As summer winds down, it’s the perfect time to refresh your landscape by dividing perennials. Dividing plants not only prevents overcrowding but also promotes better airflow and reduces the chances of diseases like powdery mildew or rust fungi. Additionally, dividing helps the plants access more nutrients, resulting in healthier growth and more blooms.
Dividing plants is an easy process. Water the soil deeply the day before to loosen the ground and give the plant plenty of moisture for transplanting. Aim to divide plants on a cool, cloudy day to avoid drying them out.
Use a spade or sharp knife to dig up the plant, then gently separate the roots or cut the plant into sections. Each division should have at least three healthy shots. Keep the divided plants in a moist, shaded spot until ready to replant.
Common perennials that benefit from fall division include peonies, iris, lilies, and salvia. Generally, spring and summer bloomers are divided in the fall, while fall bloomers are in spring. Keep in mind that some plants, like balloon flowers, don’t respond well to division and may not bloom for a few years afterward.
If you have a collection of randomly found plants, like my surprise peonies, you can give them to friends or replant them in a more suitable location. Dividing perennials is a great way to enhance your garden and share the beauty with others.
