So, I have been trying to find a blueberry companion list for quite a while by searching and I wasn't finding much of anything. So, I decided to do some of my own research and I looked up a list of blueberry pests and found out what predators ate those pests. Then, I found out what plants attracted those predators. Lastly, I searched each plant to see which ones could tolerate a PH as low as at least a 5.5 and this is my conclusion.
I haven't tested them yet but I thought I would share my companion plant list.
P.s. I wasn't sure if I should comment it on an old post or post a new one.... I was afraid it might be buried in the other post since that one is 8 yrs old so I decided to just create a new post so that it's easy to find.
