I just would like to know if my plant is an oleander so I could take necessary precautions. thank you.
Need to find local Extension Office for Oleander questions
FInd your local extension at this website: Search.Extension.org
I somehow lost an entire “Hedge of Older Oleanders” – some 25 plants that just seemed to die and wither away. I tried to talk to our local nurseries to no avail – as they couldn’t tell me what might have happened and/or caused the oleanders to die and wither away…. That said, I’m in the process of replacing the lost oleanders and want to make sure I remove the older plants and plant the new plants in appropriate soil so as not to expose the new plants to anything in the soil that might have caused the problem. I have attached a few pictures of the plants – please notice the “black” in the center of the large stems – the “brownish colored leaves” and “sick state of affairs of the plants”….. If anybody might have an idea of what caused this problem – please advise me at texaslarry@outlook.com as I do not want this to happen in the future.
I found some research information on an issue in your region of Bacterial Leaf Scorch of Oleanders.
Here is the link.

I would talk with your County Extension Office and see if they have any other information and how to keep insure the health of your new plantings.
I have a healthy plant on the left side of my house, but then I have the same type of plant on the right side of my house and it is dropping leaves, which turn yellow, and it is not looking healthy. Why is that happening?
Hm, it would be hard to say without seeing it. Please include photos, and more information about the differences between the sides of the yard.
In the meantime, this article will give you information on their care: https://www.gardeningknowhow.com/ornamental/shrubs/oleander/oleander-growing-tips.htm
Hey, the leaves were going yellow and dropping off. I then put it outside because it's extremely hot in the conservatory. The flowers died off and the stems were slightly purple. We also had high winds which probably didn't help. I've now brought it back in and cut the dead flowers off but to me it doesn't look healthily. There is still purple/brown on the stems and some leaves. Can anyone help out? Cheers
It looks to be overly wet. Though they do need plenty of water, they also need to dry out down to about 3 inches or so between watering.
They are, also, VERY HEAVY feeders! They will need to be fertilized often. This article will give you a little more information on the care of these: https://www.gardeningknowhow.com/ornamental/shrubs/oleander/growing-oleander-in-containers.htm
Could you please send me some information about the care of these shrubs as they have plenty of flowers on them but not opening just dropping off what am I doing wrong many thanks
Make sure to water during dry periods.
A balanced fertilizer can be fed to them.
Inspect for pests and treat accordingly.

I have some mature oleanders that are infected with witches broom, will the disease jump to other plants?
Not necessarily. This is a broad term that describes any type of stress, disease, or otherwise genetic mutation, and will depend on the cause as to if it is contagious or not.
Most of the time, you can choose to cut the growth off if you wish. There is no further treatment required.
