|What is the best planting mixture for container gardening?|
|Potting soil is the best growing medium for container plants. It drains quickly yet holds just the right amount of moisture for plant roots. You can purchase a good grade of potting soil for your containers, or, if you have lots of containers to fill, you can mix your own.
Here are two recipes: Basic Peat Mix (makes one cubic yard) 1/2 cubic yard of sphagnum peat moss, 1/2 cubic yard of vermiculite. Mix together well; then add: 5 pounds dolomitic limestone 1 pound superphosphate 2 pounds 5-10-5 fertilizer. After mixing thoroughly, store in plastic bags. Moisten mix prior to use. Here's an organic version of soilless mix: 16 quarts of sphagnum peat moss, 16 quarts vermiculite, 7 ounces bone meal, 3 1/2 ounces dried blood meal, 3 1/2 ounces ground limestone. Mix thoroughly and store in plastic bags. Moisten mix prior to use.
