Frogspawn / hammer growth

[Hondatek]

This may be a stupid question. I have frags of frogspawn and hammers that are not on any frag plugs. I basically just stuck the skeletons in between a pair of rocks. My question is when they grow will the growth push the rocks they are between out or will they just grow around them ?

I definitely don't want them to grow and cause a rock slide . Thanks.

Is your on like a stem looking like a tree?

No they are not. They are definitely wall hammers. And the frogspawn is a few heads on a 1 inch tall skeleton.
