oleander tree suckers have richer greener leaves than the ones already on the tree

Question

My oleander trees are suffering from the incurable disease affecting most oleanders in San Diego…….The leaves are mottled green and brown and look sickly, however the suckers which are growing from the base are brilliant green and look healthy.Can I let these suckers grow to replace the sick leaves, or will they too be eventually affected with the disease?…Thank you. ron larocca [e-mail]

Answer 1

Yes, you can cut them to take over, but they will eventually succumb to the same disease. Once plant diseases have established in areas heavily populated with humans they are very difficult to rid.

Your extension service is probably well aware of the issue. They will give you means by which to control the illness, but if this is widespread, as it sounds, then you won’t get rid of it.
