|when i walk into the HD there are so many different types of soils, my head starts spinning!
What is topsoil? Manure...Composted Manure? Seeding Soil?
|All of the packaged soil mixtures are designed to improve your garden soil. Topsoil is a mixture of garden loam, sand and organic matter such as peat moss; manure is typically cow manure with straw; composted manure is cow manure and straw which has been weathered and heated to the point where weed seeds are killed; seeding soil is a fine textured mixture of organic matter which makes it easy for newly germinating seeds to penetrate and grow a healthy root system.
Each packaged soil mixture has a specific purpose. If your garden soil is hard clay and does not drain well, you can add topsoil to your garden. You spread it on top and dig it in to a depth of 8-10". This will help loosen the soil and make it drain quickly enough to keep the plant's roots from becoming waterlogged. Manure and composted manure are used in the same way. Seeding soil is spread in trays or flats or pots and seeds are planted in it. Keep it moist and the seeds will sprout and thrive.
Hope this answers all your questions!
