these are mature blueberry plants that are a number of years old that i've transplanted 2 months ago. they seemed to be doing well but i find that one of them has about a quarter of the plant that just seems to be rotting. the plant beside additionally seems to be showing a similar sign. do i need to prune this away immediately? i have been watering every second day to get them established... might i be watering too much? there are five other plants and so far they look pretty good. any advice much appreciated! i think this might be a disease that i need to cut out. https://pnwhandbooks.org/plantdisease/host-disease/blueberry-vaccinium-corymbosum-bacterial-canker
