I just had some thoughts about the catch tray underneath your pot. A couple of hours after watering your plant, it would be a good idea to check and see if the tray is still filled with water, or not. If the tray is still filled with water, it would be a good idea to empty it because if it’s filled with water, it’s equivalent to the plant’s roots sitting in water in a pot with no holes in it.
Also, it would be a good idea to put a pad, a placemat, or maybe even a towel underneath the catch tray. If the tray overflows, and there’s nothing beneath it to absorb the water, it’s going to stain your table. I’ve had that happen to a wood table, and also to a table made out of bronze that got so discolored from water stains that it was necessary to refinish the table top. In any case, it’s important to have something underneath the catch tray.
A plant should be put in a pot that is appropriate for its size. A plant in the container that is too small can become root bound meaning that there is no room left in the pot for the roots. On the other hand, if a plant is in a container that is too big, the soil may not hold water for very long, and can become dried out quickly. If when you check the plant, you see there are more roots than soil, that is a good indication that it’s time to repot the plant. You only want to move plants up one pot size at a time to ensure that it is not potted in a container that is too big. If the pot has ever tipped over because the leaves are too heavy, that is a good indication that it’s time to move it to a bigger pot.
Whenever you go out to buy a pot for your plant, always remember to also get a tray, or dish to go underneath it to catch the water that drains out of the holes in the bottom of the pot. You definitely want one of these so that the water does not spill onto the table, or onto the floor. You can buy plastic pans for this purpose, or you can improvise by using something that you can find at home. Once, I used a Frisbee as a catch pan for a pot.
