ROADSIDE
PLANTATION
Planting trees along the roads and highways has been practised from
ancient times in countries throughout the world. For good roadside planting,
trees suitable for local ecological conditions should be selected. They
should have spreading, dense, shapely crowns and preferably showy scented
flowers. Fruit trees should be avoided as far as possible. To maintain
uniformity a single species should be planted over a long stretch of
road.
