Field sales call survival

By | Arborist Insights, Pruning | No Comments

Spring. It’s a time of renewal and, as the Tri-City News reminded me recently, it also brings out salesmen. But don’t worry, you don’t have to let them in. And you have thirty days to change your mind if your purchase is over $50. Good to know.

I was thinking about this after I had a salesman visit me in the field. The guy simply drove by my work site and saw my piles of branches. My goal for the day was to thin out Robinia pseudoacacias. So he stopped and searched out the sweaty arborist. Normally, I brush salesmen off but in this case, I was very happy to talk to him. As it turned out, he had lots of ‘toys’ in his truck.

Arborist ‘toys’

Doug pulled out a telescoping pole saw which was awesome. It’s a bit heavy but the telescoping is nice. The hand saws had me drooling. I especially liked the hand saws that attach to your leg for easy access. One day, when budget allows, I will invest in one.

Right now I am happy with my Samurai hand saw I purchased in Japan for about $35. Always get good quality steel. Having a nice, sharp saw is critical. I still remember a seminar I took at the UBC botanical garden years ago. They had an arborist doing a demonstration in a tree and his hand saw was gorgeous. Light reflected off the saw and it made a beautiful sound when it cut through the wood. I wanted one like that ever since.

Later on, the same arborist pointed out that his hard hat is worn to separate himself from landscapers. Aha! I was insulted and too shy to interrupt the demonstration. Hard hats are for safety. There are many professionals like me who are both ISA certified arborists and landscapers. Skilled, total professionals. My focus is on good quality work, not on separating myself from anybody. Remember, be so good so they can’t ignore you!

Sales details

I am very happy to plug a green salesman in a blog post. Always help others succeed. Unfortunately, many companies have go-to dealers so it’s up to the salesman to spin his magic and develop new relationships. Saws get dull and abused. You will need new ones.

Doug Cox of Calmac Saw & Supply can be reached at 604-816-6915 or calmacsaw@gmail.com. Please tell him you found him through this blog. Perhaps he can demonstrate his saws for you.

Katsura tree with too many leaves

By | Arborist Insights, Pruning, Trees | No Comments

“Every year this tree makes too many leaves.” That is a direct quote from the strata owner whose patio looked out on a nice Katsura tree specimen (Cercidiphyllum japonicum). I almost laughed. The tree makes too many leaves every year? Really? I talked to her politely and agreed that some thinning cuts were in order. But too many leaves? That deserved a blog post.

Thinning cuts

On a multi-stemmed tree like this one, thinning cuts are totally fine. Just pick a branch that rubs or crosses with others and remove it. You should be able to create some openings in the crown while still preserving a natural tree look. I didn’t have any trouble with this. It was easy to see crowded spots.

Just remember not to go too crazy. You can always come back next year. I made a few cuts on every tree and assessed it before taking more. And I will assess it again once the trees leaf out.

Too many leaves

This is a joke. Trees know what to do. We can’t tell them how many leaves to produce. What’s the big deal with leaves?

Trees use leaves as factories to make food from sunlight through photosynthesis. This is a free service which produces oxygen for us and removes carbon dioxide from the air. This process also releases water which affects local climate. Without leaves the tree can’t survive.

Once the food is made it is distributed throughout the tree. Upper branches can act as storage sites which is why pruning during drought can starve a tree. Under drought conditions, leaf openings called stomata close to prevent moisture loss. This, in turn, means that carbon dioxide can’t enter therefore food production stops. Then, here comes a landscaper with strata orders to prune trees. As he removes some of the upper branches, he removes food that was stored in them. Boom. Starvation ensues.

Leaves also serve as food for various animals and they act as cover for birds. For example, caterpillars munch on young leaves and are in turn eaten by birds.

Leaves also look great in the fall as they turn color. This katsura tree is no exception.

Too many leaves? Not likely. Let the tree do its thing.
