How to use it?
Preen is an herbicide that prevents weeds from growing. This ensures it won’t kill weeds in your garden that are actively developing. Furthermore, this weed preventer was created to not accumulate on dirt, drain out, or leach into groundwater.
You should get rid of any alive weeds before using this product. Dig them out by the roots with a weeding fork or trowel. After that, you may begin applying the substance.
When you’ve finished preparing your lawn, apply a coat of Preen Weed Preventer with the supplied shaker scoop to thinly spread the granules over all of your garden surfaces.
Use about 1 ounce of Preen per 10 square feet, or about 20 clear blobs of Preen per square inch, to sprinkle on top of the soil. If water isn’t readily accessible, water the prepared soil directly afterward or rake it softly into the soil. If you’re using water, try not to get Preen on nearby plant foliage, particularly gentle shoots. Even, when dealing with this device, keep pets and kids away from the region.
The pellets can be watered after they’ve been added to ensure that the additives are released into the ground. The best thing is that the granules bind with the soil and form a weed-control shield on the surface of your yard.
Preen may also be sprayed on top of the mulch to help control weeds. The mulch should be spread first, followed by the preventer as directed. Preen Weed Preventer may be watered in or softly raked onto the dirt, holding the pellets away from the plant foliage.
Examine surrounding areas such as the patio, pavement, or driveway after applying Preen Garden Weed Preventer. Sweep up any leftover granules and put them on the soil that has been processed. At least when the watered land is dry, keep livestock and humans away from the treated fields.
When to use:
Apart from the fact that it only has to be used once every 3 months, the Preen Garden Weed Preventer may be used at any time of year. As required, add the preventer per three to four months.
According to some experts, the Preen product performs well when used with a 3-inch mulch layer in the spring until weeds start to spread.
Where to use:
Since it could damage fish and other aquatic species, the manufacturer recommends that it be used in a way that prevents run-off into streams or waterways. This ensures it’s a smart idea to brush some loose granules from your sidewalk or sidewalks.
It can’t be used on flower crops, lawns, vine gardens, or other plants that provide food. Preen can’t be used on or around vegetable or flower seeds since it can discourage them from sprouting. Second, wait until the desired plants are few inches wide. If you’re applying Preen in a vegetable garden, check the instructions carefully since it specifies application times based on the crops you’re growing.
How long does it take to work?
To avoid the growth of weed seeds, this Preen substance usually takes 9–12 weeks after an application. It’s for this reason that it can be used around seeds and new plants. Keep in mind that although Preen Garden Weed Preventer is working, flower seeds will not germinate (during the first 9 -12 weeks after the application).

The Buyer’s Guide
Mode of action

It literally stops weed seeds from germinating and growing branches. No roots, crops, or weeding. The best time to add the first round of Preen is in the early spring, although it’s not the only time to do so. Preen can begin working as soon as you start, stopping the seeds from spreading and rooting.
Ease of use
It is, though, perfectly acceptable if you fail to apply it. As with any weed preventer, Preen may be sprayed on top of mulch if the garden is dry. Simply eradicate all current weeds and grasses from the bedding region before applying the substance.
Efficacy
