twine around my black hills spruce and meyer spruce transplants #867270

Asked May 06, 2024, 2:46 PM EDT

Hello - I have a couple questions about some trees that were transplanted in 2021. We had 6 trees transplanted: 3 Black Hills Spruce (8-9 fee tall) and 3 Meyer Spruce (7-8 feet tall). They came with burlap on the roots and I believe were planted with it on them. As the trees have grown over the past 3 years, the part of the tree with twine around the trunk has come up above the ground. As you can see in the pics, the trunk is not able to grow where the twine is so it looks constrained. So my questions are: - Should I cut the twine off where I can see it? If so, should I dig down on any of them to find more twine? I'm going to try not to, but is there an issue if I cut the tree when trying to remove the twine? - Is this a concern for the health of my trees? - Is there anything else I should do to the trees to ensure good tree health? - The trees appear to be doing alright/good, but there are a couple bare spots and small brown areas on the bottom of a couple of them. Could the twine be contributing to that, or is that most likely from the drought or not getting enough water? Thanks, Tony

From the photos, that twine is killing your trees. 

First off, I would call the company that planted them and ask that they come out and replant them. 

If they were ball and burlap, that should all have been removed before planting. Page10 on the tree owners manual below explains this. 

The dug, these trees likely has severe root pruning before being lifted from their site. The wire and burlap, over time, constrict the roots and can choke off the tree. They can also cause stem girdling roots which encircle the tree and choke it off. 

If the company that planted them won’t help you, for sure, cut the wires and remove the twine. Try not to damage the tree but they should recover from a small nick. Trees are good at sealing off wounds. 

Removal of the container material will help to ensure your trees remain healthy for years to come.
