Hostas: These shade-loving beauties are perfect candidates for splitting, especially since they tend to multiply rapidly. Before splitting, water the hostas and prepare new planting area.

Keep the newly divided hostas well-watered and monitor for stress, they may look a bit sad in the beginning but are quick to perk up.
Daylilies: With their stunning blooms and resilience to various conditions, daylilies are ideal for division.

When to Split Perennials
The best times to split perennials is usually early spring and fall. These seasons offer cooler temperatures and moist soil conditions, ideal for minimizing stress on the plants. While you can technically split perennials anytime during the growing season, it’s best to avoid extreme heat or drought. By timing your splitting efforts to coincide with early spring or fall, you give your plants the best chance for success and ensure a thriving garden.
How to Split Perennials
Prepare the Soil: Before splitting, ensure the soil is well-drained and amended with compost to provide nutrients for the newly divided plants.
Digging and Dividing: Carefully dig around the perimeter of the plant, lifting it from the ground. Use a sharp knife or shovel to divide the plant into smaller sections, ensuring each division has healthy roots and shoots.
Replanting: Place the divided sections in their new homes, ensuring they’re at the same depth as they were previously planted. Water thoroughly to settle the soil and reduce transplant shock.
Post-Split Care: Keep newly divided perennials well-watered, especially during the first few weeks after transplanting. Mulch around the plants to conserve moisture and suppress weeds.
