Hi there
I have black spot on a young apple tree, Wealthy, likely due to the humid weather conditions. Anyone know the recipe for Neem oil spray and application instructions. Also where to get Neem oil?

Yes and no, @Killerbunny . Neem oil is no longer allowed to be sold in Ontario (go figure) - it's not a manufactured chemical; it comes from the neem tree), but you can get it in spray form at many garden centres in the US, such as Lowe's ... I think I remember seeing it there the last time I was in Ogdensburg on a Tractor Supply run. Not sure if it's still available in Quebec.
