I think my newly purchased Peace Lilies are overwatered and wilting. I also suspected cold damage, even though in Los Angeles, I left them by the window sill where it's no colder than....50F degrees? I'm not sure about the cold damage because I have 8 pots, and 3 are just fine. I watered them differently so I'm sure the wilting pots are overwatered.

What confuses me is.... none of them are yellow, non are brown, none appear damaged in anyway, and I don't notice any spider mite bites. I did prune away the flowers a few days ago. Again, the other 3 surviving pots also have all their flowers cut.

Before, the leaves felt sturdy. Now they feel like moist paper towels and droop...and now they look like bok choy. I took them away from the window, left them in a closet with a crappy white LED bulb shining about 6 feet above... and a heater about 5 feet away set to 80F, but the thermostat never goes above 71.

Are these guys going to make it?? I started geeking out about gardening a few days ago...I CANT LET MY FIRST PLANTS DIE!!!

I don't think the temperature range you state has had any effect. Cold damage means frozen tissue (32 degrees). Can they have frozen?
Peace lily is a plant that wilts easily when dry, recovers when watered, but usually gets yellow leaves when that happens. I have not known one to wilt while there is enough moisture. They LOVE moisture.
My rule with these is keep them moist all the time. Do the wilted ones feel as heavy as the unwilted ones? Add water to ONE of them, see if it recovers.
Sometimes water runs through and drips out because it did not soak into the soil.Make sure the pots feel heavy after watering.

Peace Lilies are pretty hard to overwater unless you move them into large pots with lots of soil that retains too much water. Temps of 50 degrees are not sufficient to cause cold damage.

Yellow leaves tend to occur when a Peace Lily wilts due to getting too dry. Soft, mushy leaves are symptoms of either cold damage or root suffocation.

If the soil is damp and the wilted leaves do not perk up, then you can be pretty sure the roots are severely damaged by either over watering or possibly cold if it was a lot colder than you indicated.

Any permanently wilted leaves will not recover so they can be trimmed off. If it is cold damage, then you should see some healthy new growth pushed out by the roots. If the roots have suffocated from staying too wet, then the plant is not likely to recover.

Why a closet? They do best if within a few feet of any window. Even if they were previously exposed to cold, they don't now need very warm temps. Anything above 60 degrees F. is fine.

Photos would be helpful.

so... it seemed they were underwatered and i tried dousing the pot in water. within 2 hours they started to stand up!! several hours later they looked to be back to normal.

thanks!

We have recently moved but our peace lily leaves are starting to turn yellow any idea what we can do

@Twopennies - Your Peace Lily may be reacting to the change in light. In the photo, it looks like it may be a bit too far from the window. Try your best to duplicate the light it received previously. Otherwise, provide lots of bright indirect sunlight.
