I have an Aglaonema (also commonly known as a Chinese Evergreen) at my desk at work. Over the past month or so, its leaves have been yellowing and dying rapidly. This is how it looked today, a Monday; last Thursday, I removed the dead and dying leaves, so the yellowing you see in the photograph happened over four days.

My desk has a southwest facing window high up on the wall; the plant is on a level with the window and is a few feet from it. There are tall trees near the building, but they're not in leaf yet, so it gets some indirect sunlight every day. I've been sitting at this desk for 1½ years, and my plant wasn't like this last year.

What is causing this, and how can I help my plant recover?

Here is a brief symptoms guide which may aid you:

  • not enough water: older leaves die and are dry and papery
  • mealybug infestation: white cottony tufts in the axils of the leaves
  • natural aging: older leaves close to the base of the stem yellow and dry, rarely more than one or two at once
  • too much water: many leaves yellow, oldest ones first, leaves retain their turgor

This looks like overwatering to me. This is the most common cause of stress or death for houseplants.


  • reduce watering
  • move closer to light or increase lights
  • consider rejuvenation: cut one third of the stems off leaving six inches of bare stem and root in water. Once they are rooting cut another third of the stems off the parent plant and root in water. Aglos readily bud from old stems. With this method you can rejuvenate the old plant and have a backup in the form of cuttings you can pot up in six to eight weeks. Reduce watering for the parent plant after you have cut back the foliage to make cuttings.

Edit: Michelle suggests repotting which can be helpful. It depends on the extent of the overwatering. If the plant is potbound and a little bit overwatered, then yes, repot. Severe overwatering is quite a stress on a plant and repotting would just add more stress. In this case taking cuttings as suggested is a better idea.

Check the roots in the soil. New roots are firm and white. Old roots are brownish. Dead roots can be soft and mushy or papery if they have dried out.

    I wonder whether repotting wouldn't be warranted. We had a similar one doing poorly at work, and repotting helped. I think the roots had actually prevented the pot from draining properly.

  • I've reduced its watering and the leaves don't seem to be dying as quickly now. Also, I've got cuttings sitting in water, waiting for roots to form.

Do you ever fertilize it? Have you ever repotted it? They don’t need much in terms of nutrients (4-6 times a year, water with an average/normal houseplant fertilizer diluted to 1/4 strengh), but eventually they’ll languish if they’re never fertilized.


Take this answer with a bag of salt at least. In other words: I can't back it up.

Problem: the pot is too small. Inside is all a rootball and no soil or nutrients.

Solution 1: repot in a larger container with nutrient-rich soil.

Solution 2: apply liquid fertilizer several times per year.

Solution 3: cut back, as in: destroy half the plant. The small roots cannot support such a large leaf mass.

Solution 4: let it be, it won't die for at least an year.
