Inge asked: I have an old tree in front of my home. I like to add a flower bed around the tree, but I am new to planting and gardening. Also, my lawn needs a lot of care. Last year my husband tilled part of our lawn and we replanted new grass, but our lawn looks very unhealty with a lot of try, burned like spots. What can I do to have a healthy lawn, and how do I go about creating my flower bed around the tree. I like to put a border around the tree like a small wall maybe. I want the flower bed be higher than the actual lawn. We have mostly clay dirt. Can you give me some advice and/or help. Thanks.
