Will the treehouse get higher over time as the tree grows?
No. Trees grow larger by expanding their diameter and growing new branch tips, not by stretching the entire tree. New layers of wood are added during the spring and summer which increase the diameter of trunks and branches. The only part of the tree to get any higher are new shoots, which extend from the ends of branches. Once one season has passed, these shoots will not grow further, but will expand as branches and the trunk do. The following season new shoots will extend from the end of the previous season’s growth. As a tree matures, most species lose their lower branches as they become shaded by the foliage above, leaving a bare trunk. This can give the impression the branches have been lifted higher, when the higher branches are in fact new. As a treehouse is fixed to the heartwood of the tree it will remain at a fixed height from the ground over time.
