Does eucalyptus wood expand significantly when wet in outdoor tree boxes?
Eucalyptus wood is a popular choice for outdoor applications, including tree boxes, due to its natural durability and resistance to pests. However, a common concern is whether it expands significantly when exposed to moisture.
Like most woods, eucalyptus does absorb water and can expand when wet, but its dense grain structure minimizes excessive swelling. Properly treated and sealed eucalyptus wood performs well in outdoor settings, resisting warping and shrinking better than many softer woods.
For tree boxes, ensuring adequate drainage and using a water-resistant finish can further reduce expansion risks. While no wood is entirely immune to moisture effects, eucalyptus remains a reliable option for outdoor use with minimal expansion concerns.
