My peace lilies are watered, but some of the stems of the leaves are turning black, what would be causing this? The plants are indoors with low light.

Hi Jaz49, Welcome!
I wonder if perhaps your Peace Lilies (Spathiphyllum) is getting a bit too much water?

Jaz49, might be too much water as Lin suggested. The plants do like being moist, but still got to give intervals in watering. They are indeed low light plants, so it is okay grown indoors. But intervals in watering needed. Does your container have drainage holes?

Hi Tarev, they were in self-watering pots originally, but I now have them in pots with good drainage, but I am pretty sure the damage was done before I re-potted them into the new pots. I also originally fertilized them with Searles 5 in 1 mix at 40mL per 4 litres which I now suspect was overkill.

Ah, it may be still suffering from fertilizer burn then. Don't know if it can recover from that without repotting into fresh media. I have been able to recover my Peace Lily from severe dryness, almost dead looking, with gentle watering. But with fertilizer burn, not sure.

I have one also. Mine was frost bitten though. Keep it in low light and don't water too much. However if it's fertilizer burn, it probably won't come back.
Give it some time and chip away at the dead withered leaves. Watch for new growth too. It'll need some time to recover but it can happen .

Peace lilies and watering, I have a moisture meter, when I put it in the soil of my peace lilies it always reads moist even though they have not been watered for 20 days. The meter reads correctly because I have tried it with a second one and got the same results. Are these suitable to use for peace lilies and is 20 days a long time between watering or can they go longer? The pots have good drainage and are not on a wet saucer.

Jaz49, it will also depend also on your prevailing temps and humidity levels in your growing area. The higher the humidity levels, the longer it takes for media to dry out. Or maybe your media is really that moisture retentive so your moisture testers reads as high.

Observing my peace lily, growing it in cool to warm moist conditions better than getting too crunchy dry. So got to be mindful of temperature and moisture levels.

thanks tarev, most things I read about watering peace lilies that do give a time frame, say water once a week, which make me wonder if 20 days between watering is extreme and abnormal for peace lilies. My humidity levels are not high, average temperature is around 25 degrees Celsius, the soil is premium grade indoor potting mix and they are mostly in shade, so I guess my main question is this: generally speaking, is 20 days between watering the plants abnormal?

Jaz49, not really abnormal. If media is really still moist maybe it is. Some potting soils have wetting agents to extend moisture levels.

Other ways to make it less soggy, adding some more perlite, or reducing container size, so dry out time is not that long. But it has drainage holes, so I won't be too worried. Other things happened to your plant which may have added distress to it.

So it could be a combination of factors happening to the plant, too soggy and the fertilizer burn.

But I typically do not want to give up on a plant if it is still trying to grow. Observe it a bit more. I read in some discussions in another site, someone suggested using distilled water to help flush out excess fertilizer salts. Don't know if that will work in your case. At this point, any remedy will be welcome, I think,

I've had the same spathiphyllum for almost 48 years. I put it outside in a shady spot in the summer where it gets regular water at least once a week, depending on weather. In the winter, it lives on my piano w/ no direct light. When it starts looking limp, I water it.
When counting, try not to mix chickens with blessings.
