In the last week my original one hyacinth plant has really grown. I would love to place some of the plants in other areas of the pond (Specifically looking to hide the pump). My question is do the plants divide on their own or do I need to cut/separate them. It seems like I could just cut them apart but I don't want to hurt the plants. I attached a picture with a red circle where I think I should cut them. Any advice is appreciated.
