Gardeners who enjoy container planting have a wide variety of containers from which to choose. When you choose a concrete planting container for your landscape plants, you have a strong and sturdy container that will withstand the elements without toppling over. You also have the added benefit of being able to place your concrete container anywhere without worry that someone will walk off with it. Plant in concrete containers for an attractive landscaping look that will stand the test of time.
Position your concrete container in the location you desire. Because concrete is so heavy, do not plan to move the container after you fill it with potting soil and plants.
Cut a piece of landscaping fabric to cover the bottom of the container. This will prevent soil and gravel from flowing out the drainage hole.
Place approximately 2 inches of gravel in the bottom of the concrete container.
Fill the container about 1/2 to 3/4 full with potting soil.
Remove the plants from their temporary containers carefully. Place the plants into the concrete container so the crowns of the plants are about 1 inch below the rim of the container. Add more potting soil to the container if necessary so the plants will be at the proper height.
Fill the container with additional potting soil so that the soil is full and firm between the plants. Add approximately 1 inch of potting soil over the plants at the top of the concrete container to finish the planting process.
Water the plants generously immediately after you finish planting them.
Add a light layer of decorative mulch over the top of the soil, if you wish.
