why is my rose hair tarantula digging a hole?

[darkness975]

My rose hair dug a hole that I don't think is stable it has a plant above it. when she's not in it can I collapse it or should I leave it

Is it a plant in a pot or a plant that is planted in the substrate? Or is it an artificial plant?

My G Porteri dug this really deep hole (2 or a little more inches) deep in a corner. I had no idea why for months as it did not seem she used it for anything. Then, one day last week I saw a bolus in there. I got it out and to my surprise, I pulled another, and another, and another... 6 bodies I had no clue where they had gone until I found the mother load in her garbage hole.
