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. It is possible that you will find winter annuals, summer annuals, and perennial weeds in various stages. If herbicides were used, this information will help determine the need to use different herbicides.
Manage weeds in tree rows. Annual weeds in row middles may be beneficial, but before shaking, manage weeds 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 species and numbers from year to year to better understand ongoing weed control problems such as resistance, and to determine how effective your management operations have been over the long term.
