Make a simple drawing in your journal to show location and names of any plants that are part of your project. You will want to go a step further and plant grass, flowers, shrubs, or trees. Get the right plant in the right place. You need to know how tall and wide a tree or shrub grows. Plants should fit in with existing plantings and not just stuck anywhere.
Many urban soils are shallow and of very poor quality.
To grow plants these poor sites must be modified. Good top soil is often impossible to find in the city. The addition of compost adds nutrients, loosens the soil allowing roots to grow, absorbs water for future growth while allowing excess water to drain away. Organic mulches are also important in moderating the environment of the plant's root system. Ask for help as soon as possible to get the most benefit from their knowledge and experience.
