All 19 years that I ran my organic landscaping business, THE GARDEN DOCTOR, here in Tampa, central to making my customers' yards successful was a liberal annual application of dolomitic limestone. Not long after I first bought this place in 1998 my front yard alone got 800 pounds of it. My back yard these days has several quite large Water Wise Container Gardens on the east side, 18-55 gallons, all filled hugelkultur style, with the soil coming from the free range chicken path, which over the years have been top dressed with a vast number of bags of gathered acidic oak leaves plus stable waste. Some feature color source plants, some have what Allen Boatman and I years ago named "Filipino Mexican Tree Pepper"....all have gotten fish emulsion, Epsom salts, chicken poop, plus I pee in them. But the plants all just sat there, especially the hot peppers plants, month after month. I was perplexed, but then realized that never ever had I applied dolomite to the chicken paths, so from Lowe's I bought a bag horribly labelled as "Pelletized Garden Lime" since at my Home Depot I could not find the Sunniland brand I had bought so many bags of years ago. I gave each of the containers two big handfuls and watered it in...this was a little over three weeks ago. Everything responded very well but ESPECIALLY the peppers who had barely grown at all for months. They are now 4 times the size, and those tiny leaves are now as big as my hands! And now the older one suddenly has peppers. I am surprised that I had slowly forgotten just how wonderful a garden aid dolomite is since I wrote about it for eight years in The St. Pete Times to reduce acidity while supplying calcium and magnesium. So time for me to buy quite a few bags for my beds....it is a rock powder....I think I spent $4.29 for a 40 pound bag at Lowe's.
