timber, trees, wood, establish, set up
樹 centers on woody plants and the act of making something stand firmly: trees, timber, and the idea of establishing or setting up something lasting.
樹 combines 木 (tree) with 尌, which likely contributes the sound and the idea of standing upright. The character originally referred to planting or setting up trees.
A tree 木 stands beside 尌, which looks like a hand 寸 planting a sapling 豆 in the earth 土. Together they show a tree being established.
For ジュ, imagine a jeweler carefully setting up a display of wooden jewelry: jeweler -> ジュ, and the wood comes from trees.
