Our perennial plants are entering their natural dormancy phase. As part of this process, foliage and blooms are browning and dying back—this is completely normal! We give the plants a hard trim in our greenhouse to support them as they conserve energy for the next growing season. Rest assured, your perennials will wake up and thrive again when it's time in your growing zone. Dormancy is how they prepare for a healthy, vibrant comeback as the seasons change!
Care: Clean away any dead foliage after frost. Fertilize with Proven Winners Continuous Release Plant Food in spring.
