Companion plants around blueberries
I planted 3 blueberries. Until the plants grow they take up a lot of garden space. I was wondering about planting a companion to take advantage of the empty space and maybe to keep unwanted "predators/disease vectors" away. Someone said that blueberries had shallow but extensive root systems and didn't do well with competition from other plants close by. What do you recommend? Shall my bluebs remain lonely until mature?
