Seems we either have too much or not enough rain for the garden. Consider installing a rainbarrel to capture rainfall for later use. Wood or plastic, you can find one that blends into the landscape while capturing rain from your roof. Use the rooftop collection to water containers, flower beds and other areas in your garden. You will be amazed at the amount of water you will save by capturing the rainfall that would normally end up in the storm sewer or overworking your sump pump.
