Do not expect to be reimbursed should your plant die from neglect. Buy hardy material that is adapted to your area. A good way to plan your yard is to visit an attractive neighbourhood. Make a note of the names of the plants you like. If you cannot identify a plant, ask the home owner.
Most people are happy to talk about their favorite tree or shrub.
Note how people use particular shrubs and trees on their property. If you like the plan, you might adopt it. Note also how far trees or shrubs are planted from each other, and from the house or fence. Often young plants are planted too close for proper development. Find out how large a plant will be when it is fully grown.
