i just tested the ph on my bag of miracle grow potting mix. ORANGE! thats between a 3 and 4 on my kits scale. 7 is neutral. check their website. many people are having problems this year with yellowing leaves and stunted growth. screw MG. costing me time and money. serves me right buying...
lets not forget that 1420 was a good year in the shire for long bottom leaf. tolkin was also writing long before 1970. or maybe i just have a gooder imagination. :)
