Everybody knows that soil is the foundation for tree growth!

However, not all soils are the same, and that can have a significant impact on the trees growing from it.

Cultivating the right kind of soil will ensure trees will live and thrive, even in urban locations where there is less room for them to survive.

That’s why it’s so important to take note on what’s happening below ground, if you want to enjoy the beauty and shade of the greenery above.

Let’s take a closer look at soil and its importance for healthy tree growth.

What makes up soil?

Soil is composed mainly of elements like water, minerals, nutrients and gases.

Different types of soil vary according to texture, colour, depth, acidity, fertility and ability to hold water. Because each tree species has different needs, it’s crucial to know what kind of soil they require to grow – if you want the best results.

To help familiarise yourself with the varieties of soil, here are the most common types of soils you need to remember:

  • Chalky – a stony type of soil that can be found on top of limestone or bedrock
  • Clay – a tightly packed soil that is often lumpy and sticky when wet
  • Sandy – dry and loose soil base that has a rough texture
  • Silt – smooth, slippery kind of soil that is composed of fine particles
  • Peaty – contains a great amount of organic matter due to its acidic nature
  • Loamy – the best soil for planting, as it’s full of nutrients and can hold water well

Why is soil important for tree health?

The soil you use can either nurture or restrain your trees’ growth because soil performs a lot of essential functions. Here are the five reasons why soil is important for trees:

  1. Soil provides a foundation for tree growth.
  2. Soil stores the necessary amount of water for trees.
  3. Soil hosts biodiversity.
  4. Soil supports the trees’ roots in accessing nutrients and minerals.
  5. Soil filters out the pollutants that can harm trees.

In urban locations where healthy soil is not abundant, it’s important to ensure that trees are planted with the appropriate soil structure to compensate – often called the “architecture of the soil.”

Having the right soil architecture guarantees that there is proper arrangement of soil particles (including silt, sand and clay that aggregate together). It also involves measuring the correct pore spaces between each tree, which enables their roots to propagate without causing any structural pavement damage.

When these two considerations are overlooked, trees will struggle to grow in city and suburban locations, leading to replacement and maintenance costs, unsightly spaces and poor shade quality for the community.
