I'm curious if cutting them back will diminish their ability to survive winter. I believe zone 6 where I live is typically listed as their hardiness limit. How do you manicure yours? At what time of year?

I have 4 clumps of them, and went ahead and cut one back as an experiment. The leaves are partially brown and limp, except close to the crown, where they're still green and turgid. They look really nasty right now, and I'd prefer to whack them way back, but not if it means risking losing them.

I twist mine up and make a bun with it. I read to do that to protect the crown. Then in the spring I cut it all off

Good to know!

Now that mine are cut back I think I'll load it with the long pine needles. Glad I didn't use all of them already.

Jennifer, that's a great idea! And that will get all that mess out of the way so I can work around it, right now it looks like a dead octopus out there- the leaves look like tentacles.

Mine would be jealous if it saw how nice and cozy both of yours look. Great job, Jennifer. You're a good plant mom.

In spring how low do you cut them back - an inch or two?

Neal > I used to clean and cut mine in early spring. I guess leaving them all winter was a sort of natural mulch.

In my area my Kniphofia sarmentosa is actively growing in winter, and blooms in late winter. I tend to do my trimming in late Spring when it starts to rest.

Mine is a winter dormant variety. After mine is finished blooming I cut any remaining flower spikes off, then leave it alone for winter. I don't remove any dead leaves because they are good insulation. In early Spring I use a hand rake and pull all the dead leaves out, dragging the rake through it like combing hair Smiling It seems to love that and it cleans it up nicely without having cut off leaves spoiling the cascade.

Sunlover, I also did the same. Its easier in spring when much of the leaves are dry.

Just a photo of my Kniphofia sarmentosa right now..lots of growing in my area during winter, hopefully it will try some blooms in mid to late Feb, so any cutbacks I do will be in late Spring.

Those leaves are tough, I felt like they'd hang on if temps stayed above 20F. The clump I cut off has grown a little through winter.

Just saw this morning, my Kniphofia sarmentosa is starting to make its flower spike: on cue to its usual flowering time.
I thought I just got one, closer look there were two: Smiling

Today I cleaned up the 3 clumps of Kniphofia that still had leaves attached, and thankfully the leaves pulled away easily and the crowns underneath look healthy. However, the clump that I trimmed back in the fall looks like it may be dead. It may surprise me, but the crown looks dark and its kinda slimy in there.

I'll look tomorrow. I was just outside and the wind is frightful.

Good luck with yours, Neal.

Not a big deal if the one clump is dead, still have 3 other large clumps, and I do have Roses on the way soon, so that spot may just be destined for one of those.

That's almost a guarantee that the plant will survive and thrive.
