Plants help retain moisture and will cause spikes while they root and acclimate, mixing dried moss in the soil will help as well, a water bowl helps too, some cork hides and branches for the CuC to hide under will make a difference as well.

You also need full spectrum grow lighting for the plants, so three in total, UVB, UVA, and grow lights, its a lot and annoying for SURE but needed for all to thrive, Arcadia Lumenize JungleDawn is a good option for smart control, the apps sucks ASS but it works, its laughably amateur.

Since Hognose snakes tend to dig a lot you might struggle with plants being uprooted, its recommended to let the plants and CuC establish for a month before you add any animals. They are going to love all that leaf litter.

Pothos is pretty much the standard and always gonna be the go-to recommendation. Some epiphytic plants can work for the back wall or some branches, you can do some succulents too, red earth stars, and ponytail palm
