Destroy them so that the vegetables develop properly. Generally, practice shallow cultivation. After a vegetable plant has obtained good size, many of its roots are in the upper two inches of soil.
Deep cultivation injures roots and decreases growth and yield.
Early in the season following heavy beating rains, cultivation is a means of loosening and aerating soils. Deeper cultivation can be practiced at this time. As the season advances, cultivation should be only deep enough to control the weeds and keep a loose soil mulch on the soil surface. Watering the Garden Water is a must for the garden to produce good quantities and quality vegetables. When irrigating your garden thoroughly, wet the soil at least once a week unless there is sufficient rainfall to moisten the soil around the roots.
