We live on a brackish river in south FL. The property adjacent to the river is landscaped with large rocks. We also have planted mangroves that we must trim to maintain our view. We have a small beach area, filled with white sand but we just don't use it and would like to plant it with no-care plants. We have 1 sea grape on the beach that must be trimmed. We'd rather have plants than add more rocks. My husband has MS and can't do any yardwork. Can you help?
