The Power of Fall Weed Control

Fall is an especially effective time for managing weeds and weed control, particularly of the broadleaf variety, but do you know why this is so?

Here are some of the reasons why:

1. Weed Growth Patterns: Many broadleaf weeds, including perennial varieties, tend to be more actively growing and storing nutrients in their root systems during the fall in preparation for winter. Applying herbicides during this time can effectively target the weeds’ energy reserves and disrupt their growth processes.
2. Translocation of Herbicides: During the fall, broadleaf weeds are actively transporting nutrients from their leaves to their roots in preparation for winter dormancy. Herbicides applied during this period are more likely to be translocated to the roots, leading to better overall control.
3. Reduced Competition: As temperatures start to cool in the fall, many annual grasses and weeds begin to slow down their growth. This reduced competition allows herbicides to target the specific broadleaf weeds more effectively.
4. Less Stress on Beneficial Plants: Fall herbicide applications target weeds without affecting desirable grasses and plants as much. This is because desirable grasses are also slowing down their growth during this time, reducing the potential for herbicide damage.
5. Less Risk of Environmental Impact: Fall often brings more stable weather conditions and lower chances of heavy rainfall. This reduces the risk of herbicides being washed away into water bodies or leaching into the soil, potentially harming the environment.
6. Longer Residual Effect: Herbicides applied in the fall can have a longer residual effect due to the slower growth of weeds. This means they can continue to provide weed control well into the following growing season.
7. Optimal Timing for Perennial Weeds: Fall is an ideal time to target perennial weeds that are storing nutrients in their roots for winter. Effective control during this period can prevent these weeds from regrowing in the next growing season.
8. Integrated Approach: Fall weed control can be part of an integrated approach to managing weeds. Combining fall herbicide applications with other practices like proper lawn maintenance and cultural practices can yield better results.

Types of broadleaf weeds in the Red Deer and Calgary area in Alberta that react well to fall weed control management include:

• Canada Thistle

• Dandelion

• Common Chickweed

• White Cockle

• Burdock

It’s important to note that the effectiveness of fall weed control may vary depending on the specific weed species, the type of herbicide used, and the local climate conditions. Before applying any herbicides, it’s recommended to consult with local gardening or agricultural experts to determine the best approach for your specific situation.
