My Arabia and Arbeita die out in the centers each winter when they get bigger. I am thinking that after they bloom around the edges I would dig them up and cut into pieces and pot to report in fall. I have done it before with mixed results. They are hard to keep the roots clumped. Will water well before digging. Any suggestion on a liquid or otherwise fertilizer that would enhance the project. They are always early to bloom, among the first so I move them throughout the garden edges. Very prolific here.
