Early Spring Orchard Management Techniques

Fruit trees are perennial crops that follow an annual growth cycle. As temperatures gradually rise, they enter a new phase of development. Early spring management plays a crucial role in preparing for the upcoming growing season. This period is vital for laying a solid foundation for the healthy growth of fruit trees this year. It's essential that orchard producers pay close attention to these key practices. First, it's important to spray an effective pesticide at the right time. During the bud swelling and scale loosening stage, overwintering pests and diseases become active. A single application of a strong eradicator during this period is one of the most critical treatments for fruit trees, which are long-term economic crops. You can use 30% diesel oil sulfur microemulsion diluted at 800 times or homemade lime sulfur with a Brix degree of 3-5. When spraying, be thorough—make sure every part of the tree and the soil around the base is covered. Second, apply a pre-sprouting fertilizer early in spring. Before the buds begin to open, the roots start to become active. Applying the right amount of fertilizer at this stage ensures even sprouting and strong new growth. Typically, 10–15 kg of urea or compound fertilizer per acre is sufficient. This can reduce the need for heavy basal fertilization later in the season. Third, perform shallow soil turning. In addition to improving soil structure and moisture retention, this practice helps destroy the habitats of pests and disease-causing organisms. Many underground pests like earthworms, beetles, and larvae survive in the soil during winter. Similarly, pests such as aphids and peach borers often lay eggs in cracks, weeds, or under fallen leaves. By plowing the soil early, you can expose these pests to freezing temperatures or predators, significantly reducing their numbers. Be sure to bury all surface debris, including dead leaves and weeds, to prevent the spread of pathogens. Fourth, manage flower buds and consider grafting if necessary. Based on the growth conditions from last autumn, some pear orchards, especially Cuiguan pears, may have experienced premature flowering, leading to insufficient flower buds. This can affect this year’s yield. Orchards that didn’t properly develop flower buds should be addressed before the sprouting season begins. For those needing variety improvement, grafting should be done in time. The best time for grafting deciduous fruit trees is before bud break (late February), while for evergreen species, it's best before new shoots appear (late March to early April). Finally, perform pruning and thinning of flower buds. Once the buds start to sprout, a careful pruning session is needed. Remove excess flower buds, non-productive buds, and overly dense or overlapping branches. For evergreen fruit trees, proper pruning at this stage is particularly important. It helps remove dead or unproductive branches, improves the tree’s structure, and enhances fruit production. When pruning grapes, be careful to avoid damaging the plant, and do it early to ensure optimal results.
