Arranging flowers for container gardens often has a surprise element, particularly if you are planting flowers that are new to you. Usually you plant flowers when they are small and sometimes before they flower. The blooms are like little presents, and the way those flowers work together in the arrangement crates the wow factor. When an arrangement really works, you'll have a sense of enormous satisfaction and, of course, you get to enjoy and share your container success with your friends and family.
Select large containers. Plants need less water and tend to thrive better in large, well-drained containers.
Line the bottom of the container with 1 to 2 inches of gravel so that the flowers will have adequate drainage.
Mix potting and gardening soil together. Sometimes potting soil alone can be too light, and a blend will often need less frequent watering. Fill the container to 1 inch from the top.
Divide your flower selections into sun-loving flowers and shade-loving flowers and plant each type in separate containers.
Select colors that are themed. Consider placing a tall, blue-flowering plant at the back or center of an arrangement, surrounded by smaller white flowers that bloom prolifically. The combination of blue and white will look stunning.
Select flowers based on height, spread, vibrancy, durability and cascade effect. Plant containers that people will only view from one side by placing large and tall flowers to the back with medium and spreading flowers in the middle and cascading and smaller flowers up front. Use your gardening trowel to remove enough soil to insert the plant ball. Remove the plant from its shipping container, loosen any tight roots and pack the soil firmly around the root ball. The top of the root ball should be level with the dirt in the container.
Insert large, round, flowering plants in the center of a large round container. Skirt the center plants with filler and wide spreading flowers with vibrant color. Fill gaps with smaller complementary flowers and finish with flowering plants that will dangle over the edges. Round containers are usually meant to be viewed from all sides.
Water containers immediately and well. Flowers experience a lot of shock when you transplant them. Use a mild fertilizer designed for container flowers to feed your flowers every week or two. Make sure your flowers have the amount of sunlight they need to flourish.
