Indoor Care Tips for Eucalyptus gunnii
- Light: Requires full sun; minimum 6 hours daily near a south-facing window or outdoors in summer
- Watering: Let the top 3–5 cm of soil dry before watering deeply. Avoid soggy soil
- Humidity: Prefers dry air; no misting required
- Temperature: Thrives at 15–30°C. Not frost-hardy in pots — protect below 5°C
- Soil: Well-draining, gritty mix with added perlite or sand
- Repotting: Repot annually or when rootbound; use tall pots with drainage holes
- Fertilizing: Lightly feed in spring and summer with a low-nitrogen liquid fertilizer
- Pruning: Prune in early spring to maintain shape and encourage fresh juvenile growth
- Propagation: Best propagated from seed; cuttings are difficult and slow to root
Common Problems and How to Fix Them
- Leggy Growth: Move to a brighter location and prune for bushier form
- Leaf Drop: May result from root rot or cold stress. Check soil and temperature
- Pale Leaves: Suggests poor nutrition — add a balanced slow-release fertilizer
- Yellowing: Caused by overwatering. Let soil dry thoroughly between waterings
- Pests: Occasionally affected by aphids or scale. Use insecticidal soap or neem oil
Helpful Tips for Long-Term Growth
- Rotate regularly for even growth
- Use a stake if stems lean after pruning
- Harvest young stems for fresh or dried arrangements
