How to Grow Blueberry Bushes in Michigan

Prepare a planting area for the blueberry bushes by testing the soil pH to verify it is 4.8 to 5.2. Work ground rock sulfur into the soil to a depth of 6 to 8 inches with a rotor-tiller and let the soil rest for two weeks. Follow package instructions for application rates based on the current pH and soil type.

Dig a planting hole that is slightly wider and the same depth as the blueberry root ball. Mix organic compost into the removed soil to increase the nutrient content and water draining properties of the soil around the roots. Set the blueberry bush into the hole and pack amended soil around the root ball to limit air pockets.

Water the blueberry bush generously immediately after planting. Provide 1 to 2 inches of supplemental water each week during the spring and summer months when the rainfall is not adequate. Do not over water the soil or create standing water as this promotes root rot in the shallow root system.

Fertilize the bush each spring with a 5-10-10 fertilizer after planting the blueberry. Test the soil pH in late spring to verify it is below 5.2. Apply ammonium sulfate fertilizer according to package instructions to lower the pH if it is above 5.2.

Apply a 3-inch layer of sawdust or bark mulch around the blueberry bushes. Refresh the mulch layer each spring to maintain a 3-inch layer. This will reduce weed growth and assist with soil moisture retention during the dry summer months.

Hang bird netting over the bushes once the first set of flower blossoms appear to prevent blossom and berry loss to birds. Construct a small spaced wire fence to prevent rabbits and rodents from damaging the plants or burrowing underneath them.
