Is it a good practice to apply salt to an asparagus planting?
In the past, some gardeners used salt to control weeds in their asparagus plantings. However, salt is not effective in controlling many weeds, especially grasses. Plus, continued use of salt over several years may result in high salt levels in the soil. High levels of salt may actually damage the asparagus. In the home garden, shallow cultivation and hand pulling are the best ways to control weeds in an asparagus planting.
