You are probably right about overwatering. It's a very hardy plant, so if the soil is only a little bit too moist, just let it dry more. If the soil is soggy, repot with a fast draining cactus mix, not a potting mix with lots of peat. When you water, take the pot out of the dish and let the water run out the hole in the bottom. It should not be sitting in a dish of water. I have them outdoors in the ground where they thrive with almost no care at all and they're easy to start with cuttings.

Thank you for your response. The soil is not soggy, but definitely moist. I will follow your recommendation and let it dry some more. Thanks again!

In case you don’t know, you can test for dryness using a wooden skewer inserted into the soil for a few minutes. When you pull it out if it’s damp, don’t water. Even if it’s dry you could wait a few days. Is it getting plenty of light there?

After you water and let it drain, you could sit it on a stack of newspapers for a few hours and you’ll be surprised at how much water can be wicked out that way.

Like the wooden skewer tip. Thank you! Yes, we get indirect sunlight. Just cloudy today.

Too wet would be my guess also - definitely do not leave it with water sitting in the saucer for extended periods. Typically succulent house plants like this need much brighter light than is usual in most household interiors, some watering in summer and darn little in winter.

It probably needs more light. If there is any way to move it outside and slowly transition into at least some direct sun each day, it would love it. Or maybe a place in your home in some direct sun. Mine are outside in full sun all day, in the ground. They can take a lot of sun.

These are very drought tolerant full sun plants. We have some in the ground that go through an easy 6 months of 90-100f heat, full sun, and zero precipitation.

However, if given good drainage and full sun, you can grow them pretty fast with a good amount of water.
