Spruce is a fast-acting weed and grass killer that's safe for use around people and pets when used as directed. Spruce is a contact herbicide, so it kills the plant where it contacts it (or is sprayed on). For best results, maximize the contact with weeds by spraying the entire plant - including all the leaves. Spruce kills weeds and grasses in driveways, patios, mulch beds, etc. We don't recommend using it in lawns, as it will kill grass that it contacts.

Spruce is different because it is designed from the start to be easy to use and to be safe for use around people and pets when used as directed. Spruce contains essential oils and surfactant to start working fast, and you can see all 9 simple ingredients on the label. We designed our sprayers and wands to be easy to use, we even offer Power Wand and EZ-AIM versions of Spruce for people who want a continuous spray with just a single trigger activation.

  • Tip #1) The easiest way to stop weeds is to catch them when they are small!

    Weeds can ruin the look of your outdoor spaces or even break up your landscaping. While some may feel overwhelmed by the persistent presence, there's a simple yet effective strategy to manage them - don't wait, kill then the first time you see them. The adage “a stitch in time saves nine” holds true in with weeds; Kill weeds while they are still small, before they can establish their defenses or reproduce.

    Don't wait until weeds are full grown, it only gets harder to treat. Just one weed can lead to a population explosion

    Have you ever seen one weed, only to be astounded a few weeks later when your yard is taken over by them? Most weeds germinate in just a few weeks. Letting just a few weeds stay could spread them all over your yard, and your neighbor's yard. For example, the dandelion has roughly 200 seeds per flower and 10 flowers per plant, what could be 2000 baby dandelions each time one reproduces. Some invasive weeds like the Palmer Amaranth have over 1 Million seeds per plant. If you want to stay ahead of the game, catch each plant early before it reproduces.

    Large weeds can break up your landscaping

    Weed roots commonly break up concrete, blacktop, rock beds, and pavers - and can cause hundreds of dollars in damage. The roots act like wedges in between small cracks, slowly pushing them apart. Weeds use the force pushing your concrete apart to stabilize their growth above the ground. Weeds can be even more detrimental if you live in a cold climate, where the weed roots can hold water that freezes and further cracks your walkway or driveway. Some of the common weeds with destructive roots -

    • Dandelions (scientifically known as Taraxacum officinale) are known for their strong taproots. The taproot is often longer than the plant is tall. When taproots are prying their way into a crack, they can force small cracks open to become big cracks. Dandelions are also known to be one of the first weeds to emerge in the spring, so be on the look out to treat them eary.
    • Broadleaf Plantain roots are known for finding the smallest cracks, then their fibrous roots spread out and can cause damage by holding water in between pavers and cracks. (Note: While the name broadleaf plantain sounds like it would be a cousin of the banana - it isn't. Broadleaf Plantain is the weed you likely found on the playground as a kid or in the sidewalk around your house, as it is found almost everywhere in the US.)

    Small weeds are easier to kill, preventing regrowth in the future

    When weeds are small, you have a much better chance of killing the entire plant and preventing it from coming back. Once weeds are full grown, they have developed all their evolutionary tricks and are more difficult to eliminate. Some of the evolutionary tricks include:

    • Thicker Cuticles: Maturing weeds typically develop thicker protective layers, or cuticles, which can make it harder for herbicides to reach the growing parts of the plant. The cuticle is a waxy layer over leaves and stems that acts as waterproofing, making it more difficult for herbicides to soak in. Spruce is designed with an ingredient that helps it breakthrough cuticles.
    • Woody Stalks: as the weed grows older, they can produce woody stalks. These stalks are made of dead cells, so they protect younger growing cells inside from physical damage or herbicides. Not much gets through woody stalks. So once weeds have woody stalks, physically pulling the weed out is often the best choice.
    • Increased Root Depth: Mature weeds often grow larger and develop deeper root systems, allowing them to access more water and nutrients. This makes the weed more difficult to pull out and more resilient treatments.

    Remember - the sooner you address weeds, the less effort you'll need in the long run to keep your outdoor spaces looking great.

  • Tip #2) Killing weeds is easier on warm days

    Weeds are very sensitive to temperature. Weeds go dormant or enter a period of inactivity during the winter. This dormancy allows them to survive harsh conditions, cold temperatures, and limited sunlight. During dormancy, weeds shut down most of their cell activity and are difficult to kill. When the weather warms up, the cells in weeds kick into high gear to start respiration, photosynthesis, and transpiration - all the processes needed to grow as fast as they can. All these cell processes need water in the cells to allow their function, and they need even more water on warm days. Spruce Weed and Grass Killer2 dehydrates the cells until the plant dies. So, the warmer the day, the quicker you will see the visible effects of Spruce. This is also why we recommend using Spruce on days where the temperature is 60 degrees or more, as you will see the best results.

  • Tip #3) Read and follow the product label before use.

    Different weed killers can have very different instructions and uses. The label instructions are designed to give you the best results and the proper handling. So it is worth the investment to read the label to make sure you are getting the most out of any herbicide.

  • Dandelions scientifically known as Taraxacum officinale, are ubiquitous flowering plants commonly found in gardens, fields, and lawns across the globe.
