I have an area about 2' X 40' that gets maybe 2 hours of midday sun each day. The ground is clay. 1. Do you think Pachysandra will thrive in this area as a ground cover? 2. What would I need to do prepare the ground besides running a rototiller through it? Thanks for your help, Ralph Mayer
Amending the clay soil is an option and good idea to optimize the plants you can grow and the success of what you do grow.
Some options for your area may include Creeping Jenny, Snow on the Mountain, Canada Violet, Beacon Silver.
Pachysandra plantings would thrive in a more loamy, well draining soil.
Here are some links to help you.
