Imagine for a moment that you have finally got your tomatoes growing so well that the keen gardener up the street comments on them. However after a couple of days of heavy rain your garden becomes water logged and your precious tomato bushes just curl over and die from too much water. Scratching your head you can not believe that too much water was the cause however you soon realize that unless you can find a solution to your drainage problem then you are wasting your time growing tomatoes.
