Hi!
This is the clump of Stella in the garden.
It's blooming again, but many scapes are short and as you can see (I hope) flowers bloom inside the foliage.
I think it's about time to divide it, but I'm not sure. I bough the plant already in bloom, it was a small plant, and planted in the garden two years ago.
Thanks for looking!

That reminds me that my clump of Stella needs to be divided. My clump is larger than yours.

Sabrina - That is a very good question! I hope others here can describe how one would know that it is time to divide!

@sooby , @admmad , @Char , and anyone else, how to know WHEN to divide your daylilies?

If a daylily is no longer blooming as well as it did in previous years then it is time to divide it. If it is blooming only on fans near the outside of the clump then it is time to divide it.

In Florida, Munson advised that clumps should be divided every year in the fall. He probably had an eight to one or better increase ratio per year and so his clumps probably grew quite big in one year in his location and with his growing conditions (2 fans increasing to 16 in one year). He considered that the plants suffered if they were not divided that frequently.

I agree with Maurice. When a daylily has clumped up with a majority of mature fans and is no longer blooming as well as it did previously I would normally divide it. Remember though, sometimes a daylily can have a bad year. I have some medium clumps (8 -10 mixed sized fans) that really shouldn't need dividing yet that were poor performers this year. Could have been the hard winter, dry spring, ...

Thanks everyone, my Stella is reblooming, I can't easily distinguish how many fans it has, will check better later. It doesn't seem to have big problems, except for some white streaking on some leaf, and some leaves are thinner than others, and pods abortion.
I guess I have some nutrient deficiency going on, gave chelated iron to all DLs the past week and newer leaves seem to be better, but there are some other defects on other leaves. I had few blooms, almost none in one piece of garden but it's difficult to say why: the plan where all transplanted this spring (they were in pots before). we also had very dry spring and summer, with highest temps than the year before. So I'm really guessing at a lot of things!

Getting here late today, I would say that it's normal for Stella to rebloom low. It does that here anyway. Were the earlier scapes taller?

For the problem area, transplanting in spring may mean the daylilies don't flower this year but it varies.

The scapes were all above the height of the foliage, now many are shorter, I never noticed it but if knew about this it means it's normal, I guess.

I thought about transplant and no blooms, so I will wait next year to judge. Some fan remained very short and small, so I guess there's been a sort of shock. Only two bloomed, one put up two scapes too big for the size of the plant and the other a little and short scape with one flower and then decided it was enough LOL!

That's what Stella does here, the early blooms are above the foliage but not the later ones. Maybe the foliage grows after the first flowers and then it obscures the later scapes, or maybe the later scapes are just shorter. I've never paid much attention because it doesn't put on much of a show later anyway. 'Happy Returns' does the same thing. One year I actually trimmed the foliage shorter on it so that the next round of flowers would show above the leaves, but it was a lot of work carefully cutting around the scapes and I never bothered again

There are big clumps of daylilies in this area that I know have not been divided in at least fifteen years and they still bloomed prolifically this year but I wouldn't say that applied to all daylilies under all conditions. One thing I would say is that the bigger a clump gets the harder it is to dig up, so one might want to divide before flowering decreases in that case.
