In The Garden: National Tree Day

Plant a tree on September 26th

After much debate, a bill was passed in the House of Commons in 2011 to create a National Tree Day each year, which falls on the last Wednesday in the month of September. This year, that day is September 26th. Tree advocates everywhere can now breathe a breath of fresh air.

The Right Time

September is the best time of year to plant. You may choose to do so on National Tree Day, or any other day in the near future. However, I urge you to plant – more than one tree – and soon. The cool evening temperatures slow the growth on the top of the trees, while the warmth of summer still radiates in the soil and encourages young feeding roots to develop. The development of autumn-planted trees usually outgrow those that are planted in the spring. Come spring, your results will be nothing short of spectacular.

In addition, most retailers are clearing out their inventory at this time of year, so there’s an extra incentive to select the trees that you really want at a fraction of the cost – fruit trees, shade trees, ornamental flowering trees, native trees and shrubs.

Plant Native

Whenever, and wherever, you can plant native trees – it just makes sense. For the most part, native trees adapt well to our urban environment, they self propagate, and are disease and insect resistant. In addition, they attract nesting song birds. LEAF (Local Enhancement & Appreciation of Forests) is a non-profit organization dedicated to the protection, and enhancement, of the urban forest. Visit for programs and advice on making the right choice for your environment.

I recommend starting with a nursery-grown native plant. They are properly cared for while developing – after all, they are called nurseries. A field-grown tree will be root pruned before being lifted out of the ground. A container-grown tree will have all of its roots intact at the time of planting. As a result, you’ll be pleased with your investment, because it should be a seamless transition between the nursery and its new home.

Deciduous Dedications

A country-wide tree day could not exist without official tree plantings. Visit for listings and events going on in your area. Or, better yet, create your own event and register it on the site.

On September 26th do something for yourself, for your grandchildren, for your community and for the environment. Plant a tree on National Tree Day, and celebrate the great work that they do – without complaints or many demands. And, celebrate the fact that we live in a country where we can.
