Weeds come in all shapes and sizes and can quickly take over a yard, leaving homeowners frustrated and feeling helpless. Fortunately, there are tips and tricks you can use to control and prevent weeds in your lawn and keep it looking its best. From proper mowing and fertilizing techniques to pre-emergent herbicides, there are a variety of methods you can use to keep your lawn free of weeds. With a little knowledge and the right tools, you can have a lush, green lawn that's free of weeds.
What are weeds and why are they so hard to get rid of?
Weeds are simply plants that grow in areas where they aren't wanted. Most weeds are annual plants, meaning they grow and die within one year, which makes them very difficult to kill because they have very short lifespans. Certain types of weeds, such as dandelions, take very little effort to grow and can spread quickly when they are left unchecked, making them extremely difficult to get rid of. For the most part, weeds show up in yards when the soil isn't healthy, when the growing conditions aren't ideal, or when there isn't a good balance of nutrient-rich soil for the grass to grow in. Luckily, weeds can be prevented with a few simple steps to keep the soil healthy and the lawn properly maintained.
Tips for preventing weeds
Keep your soil healthy - Healthy soil is key when it comes to preventing weeds from growing. Keeping your soil healthy means adding nutrients and organic matter, such as compost or mulch. This helps the dirt retain water, which in turn keeps the grass healthy. It also means fewer weeds will grow in your lawn.
Mow regularly - Mowing your lawn at the right height is key to preventing weeds from growing. Mowing the grass too short can actually cause the soil beneath the lawn to get compacted, which can decrease the amount of water the grass gets. Keeping the grass at a healthy height ensures it gets enough water and nutrients, while also preventing weeds from growing.
Fertilize regularly - Adding fertilizer to your lawn at least once a year is essential to keeping your soil healthy and preventing weeds from growing.
Water properly - Just as mowing the grass at the right height is important for preventing weeds, watering the lawn properly is also essential to keeping weeds away. Watering too frequently can cause the soil to get too moist, which can lead to the growth of weeds.
Maintain your yard - By simply keeping your yard clean and maintaining your lawn, you can prevent weeds from growing. Simple things like removing debris, edging the yard, and keeping the grass clippings off the ground help keep weeds from growing.
Mowing and fertilizing for weed control
To prevent weeds in your lawn, mow the grass at the right height and fertilize it at least once a year. For a healthy lawn, you want to mow at a height between one and three inches. If the grass is too short, it might not get enough water, which will cause the lawn to die. On the other hand, if the grass is too long, it might shade the soil beneath it, which can prevent the soil from getting enough water. Mowing at the right height will also make your lawn easier to maintain. You should mow your lawn at least once a week during the growing season. Be sure to clean the mower after each use to prevent the spread of weeds and diseases. Fertilizing your lawn once a year is essential to keep the soil healthy and prevent weeds from growing. When choosing a fertilizer, look for a product that has a high amount of nitrogen, which is essential for growth. Generally, grass fertilizers have three numbers on the bag; the first number represents the amount of nitrogen, the second number represents the amount of phosphate, and the third number represents the amount of potash. A bag with a high amount of nitrogen is ideal for lawns, as it promotes growth.
Pre-emergent herbicides
Pre-emergent herbicides are applied to the soil before weeds germinate. There are two types of pre-emergent herbicides: Coarse pre-emergent herbicides are applied before weeds germinate and remain in the soil for one growing season. Fine pre-emergent herbicides are applied before weeds germinate and remain in the soil for up to three growing seasons. Although pre-emergent herbicides are effective in killing weeds and preventing them from growing, they can also kill your lawn. If you use this method, be sure to follow the instructions on the product label to ensure you apply the herbicide at the right time and in the right amount.
Spot treating weeds
If you have a particularly stubborn weed that isn't affected by pre-emergent herbicides, you can treat the weed with a spot herbicide. Spot herbicides are applied directly to weeds and kill them quickly, as opposed to pre-emergent herbicides, which prevent weeds from growing in the soil. Spot herbicides are ideal for lawns that are already healthy because they won't affect the lawn when applied correctly. That being said, even spot herbicides have to be used correctly for them not to harm the lawn. Be sure to read the label on the product and follow the instructions carefully, and only apply the product to weeds and not grass.
Natural weed control methods
Keeping your lawn healthy and properly maintained is key to keeping weeds out of your yard. That being said, weeds will still pop up now and then. If they do, you can simply pull them out by hand. Pulling weeds by hand can take time, but it is an effective way to eliminate weeds without harming your lawn. The best time to pull weeds is before they have gone to seed and sprouted new weeds. You can also use mulch or compost to prevent weeds from growing in the yard. Mulch is a great way to keep weeds from growing in your yard, but only if it's the right type. You want to use mulch that's coarse and at least two inches thick, such as straw, cedar shavings, or bark.
Pros and cons of chemical weed control
There are a variety of chemicals you can use to control weeds in your lawn. The main benefit of using chemicals to control weeds is that they're quick and easy. You can apply them to the grass as needed, which makes them useful for treating stubborn weeds. On the other hand, chemical weed control methods are harmful to both humans and the environment. Many of the products contain herbicides, which can be harmful to children and pets. If those exposed to the chemicals don't wash the product off their skin, it can cause rashes, blisters, and irritation. The chemicals can also seep into the ground and water table, which can affect other people and animals nearby.
Tips for choosing the right herbicide
Before purchasing a herbicide, it's important to know what type of weeds you have in your lawn. To determine which weeds are troubling your lawn, you can take a sample of the soil to a nearby garden center or purchase an inexpensive kit online. When choosing a herbicide, it's important to look at its active ingredient. The active ingredient is the part of the herbicide that kills the weeds. All herbicides list their active ingredients on the product label, which makes it easy to find the product that contains the chemicals you need. It's also important to note that not all herbicides are safe for all lawns. Some herbicides will harm certain grass types, such as St. Augustine or Bermuda grass. If you aren't sure which herbicide is safe for your lawn, talk to your local landscaper or garden center employees to find the right one for your lawn.
DIY weed control methods
If you prefer not to use chemicals to control weeds, there are other methods you can try. One DIY weed control method is manual removal. Simply grab the weeds by hand when they are small and pull them out of the ground before they have a chance to spread. You can also use a tool to remove weeds that are too deep to pull out by hand. Choose a weed killer that is safe for your lawn and kills weeds quickly. You can also use a weed killer that is safe for lawns, such as vinegar or baking soda. Vinegar and baking soda are both safe for use on lawns when diluted correctly.
