Tom said:It is pretty common for the parts of the pad touching the ground to start to rot if people water too early or too much. I've had this happen. It seems to be working fine for you, but I thought it would be good to mention to the masses, that they generally should not be watered for about a month after planting, depending on your climate. A month works for my area with very low humidity. One could probably go longer in areas with higher humidity.
