10 Tips to Manage a Sustainable Urban Garden
Know your soil conditions.
Many urban gardeners are correct in thinking they have poor soil. The urban garden area is likely to be compacted and poor in structure and quality.
Once you have selected a garden area, test the soil to determine the soil type, pH, organic matter content, and available phosphate and potash. You can buy soil-testing kits at garden centers or send a soil sample to a soil-testing laboratory.
The key to improving the soil is to do it before you begin any planting. If you incorporate the proper amounts of organic matter and soil amendments, your soil will provide nutrients and make air and water more available to plants.
