The moon affects where water and energy are located in plants. Our kūpuna knew this and made correlations like the chart below. During those moon phases when there is more water in the roots, it is a good time to plant or harvest certain crops. When there is more water in the trunk/branches, we prune, graft, etc. When more water is located in the leaves, its a good time to harvest fruit, gather medicines (most potent), etc. The below is a helpful guide to show you where the water and energy is in a plant over the course of a month.
