Structural Soil for Urban Trees

Structural Soil for Urban Trees

Currently most urban trees are planted directly into existing compacted urban soil or tree pits with limited root space. Trees that are planted in areas surrounded by paving tend to struggle for air space and usually decline well before they should. Where soil volume is limited by pavement, tree roots suffer and tend to take the path of least resistance searching for air, usually in and around pipes, foundations, or to the surface. Healthy trees need a large volume of non-compacted soil with adequate drainage and aeration and reasonable fertility.structural-soil-expanded-view

While the need and desire for large trees in the urban landscape still is the desired intent, the trees do not survive long enough to fill the need. Not planning for root growth is ignoring the biological requirements of trees and is not economical or environmentally prudent. The failure to provide adequate soil for both drainage and root growth is critical to the life of the tree and without an engineered soil specific to this application, trees have a shortened life span and may die. Ensuring a good supply of air to the tree roots is essential for satisfactory tree growth, however in urban situations, the movement of air into the soil is often restricted. By providing additional root space below the pavement in what otherwise was compacted urban soil, Structural Soil can allow most newly planted trees to have a chance for healthy growth. This mix consists of 80% 75 mm angular clear aggregate  and 20%  approved sandy clay loam. The aggregates bear the load, providing the structural stability for the pavement above. The angularity of the rock create for the non-compacted soil, providing space for air, water and nutrients the roots, as well as provide for future root expansion. Engineered structural soil provides a resource for root growth beyond the traditional tree pit, allowing for much stronger root growth and ongoing tree health. Bitter_orange_-_Citrus_aurantium_08

Denbow has been providing structural soil to many municipalities within the Greater Vancouver and Fraser Valley area. These departments use Denbow’s manufactured soil to allow city planners and engineering departments to add trees for the health and beauty of urban communities.

Best Types of Compost for Landscaping – Ask Tom

Best Types of Compost for Landscaping – Ask Tom

What types of compost for landscaping?

There are a number of beneficial composts available for the local landscape projects, and the choice should depend on what the compost is being used for.

So what are the best types of compost for landscaping? There are composts  in the  marketplace that are specifically based on mushroom manure which is plentiful in our area. Mushroom manure can be useful but it can also be overused.  Clean green compost, which is made of clean green waste and debris, is one of the more pristine composts in our marketplace. Other large sources of municipal compost are available and; those are appropriate for certain uses, typically larger remediation and possibly landscaping.soil-in-hand-1

How do you know you’re getting good compost?

Good-quality compost has a number of characteristics. It’s usually brown and black in colour, but the colour is just one benchmark. The compost should have a reasonably good earthy smell, not an overly rotten smell like manure. Also important is the supplier should have an analysis available. Quality suppliers will regularly have their product tested and have soil analyses available for the end user.

Why is compost an important part of the soils being used?

soil-in-handCompost-based soils made with clean quality compost should be the top choice for landscape projects.

Compost is the important organic matter that helps the soil to function in a number of ways. It provides water-holding and nutrient capacity, providing for overall plan health.

Be selective when specifying or purchasing manufactured or engineered soils; for many projects, the best or only opportunity to provide plants or seeds with the best nutrition is during the initial installation.
