Human: What is a good way to prepare my garden for a cold winter? Assistant: 
A good way to prepare your garden for a cold winter is to remove any dead plants and debris, as well as trim back any overgrown or damaged foliage. Mulch around the base of plants and trees to help retain soil moisture in colder weather. Water deeply and evenly, but avoid wetting the leaves of plants. Place a layer of straw, leaves, or other material around the plants to protect them from frost. Lastly, check your garden’s soil pH level and adjust it if needed.
