Tree and Shrub Material for Urban CentresBareroot seedlings of caragana, green ash, Manitoba maple, Siberian elm (Saskatchewan only) and Villosa lilac are available to cities, towns and villages for perimeter plantings on public land. Although the seedlings are not suitable for boulevard or ornamental plantings, they will provide excellent shelter when planted as perimeter shelterbelts. Perimeter plantings usually consist of one to three rows of trees. The outside row should be a shrub - caragana or lilac. The shrub row will act as a snow-catch and provide wind protection near ground level. The second row should be a tall, long-lived tree such as ash or maple. This will give height to the belt and provide shade in summer and additional wind protection year round. The inside row could be either a tree or a shrub, depending on the purpose and location of the planting. It is important that a minimum distance of 16 feet be left between rows to allow for cultivation.Along with perimeter plantings, field shelterbelts planted along the main roads near towns and villages will reduce snow clearing costs and ensure all-weather access to major highways. Trees may also be planted to beautify town entrance lanes, garbage dumps and sewage lagoons. The planting site should be well tilled and free of weeds and grasses for at least one year prior to planting the trees. The seedlings are approximately 12 inches in height and cannot compete with weeds and grasses. Maintaining the shelterbelt in a weed-free condition ensures that the seedlings get the sunlight they require and allows them to make use of available soil moisture and nutrients. The young seedlings should be thoroughly watered immediately after planting. If it is possible to water the seedlings during hot, dry periods in the summer, their rate of growth, health and vigour will be increased.
