Self-watering pots for succulents and houseplants

Updated: October 2026

The title on the pot says it suits succulents, a snake plant and herbs in the same sentence, and you already own a cactus that rotted the last time the compost stayed damp. A self-watering pot keeps the lower compost moist by design. That helps a thirsty aroid. It is a poor way to keep a cactus, a succulent, a snake plant or a ZZ plant, which need the mix to dry. The listings are the twelve on the [self-watering planter comparison](/hub/plant-accessories/self-watering-planter). Products Compared did not run a rot trial.

Why the lower compost stays damp

A self-watering pot is a reservoir plus a path upward. A cotton wick, a fabric strip, or the legs of an inner pot keep water in contact with the bottom of the compost, so the lower mix stays damp whenever the tank has water in it. The top can look dry while the base is still wet. The British Cactus and Succulent Society makes that point about peat compost. Homes & Gardens calls a consistently moist mix a poor way to water cactus and succulents, because it raises the risk of rot. GrowTropicals adds the practice that makes a reservoir tolerable for thirsty plants: let the tank run empty so air re-enters the compost. “Let it dry” means the reservoir for a few days, not a month without any water.

Plants to keep out of a wick pot

Keep cacti, succulents, snake plant and ZZ plant out of a pot whose job is steady moisture. GrowTropicals names those four. The WSMKSZ 25 cm pots, three for £25.99, are a plausible size for a monstera that likes moisture. The snake-plant line on the same bullet does not change the wick. Fayavoo’s herb boxes name cactus and snake plant beside herbs, while UK reviewers of those boxes talk about basil, not a cactus thriving. Herb choice stays on the windowsill herb planter page. A ZZ in a dim room is a different decision, in a ZZ plant in a dim British room.

Plants that match a reservoir

UK reviews use the yarlung 12.7 cm pots, £16.99 and 4.3 from 650 reviews, for anthuriums and alocasias in pon. Yimomoyi reviews mention the wick with semi-pon, if a mesh stops the substrate falling through. Pon and leca are not the same as a cotton wick in compost. In the UK reviews they are a mineral substrate in a nested pot. The float on the yarlung pots sticks in several UK reviews and shows the wrong level until you shake it. That is an indicator fault, not proof that pon fails. Let the reservoir run dry before you refill, including for an aroid in pon. A holiday of a few weeks is what one Skelang reviewer managed with a long trough, not with a 12.7 cm pot.

What to do with a listing that says both

A cactus, an aloe, a snake plant or a ZZ should stay in a free-draining mix, or you should not buy the wick pot. The yarlung six-pack is the small pot UK growers in this file use for aroids in pon, with the stuck-float limit. The WSMKSZ 25 cm pots are the size for one larger moisture-loving plant. The Lechuza trough at £45.87 is the balcony box, not a succulent planter. INTERWARM’s clear pots name succulents and have two French reviews, so they are not a UK succulent result. If you do buy a reservoir pot, the how to use a self-watering planter page is the set-up: wick in the compost, water in the reservoir, and a look after two or three days.

Common questions

Can a cactus live in a self-watering pot?
A cactus is a poor fit for a wick that keeps the lower compost damp. Homes & Gardens and GrowTropicals both say a consistently moist mix raises the risk of rot for cacti and succulents. Use a gritty mix in a pot with a drainage hole, and let that mix dry.
What about a snake plant or a ZZ plant?
GrowTropicals groups snake plant and ZZ with cacti and succulents: they need to dry out, and a permanent wick works against that. They often look unchanged until the base rots. WSMKSZ names snake plant on a 25 cm wick pot that is a better match for a monstera. Fayavoo names snake plant on a herb box. Neither bullet is a reason to put one in the reservoir.
Which of these pots do people use for aroids?
UK reviews in this capture use the yarlung 12.7 cm pots for anthuriums and alocasias in pon, and for orchids. Yimomoyi is mentioned with semi-pon. Skelang’s longer troughs are mentioned for crawling aroids. Those uses still need the reservoir to run dry between fills. The yarlung float sticks, so you check the water by eye.
Should the reservoir stay full?
No. For a houseplant, let the reservoir empty so air gets back into the compost, then refill. GrowTropicals states that pause. Lechuza’s 2–10 days after the minimum mark is for Lechuza planters, and a hot day can remove the pause on a BALCONERA.
Is pon the same as a cotton wick in compost?
No. Pon and leca are mineral substrates. In the UK reviews here they sit in a nested pot with a visible water store. A cotton wick in compost is a different setup: the rope wets peat-free or peat mix from below. Both can keep the bottom damp. Pon is not a full method on this page.
