Yes, these guidelines are suitable for installing kitchen plant shelves for window sills. However, you should take into account the following tips:
Consider the plants' light requirements before choosing a window for shelving. South-facing windows provide the most sunlight while north-facing windows receive the least.
When buying the shelf, opt for an easy-to-clean material that withstands moisture, such as PVC, composite, or treated wood. You may also want to use slatted or grated shelves for better air circulation and drainage.
When planning the window shelf layout, consider plants' heights and growth habits. Additionally, make sure the shelves are deep enough to fit the plant pots and saucers.
