What is a Pre-emergence herbicide?
If you’re looking to spend less time weeding your lawn or garden and more time enjoying them, then a pre-emergence herbicide may be the most cost and time effective way to achieve your goal. Pre-emergence herbicides are chemicals that has been developed to help suppress and control weeds before they ever emerge from the soil. They’re designed to work without harming the surrounding landscape plants, regardless of whether they’re ornamentals, perennials, or annuals. Pre-emergence herbicides are particularly useful in container or flower gardens where homeowners may not be able to weed on a daily or weekly basis.
How do I use Pre-emergence herbicides?
Pre-emergence herbicides are very easy to use. Simply apply an even layer of the herbicide to the top of the soil in the landscape bed or container you wish to treat using the amount listed on the bottle, and water thoroughly to activate. the herbicide then bonds with the top 1/2 inch of soil, forming a barrier that suppresses germinating weeds. Plants that are already established are not harmed. This type of herbicide is frequently long lasting (4-8 months), and because of its bonded relationship with the soil, tends to stay where applied rather than running off into the yard. For best results, apply early in the spring before weeds start to germinate.
Use it Wisely
Pre-emergence herbicides are a hand tool for any homeowner, but it is important to remember that no herbicide is able to control everything. Before buying, consider what goal you’d like the herbicide to accomplish – some products are formulated to target only specific weeds, and others to target a broad range. And when it’s time to apply, take the time to clear the application area of as many grown weeds as you can. The pre-emergence herbicides only target germinating weeds; they won’t kill the ones already established.
Tips for choosing a pre-emergence herbicide:
1. Consider Which Weeds You Want to Control – Are you looking to get rid of the dandelions sprouting all over the lawn, or do you need something that will control a wider selection of weeds? There is a range of products available depending on your needs.
2. Buy a Product that’s Been on the Market for Awhile – The market is constantly introducing new herbicides that are ‘better than ever!’ and in all honesty, may be. However there have been incidents where a new product was later discovered to have unforeseen negative side effects on the environment. If that’s a risk you aren’t willing to take, then tried and true products are safest.
3. Take the Time to Read the Label Thoroughly and Carefully – Each product has undergone rigorous application trials at a major university or research facility to determine the best (and safest) rate of application for use. Save yourself time and money by following label directions.
