Too many Daylilies. Said nobody. Ever.
Probably the most known and common method of propagation is digging up the root ball and dividing the rhizomes. This can be done most anytime the plant is not in bloom. Ok, I admit, I have dug and divided them while in bloom but I can’t think of any reputable garden source that recommends this method! Generally, most sources suggest tackling this task in fall or early spring.
1. Dig up the clump
2. Divide by pulling or cutting apart the root ball
3. Trim as needed, replant or share.
Another, lesser known, method is to harvest the proliferations. After the daylilies have finished blooming and before the stalks turn completely brown, it’s a good time time to check the scapes for proliferations. Cut any you find with about 2 inches of stalk remaining and pot them up. Don’t have any pots around? Put the ‘baby’ in a glass of water. Be sure to label them so you’ll know “who’s who” in the spring.
Keep them in a sunny window for the winter before transplanting them back into the garden come spring. This proliferation will be an identical twin to the parent plant.
In just a little time, you have increased your supply of lovely daylilies for your own garden or as gifts to your family and friends.
