The leaves on my Dieffenbachia are turning brown and also the new leaves. They look like the plant is very dry. I have checked the soil with moister tester and is a #2, is not in direct sunlight. What am I doing wrong? Thank you for your help.
Filtered sunlight is a good location for Dieffenbachia.
Also you may not be watering enough. Check the soil by inserting your finger an inch or so into the soil. If is is dry, you need to water. The soil should be consistently moist, but not soggy.

I believe I have a dumb cane plant, but maybe not. The leaves are reddish brown underneath. Once I can identify the plant, I can figure out how to best take care of it. Thanks.
Can you upload an image for us to make a identification for you?
My Dieffenbachia leaves keep turning yellow then fall. The plant grows very slowly. It loses leaves more than growing new ones! I need help to save my dieffenbachia. Thanks in advance.
Yellowing leaves generally indicate a watering issue; too much or too little.
The soil should be moist but never soggy.
Check the soil and water only when the top inch or so have dried.
A bright filtered light location is best and a regular fertilizer schedule will help keep a healthy growing Dieffenbachia.
Here is an article that will help refresh you on the care requirements.
My dieffenbachia sprouted several new baby leaves at once, at the same time the large mature leaves started dying. The new leaves never open or mature. Instead, they turn brown and remain curled in. Some continue to grow in size without every opening. Other plants in my office are thriving and had one with a bad infestation return from the dead but I can't seem to help the dieffenbachia.
My top theory is that this is an insect infestation. More information on the insects that afflict diffenbachia can be found here:
Have you been fertilizing your plant? When leaves turn brown and curl like this, it could indicate too much fertilizer. And, how often do you water your plant? Is it possible you have been over-watering your plant?
Lastly, I would recommend a review of the care of diffenbachia at the following link:
It's healthy at 5'3; however, the stem has not thickened and I'm concerned that it will break at some point. I have pole support for 2 sides. Unlike other plants that I have, pinching the new growth to cause the stem to thicken hasn't worked. What can I do? thank you macklin
How to root the pruned off top?
Sometimes thin dieffenbachia stems are due to incorrect care or placement. I would double check the care of your plant using the information in the following article:
When a dieffenbachia grows tall and thin like this, the recommendation is to prune it. Pruning will invigorate new growth on the stem just below where you make the pruning cut. You can even take the pruned off top and use it to propagate more dieffenbachia plants!
Someone just cut it off and I rescued the plant, but I know little about it.
Here is a link that will help you with propagation.
My Dieffenbachia has white spots on the underside of leaves, which then yellow and drop. I have tried insecticidal soap and soapy water, with no success.
Spider Mites are a common pest on a Dieffenbachia, though this could also be Mealybug.
Neem Oil is a good treatment.
