwintering guide: −5°C (23°F) or above
Common types such as cider gum and silver dollar gum generally overwinter outdoors in the Kanto area if pots are sheltered from cold wind; tender kinds like lemon-scented gum want a bright spot above 5°C.
Fertilizing and repotting Eucalyptus
Fertilizer
It needs little feeding: as a guide, a small dose of slow-release fertilizer in spring and early autumn, none in midsummer or winter; excess makes soft, floppy growth.
When to repot
Spring–Summer (Mar–Sep), Autumn (Oct–Nov)
Common problems with Eucalyptus
- Overwatering or poorly draining soil causes root rot.
- Once it wilts from drying out completely, it often does not recover after watering.
- Shallow roots and a top-heavy crown let wind blow it over, pot and all.
Tips for growing Eucalyptus
- Stake it, and cut back the tips in spring to keep it low and bushy.
- When repotting, keep the root ball intact and move it to a pot one size larger.
- Cut branches can be hung to dry and enjoyed as dried foliage.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
