In our garden, not just on the vegetables, my dad has this habit of hoeing the soil, but very vigorously. He takes the hoe and just goes all around the plants and bare areas uprooting soil to a depth of 2 to 3 inches by slamming the hoe into the ground repeatedly. Sometimes to more depth depending on the hoe used. Is this really necessary? Its being done very often like every week. I told him to stop dong it but he wont listen. I think he destroyed several perennials (unknowingly) because they got uprooted by the hoe before they started growing at the beginning of the year. I think its wrong and not necessary, although I'm not really sure. Our garden is composed of different types of soil types (clay, sandy, etc. depending on the area and what is growing there) but this action of hoeing is taken everywhere regardless. Any thoughts?
