Yes johhnny you are right. We all have to make the best of what conditions we have. I grow on the equivalent of a sieve. As soon as water is given it is gone. So I water, I mulch, I add bio matter and more water and more mulch and more bio matter. The whole works.
I once heard someone say that if you dig a hole and fill it with water, if the water is still there after 24 hours you have a drainage problem. If I dig a hole and fill it with water, it has gone. I could go on pouring and pouring and it would be gone. Puddling in brassicas? Puddle? What puddle? I blinked and missed it.
I can dig two minutes after it stops raining.
