3. How little is too little?
There is no set rule in watering houseplants. Some cactus can retain water in its stems for up to two years! Other plants need to be kept uniformly damp in the water root zone. Your plant will tell you it’s thirsty by wilting and, if you leave it long enough, by dying. If the soil is wet or soggy, you’re watering too much. If it’s just damp, don’t add water yet. If it’s dry on the surface and for an inch below, it’s time to water. Get to know your plant and use those powers of observation.
