How to Apply?

When plants are dry, sprinkle these seeds on the soil surface at the rate given below for your specific planting requirements. After activation with watering, it will form a weed control barrier in the top layer of soil up to 1 – 2 inches. This layer can prevent weed seeds from growing. Disturbance to the soil surface after activation can contribute to erratic control of the weed. 

When to Apply?

During the growing season, spray Preen Garden Weed Preventer around existing plants and transplants. On flower seeds, preen should not be used. You can apply it after flowering plants have germinated and reached a height of 2 to 3 inches. Preen may also be added after mulching beds or blended into the soil while seeding vegetables. By applying Preen earliest possible, you can vanish the requirement for hand‑weeding.

Rain does not wash this product out of the soil. To keep beds weed‑free all season long, reapply Preen weed preventer every 9 – 12 weeks.

Applying Around Established and Transplanted Plants

Sprinkle 1 oz per 10 sq ft of Preen Garden Weed Preventer evenly over the entire soil surface for flowers, roses, herbs, ground covers, ornamental grasses, shrubs, trees, and specified vegetables at least 2 – 3 inches tall, making careful to keep granules away from plant roots and foliage. You need to water it immediately. If watering isn’t an option, gently rake the soil surface. To avoid damage or discoloration, often wash or brush off stray weeds preventer granules from plant foliage.

Applying with Mulch

We recommend using Preen Weed Preventer after mulching your flower and shrub beds for the best weed control. Sprinkle Preen on top of the mulch, being sure to keep granules away from plant foliage. Immediately water this product into the mulch. If watering-in is not convenient, lightly rake into the top layer of mulch. Always wash or brush off stray granules from plant foliage to avoid damage or discoloration.

Weedkiller vs. A Weed Preventer

Lots of products help control the bane of gardeners everywhere – weeds. But how well you get the job done depends on whether you’re using the right product for what you’re trying to accomplish.

One trip-up can happen when it comes to buying a weed killer vs. a weed preventer. Weed killers – also known as herbicides – will kill existing weed plants. Some kill broad-leaf weeds in lawns without harming the grass, some kill grasses but not broad-leaf plants, and some kill pretty much anything green. What they don’t do, however, is stop new weeds from coming up.

When bare soil is left behind where a dead weed was growing, weed seeds capitalize on the opening – often within days or after the first rain. That happens because weed seeds are often buried in the soil waiting for sun, rain, and an opening to sprout, or new ones blow in or are carried in on insects and bird feathers. Digging in your soil can also make them surface.

Personal Safety Considerations

It’s likely that Preen Garden Weed Preventer may irritate your eyes or skin. When working with this product, wear eye protection. On a windy day, it would be more difficult to hold the product off your face and body.

Since this substance can cause skin irritation, wear full-coverage clothing and shoes when working with it. To avoid skin and eye irritation or an allergic reaction, wash your hands thoroughly after handling Preen, including the jar itself.

Post-Application Considerations

Examine surrounding areas such as the patio, pavement, or driveway after applying Preen Weed Preventer. Sweep up any leftover granules and put them on the soil that has been cleaned. At least when the watered soil is dry, keep animals and people away from the treated areas. As required, apply the weed preventer every three to four months.

Environment Safety Considerations

You should not use Preen Garden Weed Preventer in ponds, streams, rivers, or storm sewers. This weedicide is extremely harmful to aquatic life, including fish, shrimp, and oysters, as described on the package label. 

When rinsing garden and yard equipment that may have come into contact with the weed preventer, be cautious, take care while watering the treated area to prevent the product from running off into nearby water sources or sewers.

Ecological Effects

Commercial herbicide use has a detrimental impact on bird populations in general, but the effects are highly unpredictable and often need field studies to predict reliably. Toxicological effects on birds have been overestimated in laboratory experiments, predicting severe problems that were not observed in the field. The majority of observed effects are due to environmental changes and declines in the abundance of species on which birds depend for food or shelter rather than toxicity.

Herbicide use in silviculture used to favor certain types of growth following clearcutting can cause significant drops in bird populations. Even when herbicides that have low toxicity to birds are used, they decrease the abundance of many types of vegetation on which the birds rely. Herbicide use in agriculture in the United Kingdom has been related to a decline in seed-eating bird species that rely on the herbicide-killed weeds. Excessive use of herbicides in neotropical agricultural areas has been one of several factors implicated in diminishing the utility of neotropical agricultural land for wintering migratory birds.
