Good soil is the basis of every landscape success. Most of us are not blessed with good soil – we have lots of clay, which holds WAY too much water.
Here is what I do to build the soil in my beds.
1 part clay or existing soil
1 part coarse sand
(such as the gritty paver leveling sand available from home improvement stores)
2 parts soil conditioner
(you can substitute 1 part composted cow manure or mushroom compost for 1 part of the soil conditioner)
Mix it all 10″ – 12″ deep and you’ll have soil any plant would be proud to call home.
