Why walnut trees need orchard clearing in early spring
Author: Article source: Agricultural Science and Technology News Published: 2018-02-05 Views:
Answer: Clearing the orchard before walnut trees bud can effectively eliminate many kinds of overwintering insects, eggs and pathogens, reduce sources of pest and disease infection, and lower the overwintering base population of pests and diseases. Combined with early spring re-pruning, remove the grass bundles tied around the trunk and root crown that attract pests for overwintering, clear away overwintering pest cocoons and pupae on the branches, and sweep up diseased and insect-infested debris in the orchard such as dead branches, fallen leaves, weeds and dropped fruit, then bury it deep or burn it in a centralized manner.
