Q.Lesion on petunias petals
Hi,
I’m from Indonesia. I have problem with my petunia, I notice there a few spot on the petals, it grew larger day by day. It infected all the blooms. Is it infected with botrytis? Are there any anything I can do? I also attach the photo. Thanks so much.

This is common when water droplets get on the flowers. It is best to water them in a way that does not wet the flowers, in order to preserve them for as long as possible.
