Our team is working on the reintroduction of a species endemic to cracks in rocks of shoals. The water does eb and flow but stays generally wet. Has anyone tried glues to help plants establish within rocks? Our current collection is robust, has a large root mass grown in beds compared to in situ material that is essentially “bonsai-grown” in small rock cracks. We will re-grow this material to establish at younger, smaller size. But is there a glue or some sort of material that can help the plant material “stick” or “puddy-in” to the rock?
