Amending Your Raised Bed Vegetable Garden Soil (Yearly!)
Amending Your Garden Plot with Peat Moss and Humus (Moisten!)

This is a large container that is probably 25 gallons. Peat moss is hard to moisten because it floats. Fill your container halfway so you can reach your arms into it and turn it easily. Put in a good amount of water and then mix by hand. The trick is to sort of pet the peat moss in big circles. This rolls the water and peat moss together. Just mixing it under doesn't work. You have to rub the particles into the water. It is THAT DRY! The peat moss should be moist not soggy. When you squeeze it, water should not run out of it.
