Choose pots that are large enough for your plants. Roots need room to grow. Read plant labels for growing needs. Fill in with additional soil up to one inch below the pot top. Mulch with hardwood mulch or pebbles.
Pots dry out faster than soil in ground-level beds, especially quickly in the summer.
Double-potting is one way to conserve moisture, especially if you use clay pots, which dry out quicker than plastic, wooden or ceramic pots. To double pot, place a pot inside a larger pot with a layer of gravel around the sides and bottom to separate. To protect potted plants from winter winds and cold, wrap them with bubble wrap, sheets of foam or lengths of burlap.
