I have a patch of daylilies that I dug up last week and potted into 1 gallon pots...3 plants per pot. I shook off the soil and potted them in a potting soil/peat mixture. I watered them well. After a few days each plant has leaves that are turning yellow and brown.. some of the flower pods are dying off as well. I used faucet water (chlorine problem?). Should I have kept some of the original soil around the roots? Could it have been shock? I'm baffled. Any help or advice for future potting of lilies will be much appreciated!!!

They may be reacting to the transplant, the roots being disturbed and-or the hot weather. This is one time of the year when I do not plant or transplant. Too hot down here. Do not let them get too dry for too long. Remember that dry summer winds can also make them loose moisture so keep the pots away from windy areas.

thank you for your fast reply. it has been quite hot the past few days. do they normally bounce back? how long does the yellowing last if it's just from transplanting?

They normally do. But it is hard "seeing into the future" to determine what exactly they will do. They may either produce new foliage now or, they may decide it is too hot now, or if they do not need as much foliage then they may produce more foliage in the Spring of 2020. Arrival of Fall temperatures may abort its plans to produce foliage in 2019 so.... just give them TLC. Do not overwater of course but do not forget to give them water either.

Did you take them all the way to bare root? If so, doing so during potting up causes the small roots die off. The fans are stressed because they cannot take up enough water or nutrients to support the foliage. Recommend cutting the foliage back to about 3-4 inches on all fans. This is a common practice with most when repotting, or getting fans ready for a shipment. They'll usually recover fairly quickly after doing so.

The photo below reflects what I am referring to, regarding cutting foliage back.

Are you saying you added extra peat to the potting soil or are you saying it's a peat based potting soil?

I agree with Stan, next time (or even now) cut back the leaves. What happens is that there is root loss when you dig and divide them but there is still the same amount of leaf demanding water. The problem is increased by removing the soil plus hot weather at this time of year. If you cut back the leaves now it may not be too late to save some of the flowers.

By 3 per pot do you mean 3 fans per pot?
