Refresh, Replant, and Reinvigorate Your Garden Before Winter
Late fall is the perfect time to give your garden some attention, especially when it comes to long-lived perennials like daylilies, hostas, and irises. Dividing these plants before winter helps them thrive and gives you more blooms to enjoy next spring. At Whitney’s Farm, you’ll find everything you need for healthy, successful divisions, including Espoma Bulb-tone and Bio-tone Starter Plus.
Why Divide Perennials in Late Fall
After several years, many perennials become overcrowded. You may notice fewer blooms, smaller leaves, or clumps that have simply grown too large. Dividing them rejuvenates the plants, improves air circulation, and lets you fill other areas of your garden.
Late fall, when the weather is cool and the soil is still workable, is an ideal time to divide. The plants have finished their growing season and can settle in before the ground freezes.
How to Divide Daylilies, Hostas, and Irises
1. Lift the Plant
Use a spade or garden fork to dig around the root ball. Gently lift the plant from the soil, keeping as many roots intact as possible.
2. Separate the Clumps
For daylilies and hostas, slice through the crown with a sharp knife or spade, dividing the root mass into smaller sections with at least three healthy shoots and good roots.
For irises, pull apart the rhizomes and discard any old, woody, or diseased sections.
3. Prep and Replant
Mix Espoma Bio-tone Starter Plus or Bulb-tone into the planting hole. These organic, slow-release fertilizers contain nutrients and beneficial microbes that help new divisions establish strong root systems before winter.
Replant each section at the same depth it was originally growing, water well, and add a light layer of mulch to protect the roots from freezing.
Whitney’s Tip: Share the Beauty
Fall divisions make wonderful gifts for gardening friends and neighbors. Label your new plants before winter so you’ll know what’s where when spring returns.
FAQ: Dividing Fall Perennials
Q: How often should I divide my perennials?
A: Every three to five years is a good guideline. Some fast growers, like daylilies, may need dividing more often.
Q: Can I divide plants if frost is coming soon?
A: Yes, as long as the ground is not frozen. Water well and add mulch for extra protection.
Q: What’s the difference between Bulb-tone and Bio-tone Starter Plus?
A: Bulb-tone is designed for bulbs and flowering perennials. Bio-tone Starter Plus is ideal for new plantings and divisions, as it contains beneficial microbes that encourage rapid root growth.
Dividing perennials in late fall is one of the best ways to keep your garden healthy and productive. With a little time and the right Espoma products from Whitney’s Farm, you’ll enjoy stronger, more colorful blooms next season.
