I,m going to fill in some shady spots by planting Dutch White Clover. Can clover be fertilized along with my lawn fertilization process...3 times a year? I live in north central Minnesota.
Some hardy varieties can tolerate light fertilization, but most won't tolerate that much nitrogen. They extract their own atmospheric nitrogen. The only thing to do will be to plant a few patches and see if they survive, until you find a cultivar that is not sensitive to feeding.
