hyssop #862574

Asked March 26, 2024, 5:45 PM EDT

Last summer I noticed some unusual leaves on my hyssop plants. When I looked it up I found that a virus was likely responsible. This year all the new plants have abnormal leaves. I attribute this to spread of the virus. What is the best way to prevent further spread? I plan to discard all the plants showing the abnormal leaves. Thank you. We also have a small juniper with rust. How should it be disposed of?

Can you send us photos of your hyssop please?

The Juniper with rust doesn't necessarily need to be removed. Does it look unhealthy otherwise?

If you feel you need to remove it you can just send it to the dump. If it is small enough you could bag it.  This native tree is beneficial,  and the disease pathogen (which can carry for miles) isn't terribly destructive unless you are trying to grow edible fruit.
