1st year take nothing cut off any flowers as they take away from the roots, cut them all the way to the ground............2nd year take a few, 3rd year take 8 to 10 weeks. In the fall clean it off...........take any ferns off, put composed horsemanure on top, mulch again in the spring to keep weeds down. If you live where it goes under 32 or less, cover with hay to protect the roots or they can die off.
