How to Bottom Water Your Plants

Answer: Bottom water your thirsty and moist-soil loving plants by placing the pot in a saucer of water. Leave it for 20 minutes to let the soil absorb the water from the saucer.

What is bottom watering and why is it important?

Plants that are watered from the bottom require a different watering technique than top-watered plants. Watering from the bottom is also known as "sub-irrigation" and it works by keeping the soil at a constant dampness level below the surface of the soil, instead of allowing it to dry out completely between waterings.

Bottom watering is ideal for houseplants that like consistently moist or wet soil. Plants like Begonias, Calatheas and Peperomias like moist soil at all times. On the contrary, plants that love drier soils like succulents, string of pearls and cacti are also suitable to be bottom watered.

It also works well with hungry, fast-draining soils and situations where the plant's roots may not be easily accessed by a standard overhead watering technique. When bottom watering your plants, use room temperature water and pour it into the saucer under the pot.

Bottom watered houseplants should be allowed to sit in water at least once a week so their root systems can drink up as much water as they need. Empty all standing water from the bottom tray every three days or so to prevent bacteria and fungus build up and to promote healthy root growth. If you notice molds growing on top of the soil , bottom-watering might not be appropriate for your plant.
