What is the correct way to grow string of pearls succulents?

It likes to dry out between feedings, and it likes sandy soil similar to what cactus would grow in. If you are in a humid area or it is getting rained on often, that may be your problem. Good luck.

I bought some a few weeks ago off of Etsy, and they are doing well. The seller suggested a certain kind of soil, which I bought at Lowe's. I live in the hot, humid, south, and I keep them under the patio so they can get afternoon sun, but only about 4 hours. I sprinkle with water every few days. I bought 3 other kinds at the same time, and all are doing good.

One thing I did do was put some of the fertilizer spikes in the pot, halfway between the plant and the pot edge. I put the plants in hanging pots. Maybe that helped?

Thanks for the suggestions. I might be overwatering or using incorrect soil. It's so frustrating because I really like them! I will try again using all of your tips. Thanks to all that responded.
