My Beautiful Orange Lantana Is Dying

Question

Hi! I have 2 beautiful and matured lantana bushes in the back yard. An orange circular lantana on one side of my garden, and a purple confetti one against a wall. Sadly, I noticed my orange lantana started dying after my landscaper trimmed it from the top on one of regular visits. I am not sure it that is the reason, or if pests are the reason for my orange lantana dying. Today, I also noticed some white spots on my purple confetti. Does the same fate awaits my confetti lantana as well? I love these plants. I would like some advice on how save my lantana please!! I have attached some photos for your review. Thank you in advance for helping me save my lantana plants!!

Answer 1

Yes, it looks like the shrub has contracted an infection. This can happen when pruned during a cold spell, or during the Fall wet season.

Normally, these will be pruned in late Winter or Spring, but can be pruned before the Summer heat as well.

For now, I would recommend treating with a fungicide. This article will help: https://www.gardeningknowhow.com/garden-how-to/info/using-fungicides-in-garden.htm
