Certified ExpertA.It may be stem blight which will burn itself out over time. Remove the affected branches.

June 13, 2020Q.We applied Neem oil to 39 berry bushes and 31 died. What happened?
Neem oil was also applied to apple trees, tomato plants, and rose bushes. The rose bushes died and the tomato plants don't look healthy. The apple trees are drooping over. Most of the blueberry bushes are 12 years old. We also had raspberry and blackberry bushes. The raspberry and blackberry bushes died first. The fruit on the blueberry bushes look hard and gray. We called the company and they said their product was safe. Our garden which was organic is gone and we don't know what happened.

Certified ExpertA.We couldn't speculate on what happened to your garden without more information, unless the plants were sprayed with Neem Oil during the hottest part of the day. That could burn the plants. The instructions specify to spray in the early morning or evening.
We do recommend Neem Oil for pests and even fungus issues; there are many manufacturers of this product and application directions should be followed on the containers. Some require diluting the products. Verify the label and its application directions.
Was your whole garden bothered by the same pest that it was used so widespread? A call to your local cooperative extension agent may help. You can discuss the issues more comprehensively.

T8W 0K7Q.Why Do You Say NOT To Use Aluminum Sulphate In Blueberries?
In your June 12/20 article by Heather Rhoades you say NOT to use Aluminum Sulphate. All of the greenhouses in my area carry only that and recommend it for blueberries. Can you give me more detail why you recommend not using it and only using AMMONIUM sulphate? Thank you.

June 16, 2020A.There are reports that aluminum sulfate can be toxic to blueberries if high rates are applied. Unfortunately, many gardeners try to quickly get their soil pH down to blueberry levels instead of making a gradual change and testing yearly. I am not the writer but that may have been the rationale. Here is a reference: https://www.canr.msu.edu/uploads/files/Lowering_Soil_pH_with_Sulfur.pdf

Colorado Springs 5bQ.Dog Attacked Blue Berry Bush Roots Gone.
Just bought the blueberry bush on sale from the grocery store. It looked healthy but wasn't bushy. My dog got it, ran around with it breaking the top off the root ball. I put the top in water & sniped off the small lower leaves, stems are about 14" tall. *Anything else I should do to save it?

Certified ExpertA.For this kind of blueberry, in your zone you should probably wait until early spring when all danger of frost has passed.
