07111Q.What could be reason for cereus blossom drop?
Hello, After not having any blooms for more than fifteen years, I discovered a blossom a few weeks ago. In the past the plant wintered in my dining room but was kept in my cool basement this past winter. The blossom was not actively growing, looked pale, then dropped yesterday. My zone is 07111, we had a lot of rain this month and I'm wondering if the excessive rainwater could have been the cause. Attaching current pics as well as the blooms from the past. Thanks

Certified ExpertA.Excessive water, along with cooler temperatures will have caused this. They will prefer temps into the 90's and above. They are very sensitive to overwatering as well.

10001Q.Yellow bumps on night blooming cereus leaf
I have been rooting a night blooming cereus for about three months now. It is finally showing new growth. However, there are hard yelliwish bumps on the underside of the largest leaf. Some appear to have tracks going to them. I’ve looked at it under magnification and cannot see any insects. So I would appreciate being told what these are, if they are a danger, and if so, how do I get rid of them?

August 26, 2018A.I think this may be leaf damage from scale pests.
Treat the plant with Neem Oil or insecticidal soap.

Sylacauga AL 35151Q.My night blooming cereus has a powdery white substance on it. Is it from over watering ?
This plant was a gift 3 years ago. It has really taking off as far as growing and has had 2 beautiful blooms. I just don’t know how to properly take care of it....pruning, feeding, etc and of course, the white powdery substance. A lot of it rubs right off, but not all of it

Certified ExpertA.There are many things that will kill powdery mildew. This one will be easy to get rid of. The easiest way will be peroxide. Mix it at 1/4 strength into water, and spray this onto the plant and into the epiphyte soil that it should have come in. This will kill off the mold, and spores.

Certified ExpertA.These are aerial roots! They don't need to be removed, or even concerned with, unless you are going to take a cutting, and root a second plant. Then, these will take off into the new root structure.

Bronx, NYQ.Older night blooming cereus leaves have brown spots
New growth is shiny and green; older growth has small brown spots on leaves and along "spine" and in places long the edges of the leaves. Plant is currently in a west window and has not been re-potted in some time. I am in NY so the plant lives indoors. Since it is fall, should I avoid repotting and fertilizing, or should I give that a try? (am not able to upload photo, not sure why)

Certified ExpertA.You should definitely repot that into a cactus or epiphyte soil. It looks like it has a mild infection, which will likely be due to the potting soil, and being too wet for too long.
Make sure when you water in the new potting mix that you replace 1/4 of the water with peroxide. This will help kill off any remaining infection on the roots.

October 10, 2018A.When you say peroxide, is it peroxide I buy at the drugstore? Or is it the stronger peroxide that is carried by hydroponic supply stores?

Certified ExpertA.This is a fungal infection. This is usually caused by the soil remaining too wet for too long. It can be treated easily, but it will be best to maintain the plant properly to avoid future infection.
The next time that you water it, just replace 1/4 of that with peroxide. Water this in once, and it will kill off the infection. You may notice a little damage from the treatment, but it will be followed by aggressive growth.

December 20, 2018Q.disease and pest conditions of a night blooming cereus
I have a Dutchman's pipe cereus. It has always been healthy but has been moved to Miami and has developed a condition where stalks that have been flattened into leaves become skeletenized in part of their growth area. New leaves continue to sprout around this but often develop the condition also. Is this sunburn? Is there anything I should do? Linnea Berg Thank you.
