As a gardener, you’re likely no stranger to the frustration of dealing with weeds and unwanted plant growth in your garden or yard. Two popular products that can help with this problem are Preen and Roundup. But which one is better for your specific needs? In this article, we’ll delve into the details of each product, exploring their active ingredients, application methods, and effectiveness, to help you make an informed decision.
Introduction to Preen and Roundup
Preen and Roundup are both well-known brands in the gardening and landscaping industry, but they serve different purposes and have distinct characteristics. Preen is a pre-emergent weed preventer and fertilizer, designed to prevent weeds from germinating and growing in the first place. Roundup, on the other hand, is a non-selective post-emergent herbicide, used to kill existing weeds and unwanted vegetation.
Understanding Preen
Preen is a unique product that combines a pre-emergent weed preventer with a fertilizer. The active ingredient in Preen is trifluralin, a chemical that inhibits seed germination and root growth.

What are the main differences between Preen and Roundup?
Preen and Roundup are two popular gardening products used for weed control, but they have distinct differences in terms of their active ingredients, application methods, and effects on plants. Preen is a pre-emergent herbicide that prevents weeds from germinating, while Roundup is a post-emergent herbicide that kills existing weeds. Preen is typically applied to the soil before weeds emerge, forming a barrier that prevents weed seeds from sprouting, whereas Roundup is applied directly to the leaves of existing weeds, killing them on contact.
The choice between Preen and Roundup depends on the specific gardening needs and the type of weeds present. If you’re looking to prevent weeds from growing in the first place, Preen may be the better option. On the other hand, if you’re dealing with existing weeds, Roundup may be more effective. It’s also important to note that Preen is generally safer for use around desirable plants, as it targets weed seeds rather than existing vegetation. In contrast, Roundup can be more hazardous to desirable plants if not used carefully, as it can kill a wide range of plant species.
How do I apply Preen to my garden safely and effectively?
To apply Preen safely and effectively, it’s essential to follow the instructions on the label carefully. Start by choosing the right type of Preen for your specific gardening needs, as there are different formulations available for different types of plants and weeds. Next, apply the Preen to the soil at the recommended rate, typically before weeds emerge in early spring or fall. Make sure to spread the Preen evenly and water it in thoroughly to activate the herbicide. It’s also important to avoid applying Preen to areas with existing weeds, as it won’t be effective against them.
After applying Preen, it’s crucial to maintenance your garden regularly to ensure the best results. This includes watering and mowing your lawn as usual, as well as monitoring the area for any signs of weed growth. Keep in mind that Preen can take several weeks to start working, so be patient and don’t expect immediate results. Additionally, it’s a good idea to reapply Preen as directed on the label to maintain its effectiveness and prevent new weeds from emerging. By following these steps and taking the necessary precautions, you can use Preen safely and effectively to prevent weeds from taking over your garden.
Can I use Roundup on my lawn without harming my pets or children?
Roundup can be used on lawns, but it’s crucial to exercise caution when doing so, especially if you have pets or children who may be exposed to the treated area. Roundup contains glyphosate, a broad-spectrum herbicide that can be toxic to animals and humans if ingested or inhaled. To minimize the risks, make sure to follow the instructions on the label carefully and take necessary precautions to avoid exposure. This includes keeping pets and children away from the treated area until the spray has dried, and avoiding application during windy or rainy weather.
It’s also important to note that Roundup can contaminate soil, water, and air, so it’s essential to use it responsibly and in accordance with the recommended rates and application methods. If you’re concerned about the safety of Roundup or have pets or children who may be at risk, consider alternative weed control methods, such as manual removal or the use of natural herbicides. Additionally, always wear protective clothing, including gloves and eye protection, when applying Roundup to minimize skin contact and eye exposure.
