How to Care for Semi-Dwarf Apple Trees
- 1). Prune your semi-dwarf apple tree immediately after planting to develop a strong framework. Trim the branches back so that the tree stands around 26 inches. Remove any additional dead or damaged branches, cutting those back to the trunk. Use sharp, sterile shears to make the flush cuts.
- 2). Apply a 3-inch layer of organic mulch around the canopy of the dwarf apple tree. Keep the mulch about a foot away from the trunk to prevent root rot and canker disease. Replenish the mulch periodically.
- 3). Create strong crotch angles when the branches reach about 6 inches in length. Apply clothespins on the branches of the apple tree, at the trunk. Angle the clothespin to create a nearly 90 degree angle. Allow the clothespins to remain in place throughout the first growing season.
- 4). Irrigate the apple tree bi-monthly. Water the tree slowly and deeply so that the water reaches 2 to 3 feet deep into the soil. Adjust your irrigation levels during periods of heavy rain or drought to prevent improper irrigation.
- 5). Take a soil sample from your apple tree's planting area. Dig a hole 6 feet deep and take your sample from that depth. Use a sterile shovel to dig the hole and place the soil in a clean container, so as not to contaminate the sample. Purchase and complete a soil test with your soil sample to obtain the area's pH levels.
- 6). Feed this semi-dwarf tree once annually in the early spring. Use the results of the soil test to determine the appropriate fertilizer combination. Select a slow-release fertilizer with a 3-1-2 ratio, as explained by the Texas A&M AgriLife Extension.
- 7). Prune the semi-dwarf apple tree each spring, just before the growing season begins. Remove dead and damaged branches. Trim back vigorously growing shoots and remove all sprouts that begin to appear around the base of the tree.
- 8). Take steps to prevent the potential of insect infestation and disease of your semi-dwarf apple tree. Keep the tree's area free of debris and defoliation. Control pest infestations by treating the apple with an insecticide that is designed for home orchards. Speak with your local specialist for selection assistance.
- 9). Harvest the semi-dwarf apple tree in the late fall as the apples begin to ripen. Take an apple from the tree and sample it to determine the tree's harvesting time. Remove the apple from the tree by gently pulling the fruit from the spur, leaving the stem attached. Harvest the tree daily until all the apples are removed.
