Yellowing And Mottled Leaves On Both Of My Brugmansia’s. They Are Both In Large Pots In A East-south Exposure. I Keep Them Well

Question

watered and I fertilized with slow release flowering plant food. I don’t see any mites, even with a magnifying glass. Both plants have flowers coming.

Answer 1

Unfortunately, your photo did not come through. I am unable to identify the problem.

There are a few reasons that this would happen, though.

Overwatering can cause many symptoms and promote disease. Make sure to let this one dry, thoroughly, down to about 2 or 3 inches before watering again.

If this is an infection brought about by watering habit, then a fungicide may be necessary.

Another possibility will be, actual, deficiencies or pH swings.

There is a possibility of it having contracted Mosaic Virus. This is not treatable and will mean that the plant will need to be discarded.
