A circular bed is an eye-catching feature for a flower garden. Perennial and annual flowers are planted to create a bed filled with blooms. Soil for the foundation of the bed can be formed in a mound, flat, tiered or raised bed shape. The flower garden can be designed in a round shape such as a wheel, smiley face or series of rings. The circular shape is easily adapted to a small or large flower bed.
Draw a circular shape on a piece of graph paper. Jot down the measurement for the width of the circle of the garden bed. Each square on the grid will represent a portion of that measurement. Draw the pattern that you have chosen on the circular shape. This will help you to decide how many plants you need and how far apart they will be planted.
Measure the width of the circular flower garden space in the area where it is to be planted. Insert a stick into the area where the centre will be. Tie a cord to the stick and mark the circle by walking around the stick while shaking out a line of flour.
Dig up the soil with a spade. Remove any stones from the area. Set the stick back into the centre of the circular flower bed. Stretch the cord out to the circle edge to use for a guide.
Following the pattern guide on your graph paper, start at the middle of the circular garden and dig a small hole for the first plant with a garden trowel or the spade. Choose one of the taller plants or a rosebush for the centre planting and set it into the hole.
Pull the cord out in a straight, taut line to keep rows of plants even. Dig the holes according to the design around the circular bed for each plant or seedling.
Build the circular flower bed in the autumn with spring bulbs. After the flowers blossom fill in the area with annuals for a spring and summer garden.
