Water use was not constant during the study; small plants used 1 tablespoon per day, while large plants used slightly less than 2 tablespoons per day. Overall, there was a good correlation between plant growth and the amount of water applied.

How often should you water houseplants? Most houseplants need watered every 1-3 weeks. You should monitor your houseplants and water when they need it, rather than on a schedule. Frequency of watering will depend on the size and type of plant, size and type of pot, temperature, humidity and rate of growth.

Do plants need watering every day?
There is no simple rule of thumb for watering as each plant has different needs – for example, a container plant in hot sunny weather may need watering daily, whereas a mature shrub might only need a drink in extreme drought.
All plants need water to survive, although some get moisture from the air and don’t need direct watering. Even a cactus needs water, but too much can cause it root rot and too little will see it shrivel. In fact, over watering is the most common cause of death in indoor plants.
Make a habit of checking on your houseplants at least once a week to see if they need a drink. The best way to tell if your plants need water is to stick your finger about an inch into the soil mix ($10, Lowe’s), and if it feels dry, break out the watering can.
Light. As with watering, every plant has different light requirements. Many plants prefer direct sunlight, but this may be hard to get inside a house. Placing a plant in a window might offer enough light, but some houseplants will need supplementing from a grow light (see Lighting Indoor Houseplants).
Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation, but don’t worry about leaf scorch. It’s usually best to apply water directly to the soil around plants rather than watering with a sprinkler. Less water is lost to evaporation, especially on hot, sunny days.
