— Research the trees, shrubs and plants you want to use in your landscaping scheme. What will be the height and spread of the plant at maturity? (See following table.) Will it shade out anything else? Take direction into consideration; watch how the sun throws shadows over the course of a day. Don't put tall plants on the South side of smaller ones. Don't plant anything so close to a building that you can't get behind it when it is a mature plant.— Mix species for diversity. This makes a more natural landscape that is less prone to diseases or pests. It also gives you a variety of niches in your garden. For instance, a tall tree might offer welcome shade under which to stretch a hammock on a hot day. Flowering trees welcome Spring with their masses of beautiful blossoms and provide nesting sites for birds. Bush cherries, currants and juneberries with their clusters of fruit offer a smorgasbord to gardeners and birds. A low-growing potentilla hedge gives a splash of yellow color bordering a walkway, while the taller Rugosa rose fills the air with beautiful fragrance all summer. Native dogwoods like red-panicled and red osier dogwood can be difficult to contain, so save them for areas where space is not at a premium.
— For privacy and property line delineation, there are commonly-used northern hedges like highbush cranberry and Peking cotoneaster, as well as more unconventional hedges like hazelbert, juneberry, or cherry Prinsepia.
— Research the particular requirements for each plant in your landscape, for example acid soil, frequent cultivation, full sun, etc.; then place plants with similar requirements adjacent to eachother.
The following table lists the mature height, spread, and shape of
many edible landscape plants, fruit trees, and yard trees.
