Office plants, need tips?

Hi,

About three months ago I was hired at my current office. We have three plants around the office that I took over on their care.

Peace Lily
Was being overwatered and never misted. Most of the leaf tips have turned brown. Currently I've been watered once a week, when it starts to droop. I'm getting better at recognizing it before it is extremely obvious. I have pruned off the worst off leaves, ones that more than just the tip was browing or if they were on the floor and wouldn't raise. I mist it everytime I water. It has started thriving, growing at least 7 new leaves, two which have unraviled and five are currently still twined.

Pothos(I think)
Wasn't being watered hardly at all. Most leaves were brown, but since has really thrived. Very lush and is almost about to drape off the cabinet it is on. I water when the top soil is dry.

Cat Palm
Now this guy was in horrible shape and still kinda is. I struggled to figure out if it was a cat or an acena(?), but later found it to be a cat palm. ALL leaves were brown at the tip and the whole plant is tilted to a side. One morning I came in to find two of the fronds to have fallen on the floor. I pruned off many stems, making it a little healthier looking. Unfortunately it is the first thing anyone sees that comes into our office so I also trimmed the tips just to make it a little easier on the eyes. Water when top soil is dry.

Now. I want to know, am I watering all of these plants correctly. What more can I do to help them thrive, especially the cat palm. I will upload pictures as soon as my phone sends it to my email.

The cat palm prior to the little bit of trimming I did. I believe it may need to be repotted?

These plants look a lot better than your description.

Yes, I would repot the palm if/when practical at an office. When there are so many roots and so little dirt (judging from the appearance at the surface,) drying happens so quickly, and there's hardly any soil to soak up and hold any excess water. This constant flux between too dry and too wet is stressful. Is it leaning toward the light? If so, you could turn it around halfway so it will lean back the other way.

Since these pots are unable to allow excess water to escape, err on the side of caution when adding water. Using a watering can with a tiny spout opening helps you apply less water but more evenly over the surface of the soil. If left standing in the outer pot(s,) excess water not absorbed quickly can cause roots to rot. Looking for signs of pre-wilt on the peace lily is a good plan, you'll get very good at recognizing that. Actual wilt is quite stressful on the plant, so, as you're doing, continue to try to avoid letting it get like that. You've discovered well that Pothos would prefer to be a little too dry than a little too wet. Too dry = oldest leaf is sacrificed. Too wet = risk of rotting roots.

Also because excess water can't escape, excess chemicals usually found in tap water can't escape either. If the petty cash fund will allow, using distilled (not bottled drinking water, cheap gallon jugs of distilled,) will ensure the water doesn't have any chlorination, fluoride, lime, etc... which can build up to toxic levels over time in a pot without a drain hole. Not all tap water is as dangerous to plants, but I think it's a lot easier to use other water than try to find out what's in the tap water. It can be different in different cities, and even from day to day from the same tap.

The sticky at the top of this forum should be helpful to read.

I've been taking care of them for about three months now, I didn't get pictures of the Peace Lily or Pothos prior to yesterday. The cat palm is my main concern as it looks hideous currently. The roots are showing, from lack of dirt and too many clusters all together.
