Have you ever tried to transplant Adenium (Desert Rose) from soil into LECA.
Yes - it works well.
1. Choose a small grow pot because we want the plant to dry out quickly.
2. Careful with the water. Just run water through the pebbles at the sink once a week or so. Return plant to outer pot with no standing water at the base.
3. These plants don't support many leaves so no worries if it sheds leaves - they will grow back.
4. Desert Rose need lots of light with some direct sun. Partial shade outdoors though.
