The front corner garden needs to be dug out. Then it needs to be replaced. This garden plan gives an example layout, but other types of plants could be used (e.g. low growing shrubs, other perrenials), and also they could be planted in a similar layout to what is presently there. There are tons of other ideas on the interwebs, and I have many more garden plan examples in my files. Whether a garden replacement, or a promise to help me do the work myself, any contribution would make a lovely gift.
