It’s that time of year when we all want to get outside for barbecues with friends, afternoons on the patio, and time well spent in our gardens. Our urban forest canopy provides us with shade – much needed respite from the hot sun – but it’s important to remember that trees need some extra care from us during these dry summer months. Here’s how you can help you LEAF trees stay cool this season:

 

Top Five Things You Can Do

 

1. Give your tree a drink. Both newly planted and mature trees need regular watering. Each week, feel the soil near the base of your tree. If dry, give it a long, slow soak. Soaker hoses are great, but a regular hose on a slow drip works perfectly for the trees and shrubs in my backyard!


Superstar tip: ask the person behind the counter of your local coffee shop, convenience store or restaurant to water the tree in front of their business.  Street trees can often be the most neglected part of our urban forest and even a bucket of water can go a long way.

2. Remember the mulch (woodchips, leaves, compost).  This is a tree’s best friend. It holds moisture, provides nutrients, prevents soil compaction, and creates a protective space around your tree. Spread mulch three inches deep around the base of your tree, ensuring it is not touching the trunk (as this can cause decay).

3. Protect your leafy friends. Avoid digging near trees or compacting soil which can cause root damage. Ninety per cent of a tree's roots are located in the top two feet of soil and can extend up to three times the width of the canopy. Be careful when you (or your neighbours) are mowing the lawn – even a little ding in the trunk can cause serious problems.  You might want to also use organic alternatives to fertilizers and pesticides and if you use stakes, remove them after one year.

 

4. Prune properly or leave it to the experts.  Hire a certified arborist and investigate their reputation by speaking with previous clients, or getting a second opinion.
