Dividing Perennials In The Fall – The Simple Keys To Flowerbed Success! 

Many perennials can be divided in fall when it's cooler and they're preparing for dormancy. Split perennials 4-6 weeks before the first forecasted frost in early to mid-fall.  


Choose vigorous perennials to divide. Find overgrown, flowerless, or densely foliaged plants.  


Wet perennials a day or two before dividing. It hydrates plants and makes lifting them easy.  


Use a sharp garden spade or shovel, a garden fork, pruners or a knife to remove thick roots, and pots to store the divided perennials.  


Dig around the perennial clump to loosen and lift it. Gently separate roots and divide plant using a garden fork. Each division needs strong roots and multiple stems.  


Spacing each separated plant section in your flowerbed or garden by mature size and growing propensity, dig holes. Plant the divisions at the same depth and firm the soil around the roots to remove air pockets.  


Water divided perennials well after replanting to soften soil around roots and reduce transplant shock. Keep soil moist but not soggy for weeks following division to stimulate root growth.  


Mulch newly divided perennials' bases to keep soil moist, minimize weeds, and insulate roots in winter.  


Watch divided perennials for stress and dehydration, especially in dry months. Remove and water dead or yellowing foliage.
