Copper Spraying - Avoiding Blossom
A t'villan made a remark that I was not aware of - which was avoid getting copper on blossom when spraying as it may affect it.
For those that spray, when you have leaves intermixed with flowers.....just short of individual hand painting each leaf, how do you spray.
I've got 4 plants that are showing black spots. I think it's septoria but too early too tell. Leaves are healthy but when you catch them in the right light, you can see some that are developing black spots.
