We like to get the most out of our gardens in every situation, and that means making sure that our perennials are in good shape. To keep our gardens looking amazing, we need to make dividing perennials a part of our yearly routine. A garden in which you take the time for separating plants is a healthier and happier place for your flowers and veggies.
When you divide perennials regularly, you ensure that your plants get the nutrition and growing space they need to thrive. Our guide helps you find the perfect plants for folks who wish to include splitting perennials into their gardening tasks.
In this article, you’ll get a rundown of flowers and grasses that will reward regular division with brilliant sights and delightful scents. We also give you some tips on dividing perennials so that you wind up with contented plants. Before long, your yard will be awash with a fireworks display of colors.
Perennials usually grow wherever you decide to plant them without needing much encouragement. The easiest perennials to grow are just a step or two up from weeds and will take to the soil no matter the time of year.
However, you can give your perennials a better shot at thriving if you take a few precautions. Most of them will take off and sprout like mad if you give them the right growing conditions.
When Should I Plant Dividing Perennials?
Try to plant your separating plants after the final frost of spring has passed unless you are planting seeds that require a freeze to start germinating. Check your local agriculture office for specific planting information that addresses your regional environment.
They’ll be able to give you a reliable planting timetable for your perennials. You can also get tips from them on how to get rid of grub worms and other pests.
How Do I Prepare for Splitting Perennials?
Your first goal when splitting perennials should be to get the job done early. Don’t wait until your perennials are overcrowded and unhappy. When you get ready for separating plants, you should look around for the best-looking perennials.
Dividing perennials when they are at their peak ensures that all parts of the division will be healthy and ready to grow. Make sure that the weather is cool, too, to help your plants bounce back more quickly.
Start by preparing the area. Clean pathways with a pressure washer to have a clear surface upon which to work. Next, select the number of plants you wish to divide and give them a thorough inspection.
Check them for damage caused by injury, nutrition issues, or pests. To make your workspace a more beautiful place to operate, consider placing some natural insect-repellent plants as a home remedy to get rid of gnats to make time in the garden more enjoyable.
What is the Best Method for Separating Plants?
When you’ve identified the splitting perennials you wish to divide, you should begin by loosening the earth with a garden fork. Then, dig at the drip line around the center of the plant with a sharp spade. That allows you to get all of the roots out without injuring the plants.
Make a trench around the plants until you have a whole clump of earth that contains the root ball. Once you have plants out of the ground, don’t let them dry out. Place them under some damp newspaper and in a shaded and cool container.
Take this opportunity to fertilize the soil in advance of your replanting to help your divided perennials do well. The rule of thumb is to divide plants into sections no larger than a quarter of the original plant’s size.
You might need to use a small sharp knife or spade to separate some woody or fleshy root systems. Try to divide by hand whenever possible to avoid traumatizing the plants. Spread the new divisions out, and give them lots of space to grow.

Bee Balm plants live up to their name and attract pollinators including bees, hummingbirds, and butterflies.
Try to pick a few Bee Balm flowers regularly to encourage additional growth. Keep the soil moist and well-fertilized for best results. Some pollinators attract cats and other small predators into your garden.
Fortunately, you can find lots of excellent DIY tips on how to keep cats out of your yard. Divide the Bee Balm plant in either the early spring or late fall.
