In the course of general research, I came across someone who said they mulched potted plants (trees specifically) with buckwheat hulls because they are pretty, break down over time, and contribute to good drainage when they get mixed in during regular top-dressing. Also mentioned that they help keep pests at bay and regulate temperature.
Before I follow this example because why wouldn't I with all those benefits... well...
1. Why shouldn't I?
2. Should I wait until they are a certain size?
3. Would this be good for potted herbs, too?
4. Is there another mulch that would be better to use when I plan to keep plants indoors at least part of the time and fertilize regularly, so I'm not SUPER concerned about them adding nutrition, but drainage and temperature are important?
TIA for any advice!
