I bought these at Home Depot and was wondering if any of these are safe to put into my Sulcata’s terrarium? Idk if my tortoise would eat them, but in case they do would it be harmless?
Yes and no.
Succulents are mostly edible. But those small potted Succulents are treated with systemic insecticide that takes a very long time to go away.
IF you buy these. Re pot them after washing the roots and use new potting soil. Then wait at least a few months and only feed new growth.
