Why is powdery mildew becoming such a problem right now?
14:21
So this time of year, people are seeing loads of powdery mildew because it has been repeatedly infecting plants since early springtime.
14:29
It's gonna be much more dormant during the winter, where you won't necessarily get lots of new infections, but if the weather is mild enough and sheltered enough, you still could have powdery mildew on anything that has got herbaceous, soft leaves left.
14:40
The real problem this year is that it's been so dry, and droughted plants with dry roots are really vulnerable to powdery mildew attack.
14:49
The plants have stayed droughted, but we've had enough humidity for the spores to germinate on those leaves and spread across them with their thick mats of mycelia and block out that leaf tissue.
14:59
High humidity, hot weather, dry roots for the plant is the perfect storm for powdery mildew to take hold, and for that humidity, you also need lower air movement.
15:09
So we haven't had a lot of windy days either.

So is powdery mildew something we're just gonna have to live with these days thanks to, you know, the heat waves we're experiencing and with climate change making that more likely?
