Most of the traditional peonies can be supported using a tomato cage and I make sure to place the cage over the peonies just before the foliage and stems emerge in the spring. If you have taller peonies you can use the very tall tomato cages made for indeterminate tomatoes. Now if you have floppy flowers you may want to just corral them upright with a perennial metal support system. A company called Gardeners Supply sells these and other plant supports online at gardenerssupply.com . Keep growing, Marianne Binetti
