2 kg box of Evergro dolomite lime fertilizer ("for correcting soil pH and a source of calcium and magnesium") http://midislandgardensupply.com/product/evergro-dolomite-lime/ Used a small amount for a science project, and have the rest of the box sitting here. Pick up on the front steps of 1940 Runnymede Avenue! No need to contact me. Happy gardening.
