I bought a 16'' wide plastic pot with a built-in saucer. The saucer is removable. On the inside of the pot, there are 4 holes where the saucer connects with the pot and 4 other tiny holes that appear to be drainage holes. How should I prepare this pot for proper drainage for a tropical fruit tree?
My first concern is the proper size of drainage holes - the 4 tiny ones seem like they can clog up easily. How much should I widen each hole?
My second concern is that the drainage holes are currently not at the lowest point of the pot. The center of the pot is the lowest point, but it sits directly on the saucer, so drilling a hole there would not help. My limited understanding of physics is that water will try to flow to the lowest point of any container, so holes that are slightly elevated don't help.
