If you are planning to grow blueberry bushes or you have them in your garden, then applying fertilizer will help give you sweet and quality fruits during harvest. The blueberry plant performs well in acidic soil. Thus, fortifying the soil with the right nutrients will help keep the blueberry in tip-top shape.
Since the blueberry plant has roots that grow about 12-inches, it becomes difficult to absorb nutrients and water as plants with deep roots. Also, they have challenges growing through compacted soil. So, adding fertilizer helps them retain water.
