How Often to Water A Vegetable Garden

I trust the extension office at the University of Florida. They recently published an article recommending how often a vegetable garden should be watered or irrigated.

Thie article called Florida Vegetable Gardening Guide says this about watering:

Frequency of irrigation depends upon the age of the crop and your soil type.
Young plants need frequent, but light irrigation; maturing crops need more
water,but less often. Sandy soils demand more frequent irrigation than clay, muck
or amended soils. Conserve water by using mulch, organic matter, andtechniques
such as drip irrigation. Make a slight depression at the base of plants to hold
water until absorbed by the soil.

So, I believe I will have my young onions on a twice daily drip for 2 minute intervals.
