When is the right time to fertilize the green trees (when to water and fertilize the green trees)

1, basal fertilizer should be applied before germination in spring or after defoliation in autumn, and appropriate topdressing should be applied in June, July and August in the growing season.

2. The absorbed nutrients and water are in the fibrous roots, so fertilization should be around the roots, not near the trunk. For trees with strong roots and far distribution, fertilization should be deep and wide; Trees with shallow roots should be lightly fertilized, and nitrogen fertilizer has strong fluidity in soil, so shallow fertilization can penetrate into the root layer and be absorbed by trees.
