HELP!! I have a dieffenbachia that has been in my house for the past year and a half. Up until the past few weeks this plant has been healthy and growing. It is now aprox. 3 1/2 inches tall. A few weeks ago I noticed that the bottom leaves have yellowed and I removed them. Now the new growth has also shown signs of yellowing and has some brown. This is just shoot and I did my best to remove it. The plant has not been moved nor has it's care changed. What could this be. I have put the plant in a shower, washed it with soap and also tried to use a diluted alcohol solution all of which I have used in the past with success. What else should I look for or try. I do not want to give up on this plant as it has done well for the past year and a half....and still has 5 very healthy looking leaves. Thanks for any advice you can give

How much water are you giving it? I let mine dry a bit between waterings. How much fertilzer? How much light does it get?

Just because you haven't changed anything doesn't guarantee that your plant will be trouble free. Plants that are over or under watered by just a small amount will do fine for a while until finally the roots are damaged to the point where it starts to affect the leaves. The same can happen if the light is a bit too dim.

You didn't provide much information, but I would hazard a guess that roots are starting to rot.

If you can e-mail a photo to me, I might be able to be more definitive.
