I'm a bit puzzled about the concept of wicking in houseplants. I visited Lowe's recently and noticed that they wick all their houseplants, but many of them looked really sad and were completely soaked. Isn't it generally a good idea to let the soil dry out between waterings? How does wicking actually work, and what should I know about self-watering planters?

Whether or not wicking works really comes down to the type of plant you have. Some plants love constant moisture and do best in wet conditions, while others prefer to dry out a bit in between waterings. Make sure to check the needs of your particular plant to see what works best!
Yes, wicking definitely works! It relies on capillary action that helps water travel from a reservoir underground into the soil. However, if the soil is overly wet, like what you noticed at Lowe's, it likely means they've watered too much or the soil is too damp. Factors like wick material, soil composition, and the plant’s water uptake all play a role in how effective this is. I usually wick most of my plants without any issues of soil saturation.
Thanks for the detailed explanation! Does that mean the soil can stay consistently moist as long as there's water in the reservoir? Is that actually safe for the roots?
