If you're preparing a new planting bed, start by amending the entire planting area by thoroughly tilling two to four inches of mature compost into the upper eight to twelve inches of soil. In addition, an organic fertilizer worked into the planting hole will promote healthy soil life and release nutrients gradually over a long period of time. If you suspect a mineral deficiency or have a particular soil problem you may wish to have your soil tested by a lab service before amending. Home or lab test results can help you, with the assistance of a nursery or landscape professional, determine any additional amendments needed. If you are undertaking a large project, check the business listings in your phone directory under Landscape Equipment and Supplies or Topsoils and compare prices and minimum load quantities for delivery.
Organic fertilizers are available at most nurseries and garden centers.
Unhealthy plants are generally more susceptible to pests and disease. Planning a great garden starts on paper. Map your yard, identifying the site conditions mentioned above. Remember that all plants need regular watering until they are established - from one to three years. By using the right plant in the right place, in combination with good soil preparation and mulching practices, your landscape should need relatively little supplemental watering after establishment.
