WOW--I read those posts Rick. Thanks for your persistance on the perched water table subject. And here I've such such a diligent student of the 'old school' procedure all my life for something probably more harmful than helpful--and doing such a nice neat job of it at the same time as well. Well, anyway, the old way must have worked for me ok because I never had any real problems--but who's to say it coudn't have been better. I compose my mix to have good drainage anyway and have often thought about not using it. I'll run without it next year--at least on some!
