We already know perennials need to be divided but the where and when is probably in question. Check below for some tips and tricks.

When to Divide

While you can divide most perennials any time from spring to fall, those two seasons are best. This is because dividing your perennials can be stressful on the plants — and they'll recover better from the shock in cool, moist conditions. That said, if you want to divide your favorite perennials in summer, be sure to keep them well watered afterward.
As far as your plants go, wait to divide them until they're large enough that you can make several clumps out of them.

Step 1: Dig the Clump

Dig up the clump of perennials to be divided by inserting the shovel deep into the soil around the perimeter to loosen roots and isolate the clump.
Here's a hint: Watering the perennial a couple of days before you dig it will soften the soil and save you effort.

 

 

 

 

Step 2: Remove the Clump

 

Force your shovel or garden fork under the root ball and lever the ball up and down to loosen and position it on the shovel. Then lift the shovel and root ball. Try to keep the root system as intact as you can.
Once you dig the plant out of the ground, shake, wash, or brush any excess soil from around the root ball. This makes it easier to pull the clump apart.

 

 

 

Step 3: Separate the Crowns and Replant

Pry or cut apart individual crowns. Each clump needs to have sets of leaves and roots in order to grow.

Then replant the divisions promptly so the roots don't dry out. Plant at the same depth as before and water well. Cover the soil with mulch to help conserve moisture while your new divisions become established.
