BonideSucker Punch, 16 oz Ready-to-Use Spray, Control Unwanted Plant Sprouts, Plant Growth Regulator for Home Garden

I love Aspen trees but the grow new starts from the roots. I found this product is VERY effective in stopping the new starts. I just snip the new growth to expose thr main stem, put a drop of this on the cut and the growth disappears and does not come back. My lawn looks much better without the quick growing sucker's coming up. Takes a couple of weeks to catch them all but this product does a great job!

This stuff works great.

My front year is about 1K square feet. There is 1 very mature oak tree. We never had root suckers until we had the tree pruned extensively before hurricane season last year. Dozens of suckers have sprouted in the year since then. (Maybe the tree was traumatized). I have used 4 bottles of Sucker Punch to try and contain them. With that said, SP does kill them. My grass is the kind that grows out horizontally......... not vertically like St. Augustine grass, so I can wait until the suckers break through the ground, grow tall enough, then spray as many as I can at the same time. THEN I mow.Cons: 1. Agree with others that the sprayer does not work well. When it gets to the bottom, I add a bit of water to thin it out, so I can use every last expen$ive drop.Cons: 2 An expensive way to treat the lawn, because suckers are like gray hairs: pull one and a dozen more grow in it's place! But, since the sucker leaves have sharp edges and stems, keeping them trimmed is better for the kids playing on (in) the grass. I guess "it's not nice to fool mother nature."

I used to have two mature Callery pear trees (Pyrus calleryana), a deciduous tree native to China and Vietnam. They were planted by the home’s previous owner. While they certainly provided shade for home and lawn, not to mention a beautiful fiery display in the autumn (and a foul dead fish odor in the spring), they had to go. These trees are fragile and break, and destroy native plants nearby. They spread like weeds!One bright, hot day in September 2023, the tree in the backyard dropped three branches on the roof. Thankfully no one was hurt, and the damage was minimal. They had to go! A tree service chopped them down two days later. Fast forward to 2025, I needed something to kill the suckers still sprouting up from leftover roots in the soil. Sucker Punch does what the manufacturer says it does. With a bottle in hand, I continue my endless war with unwanted Callery suckers poking up through the soil. As the Bradford is a cultivar of the Callery, it, too, will whither and die from an application of Sucker Punch. The surrounding grass is fine.

The contents of the bottle seem to work fine at sealing the wounds on the tree where suckers were cut off. This prevents new suckers from growing in their place. The problem (other than it being stupid expensive) is that the sprayer shoots out a stream of goop. There are two settings on the sprayer, one for a stream, one for a mist. Both settings produce a stream. So, I had to go find an old paint brush to spread the goop around once I sprayed it. It seems pointless to even offer it in a spray bottle if you have to spread it with a brush. Just offer it in a can (for less money) with instructions to spread it with a paint brush. They do offer it that way, but in a much larger quantity for an even stupider amount of money.Will probably try a different product next time.

If you have a problem with unwanted suckers, popping up from nearby trees, or rose bushes, I highly recommend sucker punch.It really works well and does not harm the mother plant that the suckers are coming from

This is the best product for sucker growth on my trees. The spray bottle is the best application method as I have found out the hard way. However, this product was packaged with flour for baking and did not understand this decision from my perspective as toxic with food?????

Product is effective however the spray is a stream and covers a minimal area.
