How Much Water Do House Plants Need?

For a number of reasons, some plants need more water than others.

More houseplants die because of improper watering than any other problem, according to the University of Missouri Extension. Unfortunately, there is no universal standard for watering houseplants. The amount of water needed to provide a houseplant depends on several factors, including the plant, type of pot and growing medium.

Types

Different types of plants have different water needs, and some plants vary in their preferences depending on their stage in the life cycle. Cacti and succulents like very little water. The Colorado State University Extension recommends providing lots of water to plants producing flowers or buds, plants with large leaves, natives of bogs and marshes, and root-bound plants.

Considerations

The type of pot and planting mixture also affect watering. Clay pots absorb water, so plants growing in these pots need more water. Some soil mixtures also tend to hold water, while others drain quickly.

Expert Insight

Given the many variables that affect the amount of water your houseplant needs, the Texas A&M Extension recommends checking the plant's moisture before watering. Since the roots grow in the bottom two-thirds of the pot, A&M recommends pressing a finger at least that deep. If the soil feels dry, provide water. If the soil feels damp, you're good to go for a while.
