Can this be used on rose bushes

Asked by Mark March 14, 2021

It says small shrubs so I would use it. I would make sure you only spray the end and not the rest of the stem/branch.

Asked by KenO December 12, 2020

Scotes outdoor cleaner plus oxiclean is my pick. There are others but seem to harsh. As always try a small spot to make sure it doesn't have a negative effect.

Is this stuff the same as Flex Seal?

Asked by Stewie September 3, 2020

No. The SDS (MSDS) for Spectracide Pruning Seal is available on the homedepot.com product page for this spray sealant (basically, it appears to be an asphalt compound with a mineral spirits carrier and some Xylene quick-drying agent). Flex Seal, on the other hand, is a liquid rubber of some kind, with toluene and some aliphatic petroleum distillates, etc. (SDS is at https://sdsinventory.com/substances/accessSDS/SDS-101102-581b5448a15476.26351891 ). I wouldn't say that Flex Seal is necessarily a suitable material for sealing cuts or wounds on trees. Being 'rubber' it would also tend to trap moisture underneath for a Long time and that might not be good for the tree.

is there extension pole to spray Pruning Seal in high areas of trees after pruning

Asked by Sonny August 8, 2020

Homedepot.com sells an accessory that attaches to an extension pole (search for 314616562 ) This device snaps onto the round collar at the top of the spray can... but it will only fit certain size cans; some reviewers say it won't work with all brands of wasp & hornet spray, for instance. There are other similar devices on the market which utilize an adjustable band clamp to hold the can; search for "Aerosol Spray Can Extension Pole Adapter"

Can this be used when pruning rose bushes?

Asked by BW July 27, 2020

Yes. That’s what I bought it for.

Asked by Tony July 19, 2020

There are several other good products that will better serve you for the pressure treated lumber use. I would do more research before using this product.

Will this product stop the cut limb from going again?

Asked by Johnmatt July 5, 2020

If the tree is a type that tends to grow new 'sprouts' around the cut-off limb ... this pruning seal will not typically prevent that. So, it will be necessary to cut those regrowth twigs off each Fall or winter to stop them from turning into new branches. However, it is VERY important -- when removing a limb -- to avoid cutting off or into the 'Branch Collar' so the wound will heal faster and properly. https://www.thedailygarden.us/garden-word-of-the-day/branch-collar

Container failed & tar got everywhere
Had stored on a shelf in my garage in TX. Container failed and it leaked a bunch of tar. It dripped down and got on some stuff including my extension cord, which I used without realizing, so that got tar on my carpet and also on my favorite pair of pants. So yeah, I’m understandably disappointed with this product.

Been using this product for years. This purchase was to replace used product. We have to deal with two feral cat colonies using trees as scratch posts, and severe winter killed trees.

Does the Job but
This Pruning Seal does the job but as another review stated it's kind of thick. Sealers I've used in the past have been more like spray paint. This product has the consistency of a thin glue. It did the job but I would advise you wear gloves and have on old clothing.

It is a great product, I just wish it was clear not black it really shows up on my green hedges. If it was clear you wouldn't see it. and it would still protect. It worked like it said it would.
