If you want to keep your lawn looking green, you should use some kind of weed control on your lawn. Some of these methods include using pre-emergent, mowing at a higher height, and using herbicides. But if you don't want to spend a fortune on these products, there are other ways to keep your lawn looking green.
Pre-emergent
Pre-emergent lawn weed control Calgary is a great way to prevent weeds before they start to germinate in your lawn. This herbicide is applied to your lawn before it warms up, so that the pre-emergent kills weed seeds before they grow. These herbicides can be applied early in the spring, before the ground temperature reaches 55 degrees, or as early as the end of fall, after temperatures drop to below 70 degrees. These herbicides will keep weeds out all year, which will make managing them easier.
Several commercial and home weed control products are available to keep weeds at bay. These products contain non-toxic ingredients such as dish soap or vinegar, which will kill weeds without harming your lawn. You can also spray on weeds with salt or a flame torch.
Mowing at a taller height
One of the most effective ways to fight lawn weeds is to mow your lawn at a higher height. Grass that is mowed at a higher height has more shade and competition with weed seedlings, thereby reducing the weed population per unit area. In general, a mowing height of one-third or higher is recommended to prevent weeds from growing. To calculate the best height to mow your lawn, refer to the chart below.
Most lawn mowers have an adjustable height setting. To set it to the proper height, place the mower on a level surface and measure the distance from the ground to the bottom edge of the blade. Make adjustments accordingly, if needed.
Herbicides
There are several herbicides available on the market today that can effectively kill lawn weeds. These chemicals can be applied directly to the leaves of weeds or spread over the soil. If you're not sure which herbicides to use, you can consult a professional. Some herbicides are selective, meaning they kill specific plant species while not harming other plants.
When choosing herbicides, pay special attention to the label. Many herbicides contain chemicals that can harm trees and irritate grass. It's important to read and follow all directions on the label.
Fertilizer
Fertilizer for lawn weed control can be a helpful tool to control weeds and improve the appearance of your lawn. However, you should be careful to only use the right kind of fertilizer for your lawn. The wrong kind can have adverse effects on the ecosystem and can even cause algal blooms. The correct type of lawn fertilizer for weed control is one that is specifically designed to soak into the soil.
Fertilizer for lawn weed control should be applied to a damp lawn at least once every two weeks, but if weeds are persistent, you may need to apply it more frequently. To apply the fertilizer, use a drop spreader. Spread the granules evenly on the lawn. Wait for at least 10 days for the treatment to take effect.
Timing
When it comes to weed control in the lawn, timing is important. The best time to apply a specific herbicide can vary depending on the type and stage of grass growth. The timing chart on the herbicide label will show you when it is best to apply a specific herbicide. You can use this information to plan out your lawn weed control program.
The best time to apply an herbicide to your lawn is in the fall. This is when the soil temperature is between 50 and 55 degrees and weed seeds are most vulnerable to the product. Usually, this means that you should apply a pre-emergent in late fall. If you wait until spring, it will likely be too late, since the weed seeds will have germinated by then.
