Survey for Weeds—Late Spring
By surveying weeds in late spring, you can identify species that escaped earlier control efforts, and you will know which perennials are present and which summer annuals are emerging. If herbicides were used this information will help determine the need to switch herbicides.
Weeds in tree rows must be managed. Annual weeds in row middles may be beneficial but before shaking weeds must be managed to provide a clean and smooth orchard floor.
Record your weed observations in order to make weed management decisions. Keep these records so that you can track weed population information from year to year to better understand ongoing weed control problems such as resistance.
How to survey your orchards
Survey information collected over a period of years tells you how weed populations change and how effective your management operations have been over the long term. Keep these records so that you can track weed populations from year to year to better understand ongoing weed control problems such as resistance.
