the plastic is caliper limited.. eventually your tree will outgrow them ... but in the mean time.. they can be reused year after year until then ... and in fact.... can be just left on the tree ....

i dont know how long the wrap works ...

what caliper are your trees?

I like the white plastic wraps - protect against deer as well so I put them up early fall.

I use them on up to 6" caliper trees - you just need more of them

i left the plastic ones on a couple crabs.. for a decade ... lol ... when i finally got around to removing them.. they were so brittle.. they just cracked off ...

the beauty of it.. was they just kept expanding ... never doing any harm ...

The caliper is about 1.75"-2" approximately.

Any concern with the fabric wrap holding moisture against the trunk all winter long? Regardless, I'll probably go with the vinyl.

I use and trust the corrugated plastic and this other flat wrap-around type:

I am skeptical of the fabric wraps but I am also in a colder hardiness zone than you. A person does have to be careful when putting the corrugated tubes on so you don't scrape up trunk some. The plastic edges can be a little sharp on young maple bark.
