Sink or Source is a term used in arboriculture to describe how a branch responds in regards to how it provides or uses up sugars within the tree. When a branch is using up more than it produces, the tree will compartmentalize the branch at the union point at the main meristem. This is why when you look up the tree you will see that most of the lower branches are dead or declining because of inadequate sunlight filtration. Removal of these branches lets the sun and air through the tree and helps to invigorate the remaining foliage as well serving to protect what is under the tree from falling branches.

Here at Jacob’s Ladder Tree Tech, we use non-invasive climbing and rigging techniques when the tree is not a removal. This means the use of friction savers and blocks to protect the cambium layer of the tree. Cambium is the layer under the outer Bark that is responsible for tree growth and production. We use static rope climbing techniques instead of spurs or spikes that dig into the cambium and create potential entry wounds for disease.

Jacob’s Ladder Tree Tech is wonderful. He knows his work and it shows in his explanation of what he does. He is not pushy and very reasonably priced. Definitely recommend. 👍👍👍👍

I started a small property management company and was looking for a small business to handle the lawn maintenance at my rental houses. The large companies are ok, but there's no personal service and the tech may change from week to week. I needed someone I could trust to not only do a good job, but who would also report back to me with any maintenance issues or concerns. Thankfully I found Jacob!! He is friendly and personable and a very hard worker! The yards he's maintaining are newer sod and between the irrigation issues and the super-hot weather, it's been touch and go all summer. Jacob texts me updates and reports any problems he sees every week when he mows. He's so great, we hired him to handle our own house! Plus he knows his trees!

(Sept 2021) We called Jacob's crew back to remove a large dead Locust tree looming over recently planted landscaping bushes, and they were able to pluck the tree away without any damage to the bushes below. They also removed a large dead Poplar tree looming over a property fence line, again with care and no damage. And after ~20 years of personally not keeping up with pruning a large Magnolia tree, Jacob's arborist Eric (pictured) did an amazing job pruning the Magnolia back to size and shape.FYI - as of Fall 2021, Jacob has started a second operation in Idaho, so some Google details may show Oregon or Idaho, but both are valid.(Feb 2019) Awesome and professional. A snow storm fell a large cedar tree across our house power line. Pacific Power took care of the line itself, and Jacob was very quick to respond with an onsite assessment and quote, and wedge the job into his busy schedule. Everything was clearly explained, and he and his co-worker were very professional and properly equipped while on-site. Invoicing by e-mail and payment online made it easy to close things out.

2021. I had Jacob and his team fell 3 hazardous trees, clear away a fallen tree, and top my hedge so I could reach the new growth to keep it trimmed myself. Eric and his team were courteous and did their work with quality and integrity. They had me check their work as they progressed to ensure that I was satisfied. This company is the only company I call for my tree services--THEY ARE FANTASTIC--and their prices are reasonable! :). I highly recommend their services.2020 TERRIFIC! HIGHLY RECOMMENDED! Can't say enough great things about this company! The owner and employees were exceptionally respectful, worked diligently and responsibly, and their prices were reasonable. All my future tree trimming/cutting will be done by this excellent company.

We had a half dead birch tree in our backyard that I have been wanting to remove for a while. It split into two right at the base of the trunk and with the one side dead and our two year old, of course my concern was that eventually it would fall. Jacob was able to come and give me a estimate within just a couple days. Of course this is dangerous work and I'm sure the insurance is astronomical, you can't expect work like this to come cheap. Knowing that however the price was not unreasonable. He even supports military/veterans with a bit of a discount which is greatly appreciated. Not too worried about the timeframe he was still able to get us in a whole month sooner than expected which was a nice surprise. Him and his crew we're on time and had the whole tree plus a couple little stumps from some smaller trees that I had removed in 4 hours flat. They were exceptionally careful with anything we had in the yard and cleaned up very well after the job was finished. I couldn't be happier. I'm a firm believer that you get what you pay for and received exactly what I expected. Plus some. This might not be important to all but I do have a two year old who is a sponge with information and vocabulary. I didn't hear any profanity while they were working. I appreciate that. Thank you again!

Jacob's Ladder Tree Service did an outstanding job from beginning to end. The crew was very professional and polite. Our trees look so much better now and our ugly dead tree in the back yard is now gone. Thanks Logan. It was fun watching you top the tree. I would highly recommend their service.
