Thanks Steve, that is very helpful.
How many dahlia plants do you grow per year?
I really didn’t know about disbudding. All the guides I read never mentioned what you just
shared.
Not sure that I will have a whole lot of time to disbud.
Checked the plants tonight and there seems to be less leafhopper activity than the other day.
In fact, they were harder to find.
Mildew seems, not surprisingly, cultivar specific. Overall for the planting it may be on 10% of the crop, with Yin Yang being the majority of the ones showing symptoms.
So I guess the tunnel is not as a big help as I thought for powdery mildew, as I read it does not need water to spread like other foliar diseases.
Perhaps I should have begun doing weekly Cooper sprays (if that is safe and effective) a couple weeks ago. I have a bag of the really good stuff that is copper soap. It’s reddish if I recall. Can’t remember the brand but I think it’s made in Europe.
Lastly, talked to a florist today with 4 locations that also does a little wholesaling.
Supposed to hear back from her about buying dahlias. She had to dig up some numbers of what she bought and paid last year. She’s been kind to share that with me.
