Answer 1

Unfortunately, without being able to see some signs of the exact cause, I can't really give much recommendation on the treatment. There are quite a number of factors to consider. Things such as overwatering, underwatering, insects or other pests, nutrient deficiencies or excesses, and more.

Taking a guess, I'd say that it is bacterial or fungal, but this is nowhere near an answer. This is just a guess because of the time of year. From here, to get an accurate answer, I'd recommend testing all of the parameters that you can. Testing soil pH, nutrient levels, moisture levels, and inspecting for insects or pests will be the first step. If you'd rather have it done for you, then you can take samples to your nearest extension service.
