I was told there was good results for mildew using a baking powder solution. If you know the formula, I would appreciate it. It also had small amount of dish soap.
Recipe: 3 tablespoons baking soda plus 1 tablespoon of Murphy's oil soap, dish soap, or a lightweight horticultural oil in 1 gallon of warm water. Mix well and let cool. Shake well just prior to spraying. Apply this spray (making sure to get the undersides of leaves) every 7 to 10 days until the powdery mildew is gone.

My shrub grows very well but it never get flowers on it. We bought our house a few years ago and they were already here. The shrub gets about 5 foot tall and wild looking. They are in the front by the walkway, so I need to trim them so they don't get in the way. Do I need to move them to a different location, although I think they like where they are? Just would love the flowers to grow. There are 3 plants about 5 ft. apart. Thank you.
Pruning for shape and thinning inner branches will likely be all that is necessary to keep growing ninebark shrubs healthy and attractive. If you prefer, renewal pruning to a foot above the ground can be included in ninebark shrub care during dormancy every few years. If flowering is the issue, it could simply be a lack of phosphorus in the soil (a soil test will let you know for certain). Adding bone meal to the soil around your shrubs may help with this.
We planted Ninebarks this June, religiously watered and they look fine. Was curious if I need to cover this winter because I am sure they are not fully established.
Ninebark plants are hardy to zone 3, and easy to grow. I wouldn't think they need special care for winter. Besides, if you cover them, you will miss the exfoliating bark, just one of the benefits of this shrub.
My ninebark has a white film on its leaves. How can I get rid of it?
It sounds like powdery mildew. This article has some information: https://www.gardeningknowhow.com/plant-problems/disease/get-the-cure-for-powdery-mildew.htm
I have a nine bark shrub. There are several new spouts coming from around the base of the shrub. Will these be the same as the original shrub? They are straight and 6"-3' tall. I have a nine bark tree also and it does the same thing.
If your growing the Nine Barks as a windbreak, as many people do, you can leave the sucker shoots.
I personally would remove them to keep the shrubs looking neater.

I live in Fargo zone 3, and wondering if Ninebark summerwine has a dwarf size. I want something that will not get so large! Full sun all day and looking for colorful small shrub like Ninebark in summer. Would like to plant but am concerned about its size.
I would recommend the ninebark shrub that is dubbed ‘Little Devil’ - it reaches 3-4’ in height and width, with deep burgundy foliage accented by pink blooms.
