Eucalyptus
Eucalyptus gunnii
Renowned for its distinctive, silvery-blue foliage and invigorating menthol-like fragrance, the Eucalyptus (specifically the Gunnii variety) is a striking addition to any bright indoor space. Originally native to Australia, these fast-growing evergreens feature rounded juvenile leaves that eventually transition into long, lance-shaped adult leaves. While challenging to maintain indoors long-term, their aesthetic appeal and aromatherapy benefits make them a favorite for many plant enthusiasts.

Care Guide
Indoor Care for Eucalyptus
Light Requirements Eucalyptus trees are sun-lovers. They require at least 6 to 8 hours of direct sunlight daily. A south-facing window is ideal. If you notice the stems becoming 'leggy' or the leaves losing their silver color, it likely needs more light.
Watering Routine These plants prefer consistent moisture. Water when the top inch of soil feels dry. Do not allow the root ball to dry out completely, as this can lead to leaf drop and crisping. Ensure your pot has excellent drainage to avoid root rot.
Soil and Repotting Use a well-draining potting mix rich in organic matter. Because they grow so fast, you may need to repot your Eucalyptus every spring. Be careful with the roots, as they are quite sensitive to disturbance.
Pruning To keep your plant at a manageable indoor size and maintain its bushy, rounded juvenile foliage, prune regularly. Pinching off the tips will encourage lateral growth.
Seasonal Considerations In winter, growth will slow down. Reduce watering frequency and stop fertilizing until spring returns. Keep the plant away from cold drafts and heating vents.
