August is an excellent time for gardeners to divide and replant perennial plants. Dividing perennials helps to rejuvenate plants, control their size, and propagate new plants for free. In this article, we explore the top five perennial plants that thrive when divided and replanted in August.
1. Hostas
Hostas are popular shade-loving perennials known for their lush foliage. They can be divided every few years to maintain their health and vigor. The best time to divide hostas is in late summer, around August, when they are actively growing. Carefully dig up the clump, separate the rhizomes, and replant them in shaded areas with well-draining soil.
2. Daylilies
Daylilies are hardy, low-maintenance perennials that produce vibrant flowers throughout the summer. They multiply rapidly and can become crowded, making August the ideal time for division. To divide daylilies, dig up the clump, separate the fans, and replant them at the same depth. This promotes stronger growth and more blooms in the following season.
3. Sedum (Stonecrop)
Sedum, or stonecrop, is a drought-tolerant succulent perennial that benefits from division in late summer. Dividing sedum encourages bushier growth and prevents it from becoming leggy. To divide sedum, gently lift the plant, cut into sections with roots attached, and replant in well-draining soil. Water thoroughly after replanting.
4. Astilbe
Astilbe is a shade-loving perennial with feathery flower plumes. Dividing astilbe in August helps maintain its health and promotes larger flower clusters. Carefully dig up the clump, divide it into sections with roots, and replant in shaded, moist areas. Keep the soil consistently moist to support new growth.
5. Echinacea (Coneflower)
Echinacea, or coneflower, is a popular pollinator-friendly perennial. It can be divided in late summer to encourage bushier growth and more flowers. To divide, dig up the plant, separate the root clumps, and replant them at the same depth. Echinacea prefers full sun and well-draining soil for optimal growth.
Conclusion
Dividing and replanting perennials in August is a rewarding gardening practice. It helps keep plants healthy, promotes vigorous growth, and provides an opportunity to expand your garden. Always ensure proper watering and soil conditions after division to support successful establishment.
