Maintaining a garden of container plants is a good way to enjoy gardening when you lack the yard space. Container gardens are popular in apartments, homes with small yards and as kitchen herb planters for ease of access. Filling a planter is a simple process, regardless of the type of plants that will grow in it.
Place the planter in your windowsill or on your patio. If you live in an apartment with a balcony, you can place the planter box on your balcony floor.
Place the thick plastic sheet into the planter, smoothing it up the sides of the planter as well. This is to hold in moisture and prevent the roots of your plants from escaping through the bottom of your planter box.
Cover the thick plastic sheet lining the planter with a 3-inch layer of sphagnum moss. This will be used to retain moisture for the health of your plants, because planter boxes often lose moisture quickly.
Cover the moss with potting soil. Fill the planter only halfway full, leaving a big enough space for the plants to sprout and grow.
Plant your choice of seeds in the planter whether they be flowers, herbs or vegetables. You can even plant small fruit trees in planters.
