plantation, planting
栽 centers on putting plants into the ground to grow: planting and the resulting plantation. The idea is deliberate cultivation rather than wild growth.
栽 combines 木 (tree/plant) with a phonetic component that also appears in 裁 and 載. The phonetic likely contributed the sound サイ and the overall structure suggests planting or setting plants into the ground.
The top-left part looks like a tool (戈) digging into the earth (土), and the lower part is a tree (木). Picture a gardener using a tool to plant a tree in the soil.
For サイ, imagine planting a sighing tree: sigh -> サイ, and each sigh helps the tree settle into the plantation.
