Hello everyone, this is my first post here so I'll give you a quick bit of history.
We bought this property in Placerville, California about 8 years ago. On one of the hills is a small orchard with 2 Damson (I believe) plum trees, 2 wild plum trees a very tiny pear and two apple tree's. I'm very new to gardening and especially fruit tree care and it wasn't until recently that I decided to start looking after them as that hillside has grown a little wild.
Anyway, I just discovered I have a pretty serious scale infestation. All of my plums have it and at least one of the apples has it. I've been doing as much research as I can but I'm to the point where a little direction could help.
Based on my research I believe I have Kuno scale (Eulecanium kunoense)? I've read about the various treatments but the one thing I can't figure out is what to do if my tree's have fruit. None of the fruit is ripe yet so I'm worried if I spray my tree's if I'll hurt the fruit. Do I need to wait until winter to treat it?
Any help would be great, thanks!
