For healthiest plants, don’t crowd them and provide them with some air circulation around plants.  In spring, thin out new growth leaving 5-7 of the tallest, strongest stems and add a layer of compost around plants.  Deadheading will encourage re-blooming.  Clumps should be divided every 2-3 years for optimal vigor.
