Plants need water, light, the proper temperature and occasional fertilizer. But all the nurturing in the world won't do any good without a solid foundation. Host Paul James and Norm Ross, plant manager at Whitney Farms, give gardeners the dish on potting soil."Potting soil isn't dirt," says Ross. "It's made up of amendments." According to Ross, great potting soil is similar to a time-honored recipe, and to achieve the best results, you need to start with the best ingredients. "I look for a good mix of peat moss, also compost, fertilizers and some pumice for aeration of your potting soil."
Soil recipes and amendments vary according to location and utilize raw materials from different regions. Soils may also be specially mixed with certain plant needs in mind. "You'll find all types of potting soil for all types of plants," says James. "For example, there's an African violet mix, an orchid mix, a cactus mix, a bonsai mix--all geared to meet the needs of whatever you're planting."
