4. Prepare Soil
6. Mulch and Water
Dividing your existing perennials can be a great way to save some money on your landscaping. Or, increase the number of individual perennial plants in your garden by separating your mature plants. Either way, you can't go wrong with plants that continue to bloom year after year and spread.
Water the plant you will be dividing and the area surrounding it very thoroughly a few days before you dig. This will make digging the plant out much easier.
Dig completely around and under the root ball and lift it out of the ground. Be sure to dig wide enough as not to damage the roots.
Depending on the type of plant, divide your perennials in either spring or fall when the
temperatures are not extreme.
Some of the best perennials to divide in the spring include:
- blanket flower
In the fall, divide:
- bearded iris
Throw the whole clump onto a tarp and shake off the excess dirt, again being careful not to damage the roots.
Often the plant will divide naturally into sections. However, you may need to use spading forks, a saw, pruning shears, or hatchet to divide stubborn plants.
Mix some Miracle-Gro® Garden Soil for Flowers & Vegetables with the excess dirt from the original root ball (which you gathered on the tarp). The enriched soil contains the right amendments and plant food to help the transplants get off to the right start.
Plant the newly divided perennials at the same depth as the original plant.
To help prevent transplant shock, add Miracle-Gro® Liquid Quick Start® Plant Food when you replant the newly divided perennials.
To retain moisture, mulch your new plants and continue to water them over a period of days until they are established.
As additional perennial plants mature, repeat process.
After your divided perennials have established themselves, you can repeat the dividing process the following year.
