We stress trees and palms which not only grow but grow more valuable over time. Planting a fine palm creates a special unique landscape while year after year adding significant value to your property. Common plants add far less value. For example, always extract black olives, most ficus and all shefflera trees. Just get rid of them all now .
Most home owners sweat the small stuff - like shrubs and hedges and flowers .
These plantings are relatively unimportant. Shrubs and flowers are cheap and are easily replaced. Unlike trees and palms, growth over time rarely enhances their value significantly. Don't jam plantings so close they will interfere with each other as they grow. You don't use more fertilizer.
