When is the best time to fertilize pruning fruit trees
Summary: The knowledge content about when is the best time to fertilize pruning fruit trees, as well as the best time for top dressing fruit trees, will definitely help you. Let's learn about it together!
1. Early-stage fertilization time for apple trees: Apply fertilizer before flowering or at the germination stage (in early April); apply fertilizer after flowering (in mid-May). These two fertilizations in the early stage can effectively promote tree germination, flowering, and prevent the loss of nutrients due to flowering, improve fruit setting rate, and promote the growth of new branches.
2. Mid-late stage fertilization time for apple trees: Apply fertilizer for flower bud differentiation and young fruit expansion (from late May to early June). This top dressing is to meet the needs of fruit expansion, branch and leaf growth, and flower bud differentiation. Usually, potassium fertilizer is the main type of top dressing for apple trees.
3. The best period for applying accumulated fertilizer for apple trees is generally in autumn (from early to mid-September). Accumulated fertilizer for apple trees mainly consists of farmyard manure, and phosphorus fertilizer is applied in full amount for the whole year. To fully utilize the fertilizer effect, phosphorus fertilizer should be堆积ed and matured with organic fertilizer first, and then mixed and applied.
4. The main function of applying accumulated fertilizer for apple trees is to ensure photosynthesis of the trees from after harvest to before defoliation, improve nutrient accumulation, and lay a good foundation for the growth and development of the trees in the following year. Based on these four fertilizations, it is also necessary to consider combining foliar spraying with melon and fruit stem strengtheners. Before July, spray 0.3% to 0.5% urea solution + melon and fruit stem strengtheners, and after July, spray 0.3% to 0.5% potassium dihydrogen phosphate or trace fertilizer for fruit trees + melon and fruit stem strengtheners.
That's all for the introduction of when is the best time to fertilize pruning fruit trees and when is the best time for top dressing fruit trees. I hope it can be helpful to you. Don't forget to check out more experience and common sense!
