I HAD A CLUMP OF JOAN SENIOR FOR YEARS
AND ONE YEAR THE ENTIRE PLANT DIED EXCEPT FOR ONE PLANT WHICH WAS WEAK BUT GREW INTO A STURDIER PLANT BUT DID NOT BLOOM. OVER THE SUMMER IT DID WELL BUT NEVER INCREASED.
THIS IS AN OLDER VARIETY AND MAY NOT BE KNOWN BUT I WAS WONDERING IF THIS IS TYPICAL OF THIS PLANT.

I have one that is 10 years old, seems just fine. I was thinking of moving it next year because it is being crowded by some nearby plants.

I had 'Joan Senior' for a few years but it did not like the soil pH here, not acidic enough.

I have grown 'Joan Senior' for more than 20 years with no problems. Our soil is supposedly basic - Rhododendrons do not grow well here.

Might yours have suffered from spring sickness and died back?

No it did not have spring sickness, but it did get interveinal chlorosis indicating it had a problem with the pH (which was likely around 6.8).

I have had Joan for about 5 years or so & she has always bloomed except for this past summer. We had extended drought conditions & with having to water so many plants I just didn't get any to her. She did not bloom. Not sure what will happen next summer.

I don't have Joan Senior but have had happen what you describe on rare occasions. Becky Lynn grew well for me for many years. One year it almost disappeared. I'm not sure why. It barely hung on for a couple of years with maybe one stunted bloom. But this year it increased and bloomed fairly well. Maybe just give it time and some extra water/fertilizer next year.

sometimes I have dl that pull themselves down under the soil line and they die and a tiny one will grow back. I had a lot this year that pulled down like that. Some of them I lifted, some I still have not gotten to. If they are left like that the whole clump can die. I don't know why they do it, but it sure is a pain Thumbs down I can tell which ones have did it because the foliage all starts to look streaky or light colored.

I have had Joan Senior for 20yrs it is planted under a cherry tree and is always has plenty of blooms in my yard. Never have had any trouble with it. I hope yours comes back for you.

I grow most of my daylilies in pots but Joan Senior has been in the ground in full hot Oklahoma sun now for well over a decade. She has always grown and bloomed well. About 3 years ago she surprised the heck out of me by reblooming not just once but twice. I don't get many rebloomers here, and certainly never Joan. The next year I divided her pretty hard and although she's still blooming she hasn't recovered as well from that dividing as I had hoped. This years monsoon rains didn't help either. I have a feeling I shouldn't have divided her as hard and will have to have patience to get her back to her previous glory. BTW, our unamended ph ranges from 6.8-7.2 and it doesn't seem to affect my in ground daylilies at all..........Maryl

I have had 'Becky Lynn' for more than 20 years, 17 of those growing in the same location. It has not had any noticeably severe problems. Might what happened to your 'Becky Lynn' that year have been an incident of spring sickness?
