Who leaves synthetic twine on trees ???

Actually, I'm surprised that nurseries even use synthetic twine anymore. But how often does any "landscaper" leave synthetic twine on trees after planting? Or ... say even the other natural fiber that will decompose?

Just added this, too, on my new website blog.

Recently, I was hired for consultation, and immediately after, asked to inspect 400 trees planted in the past couple of years. Mostly to prep for bark mulch that I recommended, and to start checking the lower trunks, because twine was left on most of the trees, ranging from 6' Grand Fir and Incense Cedar, up to 10' Incense Cedar.

Next week, about 15 "units" of hemlock bark will be blown, providing approximately a 6 ft. wide circle or mulch, about 3 inches deep, for each tree. About 12,000 square feet combined, worth of hemlock barkdust.

Actually, even the trunks with the natural twine fiber had indentations on the lower trunks, because several wraps still hindered one or two season's worth of growth / expansion before the material started to fall apart. And on some, had not quite decayed yet.

A new one for me to find there, was not that trees had been grown with root containment bags ... but that they had been planted in root containment bags. I first experienced seeing these bags in southern Oregon, and never liked them from day one, even if they can be removed.

It was interesting to give an estimate for, because of the sheer number, and I had to ballpark guess how many minutes it would take on some trees to prune a few low limbs for visual access and working room.

So it was trying to figure is this 2 minutes per tree, 3 minutes, 4 minutes, etc..

I've based hundreds of estimates guessing in 1/4 hours or a tally of total hours ... even 1/2 days or full days. But this was the first I recall basing the math on multiplied by a few minutes or whatever.

We do alot of planting at the forest preserve and my my company. We will remove top half of the burlap and all twin and if it has a wiire basket. If the tree has a large canopy and will be like a sail, we will put on guide wires.

Nurseries around here tend to use synthetic twin to sew the burlap tight. If I need to keep the ball in the hole as complete unit due to a lose ball from moving it around to much. That I will just remove the syntheic twin and come back the following year to remove or check if the twin has broke down. Some people dont agree with keeping any thing on the the ball but this has worked for me over the years.

On the grow bags, we use them alot on reforestation projects at the forest preserve. We get mostly oaks. They are 1-1.5" in size. The bags create a very fiberous root system. The bags must come of when planting. The bag is treated so when the roots hit the bag it will burn the tip and encourage more roots.

I have never seen anything planted like that! I am guessing that the bags should have been removed. Taking 2 minutes to cut the twine off the base is time well spent. I have sometimes been forced to leave the basket on (homeowner reads somewhere that you should) but remove as much as of everything as you can.

So how did you end up estimating your time?

There is diffrent style of bags that have come out over the years. Some are thicker material. The thing that nurseries have to watch for and we have had some problems with, the tree has become to large and has not been transfered into a larger bag. The roots will start to grow into the material and that becomes very hard to cut off from the root system.

With the basket, we will get the tree in the hole and then cut the top half off if the ball has not broken apart.

I have seen trees slightly girdled like in that pic but what long term affects will it have since it was not actually grown in?

That's where I told the homeowner 50/50 chances on a few of the worst ones.

It should depend on whether it destroyed the cambium or phloem there or not. If the cambium was destroyed, then it really can't make any more phloem. And the cambium may be only like 1, 2 or 3 plant cells in thickness anyway.

Bark blowers came in today.
