How to Plant Flowers in a Container Garden


Container gardens create a beautiful environment for outdoor living areas or on patios with limited space. Take advantage of small spaces by creating a container garden on indoor windowsills or in front of large windows. Choose annual flowers in a variety of colors and heights and place the planting containers in sets of three, as odd numbers of containers are more visually appealing. Mix herbs with the flowers to create a container garden that is attractive and useful for cooking.

Step 1

Select planting containers that are 2 to 3 inches larger in diameter than the flower root balls and have bottom drainage holes. Drill three to four drainage holes 1/2 inch in diameter into the bottom of decorative containers that do not have bottom holes.

Step 2

Fill the growing containers two-thirds full with a well-draining and nutrient-rich potting soil. Moisten the soil with water to dampen without saturating.

Step 3

Set the flower root ball in the center of the growing container so the top of the root ball is approximately one inch below the lip of the container. Fill the container with potting soil to the top of the root ball and gently pack to hold in place.

Step 4

Arrange multiple flowers in the container by placing tall growing plants in the center or rear and low growing or hanging flowers around the edges. Set the plants so the root ball is approximately 1 inch below the lip of the container. Fill soil around the flower root balls and gently pack to hold in place.

Step 5

Water the flowers after planting to moisten the soil until water flows out the bottom of the container. Continue to water the flowers every one to two days to keep the soil moist during the hot summer months. Monitor the soil moisture because container plants dry out faster than garden bed plants.

Step 6

Fertilize the flower containers every two to three weeks with a water-soluble flower fertilizer. Follow the package application instructions for the size of the container needing fertilizer.

Step 7

Place the container on a drainage saucer or elevate it on blocks of wood to open the drainage holes and prevent oversaturation. Set containers with full sunlight plants in an area that receives a minimum of six hours of direct sunlight each day. Morning sunlight is preferred because it does not dry the soil as quickly.
