[CANUFNET] Sourcing Nursery Stock

Mon Mar 7 22:58:06 EST 2016

Hello,
Planning bare root trees in Quebec as gotten scarce, fewer nurseries offer adapted species for our ever changing northern Nordic area. B&B, wire baskets are the norm for municipalities street trees and parks. Some 30mm DHP CT potted trees are available with sufficient root systems but in small batches making the use of w-b very costly.  Street trees get severely damaged with snow removal no matter the size, most sidewalks are just so narrow, it's either damage to expensive sidewalks snowcats or trees no matter the DHP. So when looking for nursery stock for urban planting, let's keep in mind installation of winter protection, it's as important as tree selection.

Hello Crispin,

The City of Saskatoon tree nursery does grow a few species from seed. At present we are focusing on American elm, bur oak, and Ohio buckeye which all grow easily here. We hope that eventually we will not need to rely on other nurseries to supply these specific trees. Growing from seed is the only propagation method we use at this time.

The majority of our trees are purchased by tender sent out to nurseries within the prairie provinces and B.C. The tender usually includes 800 - 900 bareroot and 200+ containers. The bareroot and some containers are planted to nursery rows. In-house staff plant the majority of the container trees directly to boulevards.

We do not usually tag or pre-inspect the trees. We do expect the trees to be clean, free of insects and disease and meet the Canadian Nursery Standards. Plant material is thoroughly inspected upon arrival.

Trees are grown in the nursery for an average of 3 -5 yrs (7 – 10 if produced from our own seed). We harvest on average, 600 to 800 B&B trees each year to be planted out by contract. In the past, we have tendered for extra B&B trees when there were planting projects that required more trees than our nursery had available.

Having a civic tree nursery gives us the benefits of having species of our choice, pruned specifically to be strong, well-structured trees for our parks and boulevards.

In the near future we may be able to order more bareroot and less container trees. Last year we started a trial ‘Missouri Gravel Bed’. The idea is that bareroot trees can grow fantastic roots in just a few months in the irrigated gravel and the trees can be easily planted out to boulevards in mid-summer, with less issues and less cost than container trees. I believe we are the most northerly city to try this and so far the results are very positive.

Subject: [CANUFNET] Sourcing Nursery Stock

Hello All,

I am interested in knowing what processes and/or practices municipalities across Canada use to source and procure quality, caliper nursery stock to be used for street/park plantings? I am particularly interested in whether your organization produces its own caliper trees? If not, do you physically select or tag trees at the nursery prior to purchase? If you do, how far do you travel to do so?  and lastly, what criteria or specifications do you use to define a 'quality' nursery tree?

Any feedback would be appreciated.
