The Best Time To Kill Dandelions For Effective Weed Control

A large part of maintaining a yard or garden includes weed control. Not only can minimizing weeds create more aesthetically pleasing outdoor spaces, but removing them can also help protect any grasses, vegetables, and non-weedy flowering plants you might have. Dandelions (Taraxacum) just so happen to fall into this category, and they are among the 30 common garden weeds you might come across. When it comes to killing weeds though, timing is everything, and dandelions are no exception. As a general rule of thumb, it's best to kill dandelions with herbicides in lawns during the fall months, but you should also implement other preventive measures throughout the year as well.

Dandelions are perennials known for their multi-petaled yellow flowers that bloom during the spring months and through the early fall. Some people love dandelions for their flowers as well as their many benefits. Among these are food sources for bees, leaves for culinary dishes, and their ability to grow quickly and bloom. However, it's the latter benefit that can also turn problematic, as dandelions can rapidly take over grasses, flowerbeds, and vegetable gardens when left unchecked. They can also potentially spread diseases to other plants, including the tomato ringspot virus. If you're in a situation where the drawbacks of dandelions outweigh the benefits for your yard, it's important to get rid of them during the correct time of the year so they do not take off during the spring months.

If you want to get rid of dandelions from your yard, it is best to apply a post-emergent herbicide before the plants go dormant for the winter. As such, herbicidal control of dandelions is best done during late fall, or around October. While there are many types of weed killers to consider before spraying in your yard, look for products containing triclopyr. Experts believe this ingredient is effective against dandelions specifically. Be sure to follow all instructions on the product label, including safety recommendations.

It's also important to manually remove any weeds that pop up as soon as possible. This method is best for tackling individual plants at a time. It's also the safer strategy for killing dandelions in vegetable gardens and flower beds, as herbicides may potentially kill other plants nearby. You can pull dandelions out of the ground any time of the year. One common mistake is to pull the top of the weeds only. You will need to pull out the roots as well, otherwise the dandelions will inevitably come back.

Regular lawn maintenance is another way you can help prevent dandelions year-round. In fact, having a yard full of dandelions can mean your lawn is in poor condition. Overall, dandelions can survive in tough conditions, but they are known to especially grow in thin lawns, disturbed soils, and soil with poor nutrients, as well as overly wet soil and warmer conditions overall. These weeds are less likely to thrive in a healthy lawn that is mowed, fertilized, and watered consistently.
