Survey Weeds—Fruit Development
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 may be beneficial in reducing erosion,
soil compaction, water runoff, and sediment runoff to creeks
and streams that ultimately impairs water quality. However, perennial
weeds are problematic and should be kept from establishing in
row middles.
How to survey your orchard
- Survey your orchard in late spring or early summer, after summer annuals
have germinated.
- Check for regrowth of perennials a few weeks after cultivation.
- Sketch a diagram of the orchard and mark areas where perennials are found.
- Keep records of your survey results for future management
decisions (sample late-spring
weed survey form—.
Survey information collected over a period of years tells you
how weed populations may be changing and how effective your management
operations have been over the long term.
By knowing which species are present, you will be able to make
appropriate decisions on cultural and chemical controls.
