Im doing an introductory presentation on organic lawn care for garden club at a good sized park here in Chicago Saturday. Expecting a good sized crowd with a little blurb in the Trib and lots of local interest. Daley, for all his faults, really does encourage green issues in the city and local parks with gardening programs have lots of interest in organic lawn care. Lawns in the city are small small small. 1500 sq ft. maybe so its impossible for me to make money in the city, I have to hit the burbs. Anyway Im just expanding on my customer pitch essentially but getting into more specifics. Just wondering what pearls of wisdom some of you might impart to an audience if you had the chance. Im covering turf culture, weed/disease control, fert options, composting, tea, and sustainability beyond organics-turn your landscapes into waste eaters rather than waste producers ( my fav ). Like I say its first time out for me so if any of you have thoughts about what a varied audience of potential green lawners might need to hear drop me some wisdom.
