Fast Growing Trees

Regardless of the state of your garden, fast growing trees are natures secret to creating a blooming space.

 

Whether you’re starting from dirt, hoping to add instant colour or trying to create more privacy, fast growing trees could be the answer.

 

As there are many tree varieties that grow several feet per year, you have a wide selection to choose from.

 

With the right conditions and pruning, you can easily accelerate this growth and create a garden you’ll love.

 

 

Tree buying basics

Before you rush out and buy any old fast growing tree, it’s worth considering the following:

 

Height

Are planning to plant under a telephone wire or power line? Or does the potential spot have unlimited headroom?

 

Canopy

How wide will the tree grow? Will it spill over into your neighbour’s garden? When grown, will it cast a lot of shade?

 

Growing space

Your tree might be tiny today, but it will grow and some can spread their roots and branches far and wide. Could roots damage walls or patios? Will falling branches damage buildings or cars?

 

Your environment

Your soil, sun coverage and water will differ depending on where you live. So it’s worth researching if your selected tree can thrive in your garden’s conditions.

 

Reason for planting

Are you after more privacy? Year-round colour? A hub for wildlife?

 

 

Should you plant native species?

The Woodland Trust recommends planting native fast growing trees. These trees are always a good bet as they are accustomed to our weather and soil. Trees from colder climates are also good options.

 

Ecosystem benefits

By planting native trees, your local ecosystem benefits. They provide protection and shelter for many birds and mammals. Their nuts, seeds, and fruits are essential food sources for British wildlife.

 

Low maintenance

Once rooted and growing, native trees require little maintenance, special treatment and less water.

 

Cuts CO2

Certain native trees help to combat climate change by effectively storing carbon dioxide.

 

Reduces flooding impact

If you live in an area prone to flooding, trees protect soil from erosion, reduce surface run-off and slows flood waters.
