Q: What do self-watering pots do?

A: The water reservoir supplies a consistent moisture level to the potting soil, ensuring that the plant roots have direct access to water through the adhesive force of the capillary action. The plants have the perfect level of water, and healthy root growth is easily achieved compared to normal pots.

Q: How long do self-watering pots last?

A: The refilling of self-watering planters varies depending on the size of the reservoir. While some self-watering pots require you to refill after two weeks, some can go up to four weeks without needing a refill. Most of the planters come with a water indicator that shows the level of water.

Q: How often do you refill self watering pots?

A: The number of times you’ll need to do so will depend on the type of plant, sunlight levels, and time of year, but it’ll usually be every three weeks or so. In between refills, Bullene says you can continue to water the top of your plants lightly every so often to raise humidity levels around their leaves.

Q: How do you add fertilizer to self watering pots?

 A: Fertilizing. Fertilizing your plants in a sub-irrigated vessel is easy when you use a liquid low-grade organic fertilizer. Follow the dilution directions on the fertilizer package and pour directly into the planter reservoir. The plants will absorb the nutrient-rich water as they drink.

Q: How do I know if my flowers need more water?

 A: Knowing when to water flowers in hot weather or times of drought can be tricky. If you feel your flowers aren’t getting enough moisture, check the top 3 inches of soil. It should be consistently moist. You may need to increase your watering schedule to maintain moisture.

Q: Can you overwater plants with self watering pots?

A: It is unlikely that a self-watering planter will cause root rot. Root rot is caused when the plant has been overwatered and the excess water doesn’t have a place to go — such as in the bottom of the pot away from the roots or out a drainage hole.
