How to Grow Apple Trees in Michigan

Choose a sunny location that contains well-drained soil with a pH between 6.5 and 7.0 in which to grow your apples. Soil alkalinity and acidity varies throughout Michigan, so test the soil with a soil testing kit if you do not know its pH.

Amend the soil with lime if the pH is below 6.5 or with peat moss for a soil with a pH above 7.0. Add either amendment according to label instructions, after breaking up large chunks of earth with a pitchfork.

Plant your Michigan apple trees in holes that measure twice the width of their root balls. Dig the holes to the same depth as the current nursery containers. Space the holes at least 35 feet apart to give the apple trees plenty of room for expansion.

Remove the apple trees from their nursery containers. Set one apple tree in the center of each hole. Make sure the graft union (transition point where the roots meet the trunk) is above the soil line. Backfill the holes and gently tamp the soil with your foot to remove air pockets.

Water the apple trees generously using a soaker hose. Apple trees require at least 1 inch of water per week to thrive. The yearly average rainfall in Michigan is between 33 and 36 inches, considerably less than the 50 percent necessary. Therefore, Michigan apple trees require supplemental watering, especially during dry periods.

Apply a 3- to 4-inch layer of mulch around the trees to protect the roots from the chilly, Michigan winters. A layer of straw or bark chips will also improve water retention and reduce weed growth.

Prune apple trees during the winter when the trees go dormant. Remove dead or damaged branches with a pruning saw or sharp pair of pruning shears. Dormancy is also a good time to remove any branches that grow inward toward the center of the tree.

Apply a nitrogen fertilizer to the soil around the apple trees once a year. Check the packaging label for allocation amounts and time frames.
