It's worked out well so far. More by accident than design, the two Azalea pieces 'lock' into the stonework - so both can be removed independently (and replaced exactly as before) if needed.Check that your hardscape is maintenance friendly
• I also have some small moss (Marimo) balls. Could I split them and glue to some of the wood or will that end in tears?
If done right, DS needn't take more than 2-4 weeks (some people limit light) - often it's just a case of flooding when convenient, even after a DS you should be prepared for frequent water change, attention to tank etcI'll be realistic with my patience levels though - I'll likely flood this within a month.
