Vegetables perform best when receiving at least 1 inch of rainfall or irrigation a week.
There are a couple of things to consider when growing your first vegetable garden as well.  All vegetables prefer full sun and well-drained soils.  Vegetables perform best when receiving at least 1 inch of rainfall or irrigation a week.  And vegetable gardens need to be regularly weeded to prevent competition from weeds for light, water and nutrients.  And lastly, most vegetables have fewer disease problems when rotated to a new site each year.  Therefore, all vegetable gardens require planning prior to planting and regular maintenance each week during the growing season to be successful.
