Wait until your daylily has made a large clump before splitting. Do not water the daylilies for two to three days before dividing them. The roots are much easier to pull apart, and the fans are less likely to break off in the dividing process, if the plant is dry. Dig up the clump keeping in one large piece.
Cut foliage back so that only four to five inches remain. also cut off all scapes. Long foliage and scapes rob the newly transplanted daylily of nutrients and water that it needs to recover from being dug up, divided and planted again.
Cut roots back so that only three to four inches remain.
Remove all dead foliage from plant.
Remove hair like roots that accumulate around the crowns of the fans.
Our plant with foliage and roots cut back, dead foliage and hair roots around crowns removed.
Now you are ready to split the daylily into small clumps of two or three fans each. Do this grabbing two clumps and twist and pull.
Twist and pull from side to side and back and forth. Normally you can split the daylily up into small clumps of two to three fans in this way. If you get to the point that no more fans break easily from the crown, but you want to divide further, give up on the twisting and pulling and get a sharp knife.
Cutting a clump with a sharp knife instead of twisting to separate.
Clumps separated by cutting with knife.
Our large clump now divided into clumps of two or three fans are ready to plant, sell or give away.
To plant, dig a hole deep and wide enough to hold roots. Make a small mound of dirt in the center of the hole.
Put daylily on top of mound and spread roots over the mound.
Cover roots up to the crown with dirt mixed with organic material (compost) to amend the soil. It is important not to plant your daylily too deep. The plant has a better chance of surviving if planted shallow.
