11 Easy-To-Divide Perennials That Will Multiply Your Blooms
Want more flowers without spending more money?
One of the best gardening secrets is dividing perennials. Many perennial plants naturally grow larger every year, and dividing them allows you to create multiple plants from a single original specimen.
Not only does division give you free plants, but it also improves plant health, boosts flowering, reduces overcrowding, and fills empty spaces throughout your garden.
If you're looking to maximize your garden budget, these easy-to-divide perennials are the perfect place to start.
Why Divide Perennials?
Over time, many perennials become crowded.
When this happens, flowering often declines.
Dividing plants can:
- Increase flower production
- Improve plant health
- Reduce overcrowding
- Prevent disease issues
- Create free plants
- Fill new garden beds
- Share plants with friends
The result is a healthier, more vibrant garden with little additional cost.
