Getting rid of daylilies
Peter Ash
I have a large patch of old daylilies, the common orange one. I would
like to clear out the patch, and put in new varieties. I would like
to get rid of ALL the old ones, otherwise I won't know whcih are old
and which are new until they bloom.
Over 2 seasons in zone 7 I have tried three goes w/ Roundup, black
plastic for two months, clear plastic (solarizing) for two months in
mid-summer, hand weeding, rototilling, covering w/ 10 thicknesses of
newspaper, but I'm still getting H. flauva (should be renamed H.
indestructibilis) back. Any thoughts?

I had a nearly identical experience. It took two seasons before I was
convinced that they were really eradicated. It probably was made
worse by rototilling since even the tiniest root fragment can generate
a new plant. All I did, which finally worked, was be persistent.
Solarizing followed by hand weeding the straglers is what I did.
You might consider planting a cover crop like annual rye grasss to be
weeded out before being turned under next spring. At least then some
weeds would be inhibited and you'd be building up the soil. Another
alternative is a deep (6" or more) mulch, again followed by hand
weeding until it's clear, then plant the new plants in late spring.
Persistence is probably the only thing that will work.
If you space out the new plants properly and label them, it souldn't
be too hard to identify the small volunteers that appear in between.
Just be certain to remove every root fragment in the planting holes.
A minor correction. Hemerocalis Fulva is the common orange, called
tawny daylily. Hemerocalis Flava is the common lemon daylily.
Hope that helps a bit.

Daylilies are invasive. They are a real pain in areas that are to
be planted to native prairie species. As far as I have seen, the
best bet is the good old pick and shovel and remove every bit of
root and rhizome as you go along. It may take a while but this will
eventually clear them out.

I had the exact same problem in my side yard with some plants that
appeared to be daylillys but had not bloomed in the 20 years my
neighbor has lived there. I also tried everything that you described.
Last year I waited until they had come up then dug out the entire bed.
It is easier when they have grown out so that you can make sure that
you get all growing material out of the bed. This year there have
only been a few coming up mainly near where I couldn't did very well
such as close to the house.
Good Luck as it is a long job

Dig them up; it can't be any more work than everything else you've tried!

When you've got them dug, save the tubers. They're great eating. You can
deep fry them, saute them or use them in stir fries.
Make sure you get ALL those little tubers, tho. That's whence cometh the
new flava plants.

You could put an ad in the paper or a sign in your yard.
Daylilies- Free- You dig!!
I know if I saw the sign I'd stop. Then you save yourself from
having to do all the work. Many people love daylilies and to
purchase them can be expensive. give it a try!

I missed the original post but if you are in my area I'll come and dig a
few up - need more :) Have a hill that's a pain to mow. If you want to
dig and mail them I'll pay postage...
