Your plant looks very thirsty, but it's certainly salvable.

The soil your peace lily is growing in looks very water retentive. That also means that once the soil dries out too much the entire soil will essentially become like a brick. That is, it becomes completely water repelling and any water you give it will simply run down the sides of the root ball and out the drainage hole (the pot has a drainage hole, correct?)

"About 3 or 4 weeks ago I noticed it was drooping and neither of us had watered it in a while"

I think that's what happened-the soil became too dry and became water-repelling.

I would take the entire pot, fill a bucket or sink with water, then submerge the entire pot into the water so the surface of the soil is submerged under the water. Bubbles will begin to flow out of the soil-that's just stale air being forced out from the soil by the fresh water pouring in. Keep it this way for maybe fifteen minutes, or until the soil stops bubbling. Then, I would put the pot back in its usual position and let the plant soak up the water.

If this works, I would then set about getting used to watering when the plant needs it-not on a set schedule (like "water once a week"). I would take a wooden dowel or chopstick, poke it all the way down into the soil, leave it for ten minutes, then pull it out. If the dowel is dirty/dark/obviously wet, withhold watering. If it comes out clean/light colored/obviously dry, water.

I just love peace lilies. I hope yours gets better!

Water the thing will you!!??? Quickly too...

Then water when al most dry, not to the point of wilt and by next spring you can plant it into a nicer mix! Water it..I'm almost scared it won't make it by he morning!!

Seriously, how long was it before you noticed it got this bad?

Thank you, goldstar135 for your detailed and helpful response! No jokes here Mr. Mike.. just an honest, inexperienced, peace Lilly owner looking for some knowledge and advice!

These need pretty consistent, frequent watering and yours got completely dried out.

I totally understand,.Was kidding..Been there done that..Good luck)) Please keep us updated even if you could tomorrow after a good watering...

Does the pot have a drain hole? It definitely needs one if it doesn't have one. Also, if it has a reservoir where water can be reabsorbed by the plant, you should remove the reservoir, put it in a saucer, and make sure it never sits in drained water.

After soaking the pot, let it drain until the dripping stops. Then prop it up so it's tilted at 45 degrees for maybe half an hour, which will remove more water. If the drain hole is in the center, set it upright again to see if even more drains out.

The top of a plant is usually what we care about, but the root system is the key to keeping the plant healthy. What few of us realize is that roots need oxygen from air, so we (and the people who sell them to us) pot our plants in conventional peat based potting soil that breaks down quickly into a dense water retentive mass that suffocates roots when it's wet. I suspect that's what your peace lily is planted in, and that its root system is compromised so that the leaves get wilty both when the soil is dry and when drowning or dead roots can't take up water when the soil is wet

If a good soak brings your peace lily back, follow goldstar's services about checking the soil to make sure it needs water before watering again. That will allow the roots to get at least a little bit of oxygen, but in the long run, you'd do well to consider removing the existing soil and replacing it with a faster draining, more durable, aerated mix that will support a strong healthy root system that will keep the plant happy and healthy for many, many years.

There's a ton of information on the forums about how to do this; you can completely geek out on the science behind it and how soil components work together. Some of us use extremely plant-centered mixes that require the very frequent watering that most plant. thrive on, but there are many variations that make compromises that greatly improve plant happiness without requiring work that some folks who want to help their plants can't quite live up to.

Thank you for all of your advice on how to save our peace plant! We ended up removing the plant and the soil it was in (it was all completely dried out, the roots and all) and replanted it using a new soil. We used the same pot, which does have a drainage hole. I watered the plant as soon as we replanted it this past Sunday and I've been watering every other day since. Look at the progress we've seen already! Most of the leaves still look wilted and dried out but I'm happy to see the plant standing up again! Any suggestions on how to get those leaves looking healthy again? Should we remove the leaves with the brown tips? Thank you!!

That's great news! What a tough plant!

What did the roots look like when you depotted it? Did you see healthy looking white roots, or were they all really dessicated? If most were dried up, the plant needs to grow new ones, which makes it doubly important that the soil contains air as well as water. Fortunately, even soil that's just barely moist provides a healthy amount of both. Just follow goldstar's advice to make that happen:

"If this works, I would then set about getting used to watering when the plant needs it-not on a set schedule (like "water once a week"). I would take a wooden dowel or chopstick, poke it all the way down into the soil, leave it for ten minutes, then pull it out. If the dowel is dirty/dark/obviously wet, withhold watering. If it comes out clean/light colored/obviously dry, water."

Keep us updated!

Pls. don't water it every other day, you'll drown the poor thing.

It can't be filled up w/ water so fast & made better.

Not only patience is required, but a bit of time btwn waterings so that it's slightly moist, not wet, to allow the plant to take in oxygen & breathe. If it's too wet it can't take in oxygen & will rot.

Karen is right..I was going to say the very same thing. I am assuming that many of those roots are dead and watering too often will rot them even further..Water only as needed and that means let your mix go almost dry before a good flush of fresh water again...I would not fertilize at all until you know your plant is in good health up and running....Make sure to provide a good amount of bright filtered light and warm temps...Good luck)
