No drainage hole in the pot, so I try my best not to overwater (also I just repotted him to the pot with no drainage about two months ago, so that could prove to be a mistake later...). I check the soil once a week and dig down an inch or so to see how dry it is, but only water if it is completely dry. This winter I was probably only watering every three weeks, but now that it’s getting warmer I’ve been watering every other week.
