Survey for Weeds—Late Spring
By surveying weeds in late spring, you can identify any species that escaped previous control attempts and determine which perennials are present. Ideally tree rows are weed free, whereas weeds growing in row middles can reduce water quality problems by preventing soil erosion and water and sediment runoff to creeks and streams. However, perennial weeds are problematic and should be kept from establishing in row middles.
How to survey your orchard
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.
