Clay soil? No problem! How to amend it and what to plant in it

If you need a jackhammer to bust into your soil, you've got clay. If you dig a hole and fill it with water and it doesn't drain, you've got clay soil. If you pick up a chunk of your damp soil and it feels like you could use it for a ceramics class, you've got clay soil. Although it can be frustrating at times, clay soil can actually be your friend. We promise.
