    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.

    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.

    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.

    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.

    Here are a few links for you.

    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.
