FAQs:

  • Question: What time of year do you fertilize blueberries?

Answer: Fertilizing in the early spring, before the leaves have grown in, is suggested. This allows the blueberry’s roots to absorb the fertilizer before starting its active growth stage in the summer. Feed young plants twice in the spring, once in the early spring and once in the late spring.

  • Question: Is Epsom salt suitable for blueberries?

Answer: Epsom salt provides brief comfort if your blueberries require magnesium. Sprinkle 1/4 cup Epsom salt around the plant in a 10-inch circle and water well in poor soils. A foliar spray delivers magnesium to the leaves that use it most.

  • Question: How can I make my blueberries grow better?

Answer: To retain moisture, suppress weeds, and contribute organic matter, blueberries benefit from 2-4 inches of mulch applied over the roots. Bark O Mulch, acid compost, sawdust, and grass clippings are all excellent choices. Every other year, repeat the process. Do not use cedar or redwood tree bark or sawdust.

  • Question: What can you not plant near blueberries?

Answer: Plants that are heavy feeders and demand more nutrients from heavy applications of compost or even organic fertilizers are not suitable companion plants for blueberries since they may injure your bushes if you pander to their needs.
