The screened in beds that galanie has are exactly what I want to do.
We did good with our garden down in central TX. Moved here 5 years ago....grasshopper plague just eats everything!! Last year I did not bother with a garden at all between the grasshoppers and no rain. And this year, I may put something in pots soon, but my first batch of chicks aren't due to be hatched until the end of March at the breeder's so I am not planning anything large scale until I see how well the chickens do with grasshopper munching.
One thing I am planning to do, once we get ready to have bigger garden again - probably next year - is to get soaker hoses to run to the pasture where we put the garden. We used soaker hoses underneath mulch at our old house - MUCH better for not wasting water and keeping the plants alive.
My mother and grandmother have had good results in protecting their garden with sheets and sheer curtains they got at Goodwill and making tents over the plants to protect them from the sun. It worked too, they have had some nice harvests with less loss due filtering the sunlight some.
