According to Colorado State University Extension, "Perennials often require less maintenance than most annual flowers. Once established, they generally require less water than annuals and often have fewer pest problems." Building a perennial garden requires studying your garden site and finding flowers that fit. It means determining how much time you have to spend in your garden before investing in the plants. Amending the soil gives the plants an optimum growing site. Once the perennial garden is established, it is a matter of maintenance rather than beginning anew each season.
Planning the Perennial Garden
Draw a scale model of the planned garden on graph paper. Allow for sufficient room on two sides to provide sufficient access to the plants. Add any established trees, shrubs, fences or other structures to the model.
Watch the sunlight in the garden. Note how many hours of sunlight the different areas of the garden receives and whether it full, partial, dappled or full shade. Also check to see whether the light is morning or afternoon light. Note this on the model.
Use gardening catalogs and books to select potential perennials for the garden. Cut out pictures of the plants and arrange on the garden model. When you have the arrangement you like, glue or tape the pictures to the model.
Planting the Perennial Garden
Prepare the garden soil. Dig it up, remove weeds, rocks and other garden debris. Incorporate generous amounts of well-rotted compost, manure or decaying leaves.
Use a soil testing kit to determine the pH of the soil. Depending upon what plants are going into the garden add sulfur or limestone to change the soil's pH.
Plant the flowers in the perennial garden according to the garden model, beginning with the taller, foundational flowers, then planting the flowers that decrease in height to the lower border plants at the edge. Space all the plants based upon their mature size.
Place stepping stones around the flowers to allow for easy access for care. Lay an irrigation system or soaker hoses around the plants before covering the garden with mulch.
