The Honeycrisp apple is the product of a 1962 apple breeding program at the University of Minnesota. A patented apple cultivar, the Honeycrisp is sweet and crunchy and a great choice for inclusion in juices and jellies. Grow the Honeycrisp as you do other apple varieties: Give it lots of sunshine and deep soil with good drainage. Honeycrisp apple trees don't do well in hot regions, as the fruit quality will suffer. Plant the Honeycrisp apple in the spring.
Deliver a soil sample to a county cooperative extension service. The analysis will help guide you in the appropriate soil amendments and adjusting the soil's pH.
Til the soil amendments, as recommended by the soil test, into the top 18 inches of soil in a 2-foot square area around the planting site.
Dig a 2-foot deep hole, twice the diameter of the Honeycrisp apple tree's rootball. Place the rootball into the hole. Place the graft union (knob on the lower end of the trunk where the Honeycrisp was grafted onto the rootstock) 2 inches above the soil. Add soil, if necessary, to raise the tree to the proper height.
Pour soil into the hole to cover the roots. Work the soil around the roots, using your fingers. Fill the hole gradually, packing the soil by hand as you go.
Water the Honeycrisp apple tree until the water puddles. Keep the soil moist, not soggy.
Prune the newly planted apple tree in the spring, just before the buds appear. Cut the main trunk so that it is 36 inches above the surface of the soil. When new growth from this pruning is 3 inches long, choose the strongest upright shoot and cut off the others. Remove any new shoots 3 inches below as well.
Fertilize the Honeycrisp apple tree according to the results obtained from a yearly soil analysis. This will ensure that you don't overfertilize the tree and that it receives any nutrients that may be lacking in the soil.
Remove weeds out to the tree's dripline. Weeds compete with the tree for water and nutrients and provide breeding beds for pests.
Clean the planting area periodically to control pests and to discourage disease. Rake all fallen leaves and fruit.
Apply a fungicide with insecticide labeled for use on apple trees in the spring, when new growth appears. Apply at the rate suggested on the product's label. Follow the application instructions and warnings.
