Will witches broom that is on my oleanders affect other plants?

Question

I have some mature oleanders that are infected with witches broom, will the disease jump to other plants?

Answer 1

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.
