How to Band Your Tree

- Russell Eirich, Acting Manager - Forestry, Horticulture and Pest Control demonstrates tree banding techniques that residents can use to protect their trees from cankerworms this season.
The City of Regina encourages residents to start banding all of their elm, fruit, or Manitoba Maple trees in the spring (late March to mid-May) and fall (September to mid-November) to trap female cankerworms as they crawl up the trunk to lay their eggs.
The City is planning to band 400 trees for monitoring and control. The information will be used to determine cankerworm infestations in the city and where spraying for cankerworms should be focussed.You can hire a company to do the work or band the trees yourself.

What kind of grease. It will run down onto tree, will it hurt the tree. I used lard last year on bare trunks of Linden and, it did not help. Lard after lots of rain ran down the tree.
at 13 seconds into the video it lists all the supplies you will need. Axle grease, tanglefoot or stick-em are all listed
Instead of insulation I used foam strips from old dismantled couch cushions. It is the same thickness as insulation & seemed to work fine.
I've seen craft polyester fill used too instead of insulation. Maybe Walmart or Michael or fabric land, I'm on the hunt today
does that work for silkworms
No, this doesn't work for Silkworms. It is for Cankerworms, as they have a wingless female. The bands are only effective during the egg laying stage of the insect, not the larval stage.
Pines don't require banding, am I right?
Correct, not pines. Band elms, Manitoba Maples and fruit trees only.
Can you purchase the rolls of plastic as depicted in the clip?
Yes, it is pallet packing wrap. Or you can also cut a garbage bag up to make the wrap.
At staples, large roll approx $12.00
My tree is old and large and the bark is very rough. It has deep grooves-like areas where more than one trunk is fused together. How do I fill those gaps?
The insulation should be thick enough. When you tighten the plastic around the tree, that will compress the insulation into the tree grooves.
@@cityofregina If I wrap the insulation with the plastic there will be gaps that the tape won't have contact with the tree and the insulation will be exposed. The insulation will get wet when it rains. Will this hurt the tree? It's a huge old maple tree and the alcoves in the trunk are quite deep. It was inundated by the caterpillars last year.
The band won't be on long enough to be of concern as it is to be removed by mid-May.
@@cityofregina I'm in Massachusetts. We have had a very cool wet spring up to now (mid May). There aren't signs of any caterpillars as yet. I haven't wrapped my tree because it has just leafed out. Are different areas earlier with the infestation? Also, perhaps you misunderstood my question. Wrapping the tree will be difficult because of the shape of the trunk. There are large, deep gaps that run the length of the trunk because it's like four trunks fused together. The tree is quite old and very large. Won't the caterpillars just climb beneath the "bridge" created by the insulation not filling the deep grooves but passing from one trunk "section" to the next? For example, if I sawed the tree the stump would be shaped like a four leaf clover not a circle. I'm hoping our wet spring killed off the caterpillars this year. Sorry for long comment. I will try stapling it into the grooves. I will probably need really thick insulation and heavy duty plastic...a challenge for sure.
The bands are to interrupt the egg laying cycle of the cankerworms. This is because the female is wingless and has to crawl up the tree. Once in fall (fall cankerworm) and once in spring (spring cankerworm). Regina is a lot colder than Massachusetts, so our springs are later and falls earlier. Usually the females are doing their egg laying within about 3 weeks of spring melt and winter freeze up. So all in all we think you’ve missed your chance this year. Try again in the fall.
As for your problem the way you described - we would suggest making one large band. But then fill in the gaps with extra insulation so nothing can crawl underneath. Barring that, put the band up higher when the trunks begin to separate. But that may be too high for practicality or the females may lay their eggs below the band.
Make sure you take the bands down in the summer to ensure the bark has time to dry out, too.
Good luck.
