Protecting Cedars From BC Heat Waves
When we plant new cedars in the spring or summer, very hot weather can be hard on them. In today’s blog article, we are going to talk about what you can do to protect young cedars from BC heat waves.
The first thing to know is that you cannot cover them to protect them from heat. Covering plants makes them warmer and creates a Greenhouse Effect. It would also not be practical to try to cover a big hedge that is several feet tall.
There are really just two things that you can do to protect a cedar hedge from heat: mulch and water.
Mulch is something often overlooked and underappreciated. Mulch performs two important jobs. The first one is to prevent other plants like weeds from taking root at the base of your hedge. Weeds will compete with your hedge for water, and this is particularly bad when it is very hot outside.
The second job that mulch performs is to minimize evaporation of water from the soil. Water is very important for a young, newly planted cedar hedge, not just getting enough of it, but also keeping the water in the soil and not letting it evaporate into the air. Mulch should be at least three to four inches deep, with more added over time as it breaks down.
As mentioned above, water is extremely important for the young cedar hedge. And the hotter the weather, the more important watering is. A hedge should be watered about twice a week very deeply. Watering deeply is more important than watering frequently. The most common reason for new cedar hedges to suffer is lack of water.
If you water your new cedar hedge enough and have mulch in place, then your hedge should do fine, even during our BC heat waves. For new cedar hedging, give us a call on the Lower Mainland at (778) 241-5664. This is our business and area of expertise.
