What is the best time to water house plants, during daytime or during nighttime?
“There is no magic formula or timetable for watering house plants. Since temperatures, light and humidity tend to change, it is not practical to water house plants on a set schedule. The best way to tell if a plant needs water is to feel the soil and see how dry it is. When the top inch of soil is dry, it is time to water. Top watering and bottom watering are both acceptable methods. With bottom watering, salts may accumulate in the soil and need to be flushed out from the top periodically. When watering from the top, apply water until it comes out the drainage hole. Let the plant sit in the water in the saucer about 15 minutes, then drain off the excess water. When watering from the top, be sure to apply the water evenly to the soil surface. If all the water is applied in one spot, a “pipeline” might develop and water will flow through without wetting the soil.” (source http://web.ext
