How to Plant Eucalyptus
When to Plant
Plant eucalyptus in spring after the last frost. To find out when that is in your area, use the USDA Plant Hardiness Zone Map.
Where to Plant
Eucalyptus trees need full sun. Choose a spot that gets at least 6 hours of direct sunlight daily.
Soil
These trees prefer well-draining soil. They can tolerate poor soil but do best in slightly acidic conditions. Learn more about soil types from the University of Illinois Extension.
Planting Steps
- Dig a hole twice the size of the root ball
- Place the tree in the hole at the same depth it was in its container
- Fill with soil and water thoroughly
Caring for Your Eucalyptus
Water
Water young eucalyptus trees regularly for the first year. Once established, they’re drought-tolerant.
Fertilizer
Feed your eucalyptus with a balanced, slow-release fertilizer in spring. The Clemson Cooperative Extension offers advice on fertilizing trees.
Pruning
Prune eucalyptus in late winter or early spring to maintain shape and size.
Winter Care
In colder regions, eucalyptus may need protection in winter. Consider wrapping the trunk or planting in a sheltered location.
Common Problems and Solutions
- Leaf Spot: This fungal disease can cause spots on leaves. The University of California Integrated Pest Management Program provides information on managing leaf spot diseases.
- Root Rot: This occurs in poorly-draining soils. Ensure good drainage and avoid overwatering.
- Frost Damage: In colder areas, frost can damage eucalyptus. The Oregon State University Extension Service offers tips on dealing with frost-damaged plants.
Different Types of Eucalyptus
- Silver Dollar Gum (Eucalyptus cinerea): Known for its round, silvery leaves
- Rainbow Eucalyptus (Eucalyptus deglupta): Famous for its colorful bark
- Lemon-Scented Gum (Corymbia citriodora): Has a strong citrusy aroma
