After reading about the "ram horns" tree in the residential section it made me think. We are the only company in our area that is sealing wounds (as far as I know). Are we doing the right thing, or just waisting our money?

You are doing both, the wrong thing and wasting money.
In fact, scientific studies have shown that it worse for the trees. A nice flat smooth cut is required leaving the branch collar in tact or cutting to the correct angle of a co-dominant stem.

Wasting your money and harming the trees slightly if you are using asphalt based sealers.

Isn't that "wasting - yes" unless your area is thick with oaks and dependent on where you live?
We don't seal here, but I recall that there is an exception, maybe two.

we use sealants in MN only on Oaks during spring months. Avoiding working on oaks at this time is best, but sometimes you have no choice, then only then would we use a sealant.

We sometimes on certain species use whitewash to prevent sunburn. It is painted on the exposed limbs etc of Avacado trees in orchards after heavy pruning. Some trees may get sunburn but that doesn't mean you have to wound dress.

Ekka, Lime (calcium) based whitewash? If so it may have some mild insect repellent properties also I'm told. Certainly has the advantage of providing better gas and humidity exchange than latex.
And yes, there is the Oak death epidemic exception regarding sealant. :angel:

Eric, Not exactly. This isn't about a search for an effective wound treatment. It is about using that nasty black goo that somebody a Chevron conceived as the most profitable way to sell asphalt. Research shows that IT doesn't help as much as it hurts. I believe that there are materials that could prove beneficial. I doubt that there are any that are going to help enough to justify the time and trouble (read expense) of application except for special circumstances. :angel:
