I need some advice about what to do with my blueberry patch. We recently purchased this Maine home late last fall, and having established blueberries was one of the selling points for me. During closing I was told these plants are several years old. Perhaps upwards of 5 years if memory serves. I am new to gardening and have been doing my research and I don’t believe these blueberries have been given/placed/cared for correctly. However I am not sure how to correct or what specifically should be corrected for them. ( I wouldn’t want to cause more harm than good) Currently there are 2 rows of plants spaced approx. 2 feet between plants and 3 feet between the rows. For a total of 10. I have included a photo for reference. Any advice is greatly appreciated! Thanks in advance!
