Since I am a vigorous plant I need plenty of water from spring to fall. You should water me every second or third day, but remove surplus water from the tray after about ten minutes. After that the upper layer of soil can dry out slightly before you water me again. In order for me to thrive my roots need lots of drainage. So there should be air between my pot and the flowerpot holder or tray. I do not tolerate being planted directly into a flowerpot holder. In the fall and winter I do not grow as much and do not need to be watered as often.
