Spring orchard management plays a crucial role in the health and productivity of fruit trees, especially when it comes to fertilization and pest control. Based on years of experience, I would like to share some practical suggestions for effective spring care:
Applying organic fertilizer and soil conditioners is essential for maintaining healthy soil structure and microbial activity. It’s important to reduce the overuse of chemical compound fertilizers while ensuring adequate supply of micronutrients. From recent field visits, it has become clear that many orchards are facing serious issues such as bark peeling, tree death, and branch dieback. The main cause behind these problems is soil degradation, which negatively affects the root system's environment. As the soil becomes harder and more compact, green moss grows under the tree canopy, and even beneficial organisms like earthworms are disappearing. Without a favorable root environment, trees struggle to absorb water and nutrients, leading to poor growth, rough bark, and increased susceptibility to diseases.
In spring, it's also vital to pay attention to the supplementation of zinc, a key micronutrient. Last winter was particularly cold, and orchards that did not receive proper autumn fertilization were more vulnerable. This often resulted in weak shoots with no leaves and low maturity, creating a "bald" appearance. After harvest, timely autumn fertilization is necessary to replenish the tree’s nutrient reserves and prepare for the next growing season.
When choosing spring fertilizers, consider the high energy demands of flowering. For orchards that received autumn fertilization, high-nitrogen options like Lion Horse 21-8-11 or Entek 26 and 22-7-11 are suitable before bloom. Later, high-nitrogen and high-potassium blends such as Zhongde 21-8-20 or 16-12-20 can be used, combined with additional nitrogen sources for optimal results.
Pest and disease control in spring is critical. This is the best time to implement preventive measures effectively. Combining bark scraping with applying protective agents on wounds can help. Once scale insects fall off and before flowering, timely chemical treatments should be applied. The principle is to act steadily, accurately, and thoroughly. Although this year’s pest and disease pressure seems relatively low, farmers must remain vigilant. Neglecting spring prevention could lead to significant losses later on.
By focusing on soil health, proper nutrition, and proactive pest management, orchard owners can ensure stronger, healthier trees and better yields. These practices not only support long-term sustainability but also improve the overall resilience of the orchard.
