Please understand, I do not use mulches of any kind. I just passed the data for those who want to use it. I tried organic compost and black plastic, After about 3 weeks I rolled the stuff back, The numbers of bugs and moldy looking stuff I saw under there, I decided it wasn't worth having it around my plants. My thoughts were, I would rather have a little less production than maye the loss of the whole plant(s). My mind wonders how you get enough water with plastic ? By the time you add an underground watering and feeding system, you have added so many $$ to your crop. Is it worth it?? And how do you control underground bugs like cutworm and wireworm. No published data (that I have found) on how plastic mulches affect these thugs. I would also think in the real summer heat that plastic mulches would contribute to plant aspiration. I have yet to see any data on this item. Byron
