I won"t get back home in time to bother with a garden this year, but I want to get it ready for next year. I am planing to put in drain tile as it get soggy in spring sometimes, delaying planting. It"s 100x100" roughly, and I was planning on putting in tile around the perimeter and two or three cross sections. I"ll be using the tile with the silt sock on it. The garden is fairly flat with just a slight dip in the center. I"ll put a sump pit at the low spot so I can pump out water. My subsoiler will go 10-12" deep, so I"m planning on putting the tile around 16". Am I on track here? I"ve not used tile this way before, so I"m just checking. BTW, it"s plain Ohio clay soil, and I"ll be adding some compost on top, about 1".
