Honey Crisp apple trees produce a mottled red and yellow fruit. Each fruit offers a sweet, juicy and crisp taste. In its sensory evaluations, the University of Minnesota ranks the Honey Crisp as one of the best. The apples also offer the superb ability to be stored for long periods. A refrigerated Honey Crisp apple can easily last six months in perfect condition. Apple harvest usually takes place from mid-September to mid-October. The trees are hardy and relatively easy to grow. Plant apple trees in the spring for best results.
Select a site that offers full sunlight and ample room to accommodate the Honey Crisp's 30-foot tall, 15-foot wide spread when fully grown. Plant the tree with a pollinator companion, such as a Gala, Granny Smith, Empire, McIntosh and Red Delicious. Plant the cultivar within a 1/4-mile radius of the Honey Crisp apple tree for pollination to take place.
Dig a hole that is twice as large as the root system of the Honey Crisp tree that will be planted. Add peat moss to the soil at a ratio of 50 percent peat moss mixed with 50 percent garden soil. Place the tree into the hole. Tamp down the soil to remove air pockets between the roots and the soil. Water the tree thoroughly. Apply 4 inches of mulch such as peat moss, bark chips, saw dust or recycled plastic around the base of the tree to protect the roots and aid in water retention during the hot summer.
Wait one month and then apply 1-1/4 cup of 10-10-10 fertilizer 6 inches from the tree trunk. Water the fertilizer into the soil thoroughly. Fertilize the apple tree every spring for maximum growth and health.
Prune the Honey Crisp apple tree in the spring to allow sunlight to reach every branch. Prune out any branches thart are bunched, cross over each other or obscure sunlight from reaching the middle portion of the tree.
Apply a fungicide such as topsin, captan or strobilurins every year to the Apple Crisp tree after the flower petals fall. Follow the directions on the label for application instructions.
Apply CaCl2, which is common salt used on apple trees, to reduce a condition in the apple called bitter pit. Apply the CaC12 six times during the growing season at a ratio of 3 lbs. per acre. Spray on the tree thoroughly and allow to drip.
