Bonide (BND221) - Aerosol Tree Pruning Sealer, Protective Wound Pruner Seal for Shrub, Tree, or Rose (14 oz.)

I do a lot of garden work. Ordinarily I do not use pruning sealer. The thinking behind this is most tree and shrub wounds will heal themselves and often artificial sealing will create a situation where you're actually sealing IN problems, like mold and insects, etc.We had a horrific storm here in CT and lost many trees. And those we didn't lose, lost major limbs. We had to have tree people come here and radically cut away large limbs, clean up torn bark, etc. In the case of one very old and large japanese maple, we lost 1/2 of it's largest branches. So it's a tall, thin tree, instead of a great wide lush tree. Very scary.The tree guy said seal the bark which is torn. Don't completely seal it up because you can't but try to help the tree through the winter.So we bought a lot of this Bonide sealer, for that tree and an even larger oak. It seems to have helped. We won't know until the spring or summer. But the sealer looks good and the tree is strong so far.What I do know about Bonide is this: I've used it before, it's excellent as a sealer and stays on once it dries. It is also very good for sealing the insides of wooden window boxes and clay pots. It's like spray tar.I would suggest buying a clip on sprayer, to help with the spray because depressing the spray nozzle after a while is difficult. This is thick stuff. It tends to ..not clog but get messy as you depress it. And then you want to be able to effectively keep shaking the can to get the most out of it without it sputtering and making a mess on your hands and clothing. And it could. But it's worth it because it's effective.The seller is the manufacturer. When I asked them to please ship quickly and told them why I was buying so many cans, they shipped overnight. IMO, they're good people and sell a quality product. And the price is about 2/3 to 1/2 what you'll pay in your garden shop.

We removed a number of lower hanging limbs. It was unsightly and we worried it would damage the tree over our hot summer. This spray goes on easily; it’s sticky at first and that took over 24 hours to dry thoroughly. The end result is almost the same color as tree bark. We believe it will really help keep bug attacks on the tree to a minimum.

Product was easy enough to use, however it sometimes accumulated around the spray nozzle, and then then made large drips. If you're gonna use it while on a ladder, lookout below for the person holding the ladder steady!

Had some cracking on my maple tree and this product covered the area with ease.

I was surprised at the adherent of the compound to shrubs limbs. I have always trimmed my crepe myrtles soon as colder weather sets in without any protection on the limbs from fungus, bugs, e.t.c.. As the crepe myrtles ages (10 years now) I felt it might be better us use a compound that seals and protects the cut limbs.After several applications to the cut limbs, I was satisfied that the compound wound protect as advertised

After application the tree actually appears to heal itself. Prevents insects from damaging Rea under the bark

I use this spray whenever I prune the larger branches from my fruit trees. It's much easier to use than the "brush in the can" sealer. I also have 2 very old fruit trees that have had various problems with boring pests, leaving dead wood on branches and the trunks. After I spray and clean the dead bark away, I spray with this pruning sealer to protect the tree.

Bonide (BND221) - Aerosol Tree Pruning Sealer is a fair sealer, Very Thin mixture and Lots of Blow back. Wear disposal gloves when applying because of Blow Back. I used insecticide one day before to kill any insects.
