Every time I have used this, the weeds have come right back within a couple weeks.

Hello Tyler! Thank you for sharing your experience. If the treated plant fully died, it would not come back to life; the growth you are seeing may be new weeds or regrowth from roots that were not fully affected. Spruce is not a preventative herbicide, so reapplication may be needed. Apply it thoroughly to all green leaves and stems for best results. For additional questions, contact us at (888) 398-6055.

Finally something pet-safe that actually kills goat heads!
Living out here in West Texas, goat heads can be painful for dog paws. This spray worked great at knocking them down and clearing out the yard. Most importantly, it gives me complete peace of mind knowing it's safe to use around my pups. The refill size is super convenient to pour right into a reusable sprayer.

this is the best weed killer, I have found. it works great. I like the refillable bottles. I previously purchased the bottle with the sprayer attachment. It was easy to use and attach to the sprayer.

It works with frequent use
This stuff does the trick but the weeds come back much faster than other unsafe brands. We have a sweet labradoodle though and I don’t want to risk spraying something else that she might ingest and get sick. I do have to use this with more frequency than I would other products and it’s more pricey. It’s worth the peace of mind.

Hi there! We are truly pleased to hear that Spruce Weed and Grass Killer does the trick for you, especially given your concern for your beloved labradoodle! It is wonderful to know that our product provides you with such peace of mind. We understand that weeds may return more quickly than with other products; it is important to note that Spruce is not a preventive weed killer. This means that it kills the weeds it contacts but does not prevent new weeds from growing back. Thank you for choosing Spruce for a safer option around your pet!

The scent is pleasant too.
I found this product searching for something safe and non chemical. I ordered it immediately, used it the same day I received it, saw results the next day and ordered a refill. It’s great, thank you!

If you have full or tall weeds, expect to have to spray more than once
This product does a good job killing the weeds above the ground, but the roots are still there & active. I sprayed the worst weeds maybe a week ago, the part above the ground is dead & in a compost bag. Yesterday I noticed some of the "dead" weeds starting to grow again. I resprayed again this morning spraying the ground where the new growth was coming in & spraying any exposed roots.

Hello! Thank you for sharing your experience with Spruce. Spruce works by killing only the green parts of the plant that are in contact with the spray, dehydrating them down to the root. By thoroughly spraying the entire green parts, the roots will eventually die. For larger or more established weeds, multiple applications may be necessary to achieve full control. If you have any questions or need further assistance, please contact us at (888) 398-6055. We’re here to help!

Works very well!
10/10 would recommend. Picked this up on clearance over the winter. Just used it this Spring. In about a day it melted away all the weeds that got sprayed. Smells minty. I only found the refill at the time, so I used it in a pump sprayer and diluted with about a 1/3 part water and it was still very strong. I would definitely buy it again.

It does get about 70% of your weeds. So usually a couple days later I will have to make a second pass. I do wish it was slightly cheaper due to the fact I have to use it a second time.

Effective for everyday weed control, but tougher w
[This review was collected as part of a promotion.] I liked this product overall and found it easy to use, especially for routine weed control and general lawn maintenance. It worked well on smaller, newer weeds and helped keep things from spreading. That said, it didn’t fully eliminate some of the more stubborn, deep-rooted weeds even after multiple applications. I appreciate the refill size and the more eco-conscious approach, and I’d still use it as part of regular upkeep, just not as a one-and-done solution for tougher weeds.
