Birch hybrid campanula

Zone Salem Oregon Zone 8 | Brooke100 added on June 12, 2018 | Answered

I had fir bark dust blown in around all my shrubs and my campanulas. 1 month later my campanulas bloomed and were looking wonderful and now big sections of each plant are dying. Just looking crisp like they needed water which they didn’t. I can’t figure out what is happening

As campanula expands, it sends down roots from long stems. I wonder if the force of the blown bark, dislodged or damaged those fragile roots. At any rate, the plant is now stressed. I suggest gently lifting the edges and pulling the bark away from underneath the plant. Check carefully, including leaf undersides, for the common foliage pests: aphids, whitefly, spider mites, and thrips. These tiny pests suck juices out of the leaves and can be present in great numbers. Trim out unhealthy foliage and fertilize with a liquid fertilizer to give your plant a quick boost. If you find pests, a blast from the hose, Safer insecticidal soap and neem oil are treatment options. Research the particular pest for most effective treatment approach. An extreme but comprehensive measure in diagnosing problems is to lift the plant and examine it carefully for pests, root rot and crown rot. If soft roots or crown are discovered, divide the plant and cut out the rot.
