- Fruit: Woody, warty capsules (gumballs) with 4-5 valves.
Care Guide
Water deeply but infrequently, allowing the soil to dry out completely between waterings.
Apply a balanced, slow-release fertilizer only if the soil is exceptionally poor.. Eucalyptus trees are heavy feeders but usually extract sufficient nutrients from the soil without extra fertilizer.
Coffee Grounds Compost：Mix used coffee grounds into the topsoil around the drip line to provide a gentle nitrogen boost and maintain slight soil acidity. Avoid thick layers to prevent mold.- Prune young trees to establish a strong central leader and remove co-dominant stems;
- Remove dead, damaged, or crossing branches in late winter before spring growth begins;
- Can be coppiced (cut back to the base) to control size and encourage attractive juvenile foliage.
Toxicity

Pets: Toxic to cats per ASPCA. Essential oils can cause salivation, vomiting, diarrhea, depression, and weakness.
Humans: Leaves are generally safe to handle, but ingestion of concentrated eucalyptus oil can cause gastrointestinal upset and mild toxicity.
Garden Uses & Culture
Culture: Widely planted in California and Southern Europe during the 19th century for timber and to drain swamps, it has become an iconic, albeit sometimes controversial, part of the Western landscape.
Usage: Timber, pulpwood, windbreaks, and extraction of eucalyptus oil for medicinal and cleaning products.
