My Pops has 8 blueberry bushes he has carefully tended for some years. There are two bushes each, of four different varieties that mature at slightly different times. He has a fence and bird net for them. Unfortunately at his advanced age he isn't able to tend them like he needs to for an optimal harvest. Most years, he would have so many berries that mom would eventually start chewing him out. "Don't be bringing any more of those in the house! I'm not processing any more berries!"
Maybe this year I'll see about going up there and finding out everything he needs to have done for his bushes. I myself don't eat many berries, but those bushes along with his fruit trees, wild raspberries, mulberries, elderberries, and wild asparagus beds, are an important resource that should be kept prepared...
