I haven't been to a large number of fields yet, but from what I have seen and the reports I have been getting from growers we are seeing very significant damage due to frost across the province. Here is a picture from the Musquodoboit area yesterday.
There will be variability in the level of damage depending on the temperatures, duration of the cold, location and orientation of the field and the stage of bloom. However, we saw temperatures well below minus 2 degrees for several hours throughout the province. It has been many years since we have seen this kind of frost across the province this late into June.
The wild blueberry is an incredibly durable plant and there will be some fields that will still yield well despite the damage we are seeing now. There is no doubt, many fields in NS have taken a yield hit over the last 36 hrs.
