Advantages of Planting Shrubs - Shrubs For Zone 4
Shrubs are usually described as plants with many stems that do not generally grow above fifteen feet; some bushes can grow to larger sizes, such as the forsythia that can rarely reach 18 to 20 feet. A bush differs from trees in most trees grow from a single thick trunk and have an extensive root system of up to three times their large canopy. The thick, woody roots of the shrub can have an advantage over other types of plants in the long term as they compact soil and increase the number of nutrients within the earth.
When plated on a slope a shrub, such as the burning bush can have a positive effect on the soil by compacting it and helping stabilize the ground and stop it sliding off the surface and down the slope. The burning bush is a native of the US and Canada and provides interest in a yard because of the purplish-brown twigs and stems. Larger shrubs are also used to screen and hide areas of unfinished or unattractive areas of a yard or recreation area from view. Many of the world's population of the shrub are deciduous, meaning they protect areas of a home or building from the Sun in the Summer months and allow sunlight through to heat areas when the Winter arrives, and the leaves have been shed.
When an area of ground has been damaged, or its nutrients have been used up, and it is a problematic growing area the plating of a shrub can help bring the city back to life as a growing region of a yard. Not only can a bush increase the nutrients in the soil, but it can also reduce the number of chemicals harmful to other pants. In parts of British Columbia, a native shrub can draw nitrogen into it and reduce the amount found in the environment. One of the primary reasons for planting plants of any variety in a bare area of yard is that soil not used for plants, grasses or trees can become compacted and lose its fertile nature; a shrub, like blue hydrangeas planted in a yard, can fill a barren area quickly with large blue flowers known in some regions as mopheads. Blue hydrangeas can grow to enormous sizes and cover the ground of a tract of land with the most attractive flowers that have made the shrub one of the most popular plants in the world.
Many people plant a tree or shrub in their yard to encourage wildlife to visit, feed and breed in their gardens. Planting a forsythia, which generally grows to around nine feet and is a member of the olive family can provide food and a place to shelter for wildlife including squirrels and birds who visit most yards.
