By their third year in the ground, your fruit trees will be well-established in their environment, and may even begin fruit production. Since their needs change as they reach fruiting maturity, you should fertilize your fruit trees (as needed) during the growing season.
Fertilizing trees that are three years and older with high-nitrogen fertilizer promotes vigorous green growth, which, in turn, supports larger fruit crops. Apply a high-nitrogen fertilizer, like our Stark® Orchard Fertilizer, once either early in the growing season (2 weeks prior to bud break) or sometime before July. Avoid fertilizing too late in the season as this forces tender growth later in the year, which is more susceptible to winter injury.
Always test your soil for nutrient excess or deficiencies before applying soil additives. Over-fertilization has adverse effects on plants, trees, and the environment.
