Roundup ProMax

Free Shipping on All Orders

Roundup Pro MAX is a herbicide that penetrates the leaves and moves to the roots of weeds faster so that in can provide weed control, with virtually no regrowth. When you spray Roundup on a weed, it is absorbed by the plant, where it then prevents the plant from making its own food and gathering nutrients to sustain itself. Roundup is then transported throughout the weed to kill the entire weed, roots and all.

Will this kill weed only? No damage to st. Augustine grass?
Lala on Mar 6, 2017
BEST ANSWER: The Roundup ProMax is a non-selective post-emergent that is used to control a broad selection of weeds. With it being a non-selective herbicide it will cause damage to your St. Augustine grass. You can spot treat the weeds that you are wanting to eliminate and allow the St. Augustine to take over that patch on the lawn.
Will it harm horses or pets?
A shopper on Mar 29, 2018
BEST ANSWER: The label says to let the spray dry for an hour prior to allowing pets on it. Since horses are herbivores I probably wouldn't allow a horse on it until the sprayed area shows visible death.
will roundup kill flowers such as daylilies?
A shopper on May 20, 2018
BEST ANSWER: Yes, the Roundup is what we call a nonselective herbicide and it will kill flowers and grasses.
Will this product kill bamboo ?
Ra D on Apr 2, 2018
BEST ANSWER: Yes, Roundup would definitely kill Bamboo but we recommend apply a fertilizer at the same time, kind of tricks the bamboo. Allow it to completely draw the mixture in and do not cut the bamboo down.

It will take some time, but eventually the plant will fall over and you can simply pull it out.

A shopper on Feb 21, 2018
BEST ANSWER: You can plant in a couple of days after application of the Roundup ProMax Herbicide.
