March is the perfect time for gardeners to divide and transplant perennials, giving them a fresh start for the growing season. Proper division helps maintain healthy plants and encourages vigorous growth. Here are the top five perennials to focus on this March.
1. Hostas
Hostas are shade-loving perennials known for their lush foliage. They thrive when divided every few years. In March, before new growth begins, dig up clumps, and carefully separate the rhizomes. Replant the divisions at the same depth, ensuring they have adequate space to grow.
2. Daylilies
Daylilies are hardy and adaptable, making them ideal for division in early spring. Use a sharp spade to lift mature clumps, then split the root ball into sections with multiple fans. Transplant the divisions into well-drained soil, spacing them appropriately for future blooms.
3. Sedum (Stonecrop)
Sedum is a drought-tolerant perennial that benefits from division in early spring. Carefully dig around the clump, lift it out, and divide it into smaller sections. Replant these in prepared beds, ensuring they are not buried too deeply. This encourages healthy new growth.
4. Shasta Daisy
Shasta daisies bloom beautifully in summer but need dividing every few years to maintain vigor. In March, dig up the clumps, split them into sections with roots attached, and replant. Choose a sunny location with well-drained soil for best results.
5. Peony
Peonies are long-lived perennials that can be divided in early spring before they start to grow actively. Carefully dig around the root ball, lift it out, and cut into sections with at least three to five eyes (buds). Replant immediately, ensuring the eyes are just below soil level.
Tips for Successful Division and Transplanting
- Use clean, sharp tools to prevent disease.
- Water the plants well before and after dividing.
- Choose a cloudy day or early morning for transplanting to reduce stress.
- Apply mulch around new divisions to conserve moisture and suppress weeds.
Dividing perennials in March helps ensure they establish well for the upcoming growing season. With proper care, your garden will flourish with healthy, vigorous plants all year round.
