Q. Dieffenbachia Lily

I have had a Dieffenbachia Lily for about 18 months with no problems. Lately, the leaves have started to yellow. It does not require watering and it has been put in good light. Please advise.

While they do not require much water, they do need some water to survive. Water the plant when the soil is dry.

 

If you have been providing water, it may be a fertilizer issue (though they need little fertilizer) or it may be rootbound. Check the roots and give it some 1/4 strength water based fertilizer.

Q. Dieffenbachia

Do Dieffenbachia bloom? I have one (of many, I have been growing them for 35 years) and it looks like it is about to bloom. There are no outward signs of insects but one large ‘something’ like a leaf attempting to open that is swollen and NOT opened now for two weeks. There is one other small leaf that is partly open but one side has not fully uncurled. Have you ever encountered this?

The dieffenbachia may bloom with a flower that looks much like a calla lily. The problem is that the plant will usually die once it is finished blooming. However, by the time a dieffenbachia is ready to bloom, it will almost always have new side shoots growing from it, which you can take to grow a new plant. Keep in mind that flowering is also a rare event when grown as houseplants, so if you get one to bloom, consider yourself lucky!

Q. Infestation of White Tiny Attachments to Top Side of Dieffenbachia

My Dieffenbachia suddenly is covered with very tiny white things that are attached to the top side of the leaf. They stick straight out from the plant. They do not move. Also, perfectly healthy leaves are dropping right off. Never had this problem before. PLEASE help.

It sounds like mealy bugs, though it could be some other type of pest. Nonetheless, it can be treated with neem oil. Here is more information: https://www.gardeningknowhow.com/plant-problems/pests/mealybugs-white-residue-on-plants-leaves.htm

Q. How Do I Propagate a 6 Ft Dieffenbachia?

I have a 6 ft dieffenbachia that I would like to propagate. . . my dilema is how! About the bottom 3-3 1/2 ft of the plant has no leaves, the circumference of it starts at the bottom of about an inch and a half up to 2 1/2. The leaves have been turning yellow one by one. There is also a 2-ft baby attached to it in the pot (under the dirt). I don’t want to kill the big one. I would like to send a picture of it so you can see it. Can anyone help me? Please, any suggestions would be most grateful.
Thank you
Cindy

Q. Splitting a Dieffenbachia

Can you just cut the top of a large dieffenbachia and stick the stem it in the soil without rooting it in water first?

It is not as successful as rooting in water, but yes you can do this and have a pretty high chance of the cutting rooting successfully.

Q. Problem With Houseplant

I have a small Dieffenbachia that I bought recently and when it grows new leaves, they are yellow and misshapened. Also, a different houseplant has yellow spore-like dots on the back of the leaves. Could you let me know what the problem might be and how I can save my plants?

Q. diefenbachia cutting and propagating

I have just 2 days ago, taken a cutting of an older diefenbachia plant and re-rooted it into another pot with rooting hormone (stem root) and today, 2 days later, am noticing a yellowing of the leaves whence previously they were very green. Can you explain what is happening here or is it just because it will do so for a couple of weeks, as I remember previously this having happened.

The lower leaves of cuttings commonly yellow and drop off. This is because when the branch is separated from the rest of the plant, it no longer has water flowing into it through the plant's vascular system. The plant's response to no water is to pull nutrients out of the leaf - you see this as yellowing; pull water out of the leaf - wilting; then let the leaf go - dropping. That's why when you make cuttings, you generally pull off all but 2 or 3 leaves. Deiffenbachia is a little different, in that it roots so easily, people commonly just cut the stem into pieces and stick them into the soil. You should soon be the parent of bouncing baby dieff.
