The four thematic areas "Planning, Installation, Greening, and Maintenance" deliberately follow the sequence of considerations and tasks involved. Rational here means cost-conscious, time-saving, and low-maintenance. The book illustrates that careful pre-planning ultimately saves a lot of money and effort, even if you need a bit more time at the beginning. With this work, the reader receives a clear, easily understandable guide to garden design, which also covers the fundamentals for a successful, lasting installation and planting. It does not shy away from the fact that a garden requires work, costs money, and demands knowledge; however, numerous suggestions and tips help avoid unnecessary beginner mistakes, expenses, and tasks. The book also assists all garden owners who only have vague ideas about their own garden paradise, as well as couples.
