I have found my Peace Lilies need more water than the Spiders they share space with. Both need plenty of water but in different ways. I leave my Peace Lilies dry out and then water them until the water is coming out the bottom of the pot. I will leave them suck up the standing water and then I will ignore them until they are dry again. I have great success with my method.
The girl who helps me uses a water wand and I guess I am old fashion but the want may say it is dry in one spot or even several spots., when in fact the plant is not getting the proper water it should have. It works on the smaller plants but for the big ones I prefer just using my own judgement and keeping a regular watering schedule.
