What are the best soil types for eucalyptus outdoor tree boxes?

Eucalyptus trees thrive in well-draining, slightly acidic to neutral soil. For outdoor tree boxes, the best soil types include sandy loam or a mix of potting soil with perlite or coarse sand to ensure proper drainage. Avoid heavy clay soils, as they retain too much moisture and can lead to root rot. Adding organic matter like compost can improve soil fertility and structure. Regularly check soil pH (6.0-7.0) and moisture levels to maintain ideal growing conditions for your eucalyptus tree.
