Coppertina Ninebark is disease free so far this year

Last July I wrote about “buyer beware” when deciding to plant Ninebarks in the landscape. I originally planted three Coppertina Ninebarks in May 2015. Two of them succumbed to powdery mildew and witch’s broom. Last fall I had some leftover mix of a disease control that I had used for a couple other plants. I took what was left in the Ortho sprayer and dumped it around the base of the remaining Ninebark shrub. (yes, I know that’s not according to package label directions!)

When the leaves came out this Spring, I watched for recurrence of the mildew. Surprisingly I didn’t see any. So far – June – there is still no mildew and the shrub is thriving with lots of new growth and the color that the nursery websites show it to have.

I’m still leery of this shrub but if the mildew stays away, it may prove to be a very nice shrub. It is about a foot taller than last year and about 2-feet wider.

I’m tickled!
