As a general rule, apple trees require regular feeding in order to ensure healthy growth and high-quality fruit production. When it comes to fertilization, it’s important to take into account the age of the tree, as well as its specific nutrient needs. Here’s what you need to know about recommended fertilizer doses for 5 years of apple tree growth.
First Year: Establishing Roots
In its first year of growth, an apple tree is still establishing its root system and does not require much fertilizer. A small amount of balanced fertilizer (such as a 10-10-10 formula) can be applied at planting time, but be sure to follow the manufacturer’s instructions for dosage. Alternatively, you can use a slow-release fertilizer to provide a steady stream of nutrients throughout the growing season.
Second and Third Years: Building Strength
During the second and third years of growth, apple trees are focused on building strong trunks and branches to support future fruit production. This is a critical stage in the tree’s development, and extra care should be taken to ensure the tree has the nutrients it needs to thrive.
For trees that are growing well and exhibiting healthy foliage and strong branches, a yearly application of balanced fertilizer is recommended. Use a formula with equal parts nitrogen, phosphorus, and potassium (such as a 15-15-15 or 20-20-20 formula) and apply in early spring before new growth begins.
Fourth and Fifth Years: Prepping for Fruit Production
In its fourth and fifth years of growth, an apple tree should be nearing maturity and getting ready to produce its first crop of fruit. At this stage, it’s important to provide the tree with enough nutrients to support healthy fruit development while also promoting overall growth.
One recommended fertilizer schedule for fourth and fifth-year apple trees includes applications of balanced fertilizer in early spring and again in early summer. Use a formula with slightly more nitrogen than the previous stage (such as a 20-10-10 or 30-10-10 formula) to encourage leaf and stem growth. Be sure to follow the manufacturer’s instructions for dosage and application frequency.
In addition to regular fertilization, apple trees also benefit from regular pruning, watering, and pest control measures. By taking a holistic approach to tree care, you can ensure healthy growth and a bountiful harvest for years to come.
