Why Weeds Grow and How to Control Them

What are weeds?

Weeds are defined as any plants that grow in undesirable locations, such as lawns or landscapes.

Why do weeds grow?

Weeds are considered opportunistic and grow when conditions are favorable, such as specific temperatures, lawn humidity, areas of bare or thin grass, and can even grow in cracks in the soil. road, sidewalk or driveway. Weeds are capable of growing wherever there is room. Weed seeds come in abundance and from many sources while also potentially lying dormant in the soil for years before germinating. When actively growing, the weeds produce thousands of seeds per plant and disperse them throughout the season. Some weeds like dandelions are propagated with a little help from the wind. Other sources of weeds include poor quality grass seed purchased from the store and take-out soil for new planting.

Types of weeds

There are three different types of weeds on each lawn and landscape bed. All can be controlled; However, some are easier than others.

Annual weed. These weeds are spread by seeding, germinating and growing for a season, then dying on their own at the end of their life cycle. These include feathered watercress, burdock, passionflower and chickweed.

Two year weed. Biennial weeds have a life cycle of two years. During the first year, a seed germinates and produces a leafy plant. The following year, the plant flowers to produce seeds and then begins the seed life cycle again. These include clover, wild carrot and prickly lettuce.

Perennial weed. These weeds grow for many seasons and are spread by seeding and/or through their root systems. These include dandelion, thistle, and ivy.

How to kill weeds in the lawn

One option is to apply a preventive control before it occurs; however, there is currently no product that covers all broadleaf weeds. Most commonly used as a post-emergence herbicide when controlling weeds in lawns or landscapes. Selective herbicides are another way to get rid of weeds on the lawn. The most widely used selective herbicides work by disrupting chemical processes that occur within weeds. Herbicides mimic a natural plant chemical that stimulates uncontrolled growth. Weed growth happens faster than the plant can handle and dies. The process by which a plant produces energy/food from the sunlight it receives. By blocking photosynthesis, the weeds will essentially starve. Herbicides break the chain of chemical reactions and create toxic compounds inside the plant that cause the plant to die. One type of non-selective herbicide is a chemical called glyphosate, commonly referred to as “Round-Up”. Non-selective herbicides will kill any foliage that has been sprayed. This product should be used with caution to minimize the harmful effects of desired weeds as well as ornamental plants and grasses. The natural way to get rid of weeds in your lawn is to pick them up by hand. On smaller sized lawns and mulch, this is an effective way to control a small number of weeds. If you can pick weeds every year before they flower and produce seeds, you can help reduce the number of weeds that re-grow. Remember that weeds have roots that grow in the ground, use your hands to pull off the upper foliage but the roots are left, then the plant can grow back. You need to get rid of all the roots in order to be successful and this is a hard way to get there.Cultural practices also play an important role in creating a cleaner lawn. Following these simple steps will help keep your lawn as healthy as possible.

Keep your lawn dense. By having a thick, full lawn, you are essentially helping to “stop” the weeds. Weeds grow when there is space for them, and a thick lawn reduces the space available for weeds to grow. Any late-season bare or thin areas should be seeded in early fall (September) every year to thicken the grass.

Fertilize regularly. Proper fertilization helps to feed the lawn and keep it growing and healthy year-round.

Mow the lawn regularly and keep the blades tall. The grass should be 3 – 3 ½ inches long. Cut off the top 1/3 of the blade at a time. This helps to shade the soil underneath the lawn, thereby helping to reduce weed growth. Mow when the lawn needs to be mowed. Don’t mow the lawn just because the lawn is cut every Wednesday. Also, avoid mowing your driveway, path, patio, etc. with a weeder or mower. If the edges are cut too short, they will die off, thinning the grass again creating bare ground and an opportunity for weeds to grow in that area.

Water properly. A lawn with an underground irrigation system should be watered 1 to ½ hour per area twice per week. End sprinklers should be run for 4 hours per area once per week, both resulting in 1 inch of water on the lawn per week. Frequent and short watering will cause shallow roots to weaken the plant. Proper watering helps create a deeper and stronger root system in the lawn, which in turn creates a healthier lawn. To learn more about how to properly water your lawn, check out our watering blog.

Annual core aeration. Core Aeration is a wonderful process that can be done; however, it’s an expensive process, which is why we recommend doing it at least once a year. Core aeration improves the root system of plants, creating an overall healthier plant. It also helps to reduce the hair coat and keep it at its optimum level, providing better air circulation, permeation of water and nutrients to the root zone.

Apply lime when the pH of the soil is low. Keeping the pH in the proper range (6.3 – 6.5) improves the availability of nutrients in the soil, making them more readily available to plants. Here is a great article on the benefits of liming your lawn and having optimal pH levels.

Inference

Weeds are extremely opportunistic plants that can enter your lawn from a variety of sources. The best way to reduce weeds is to have a healthy, bushy lawn. That said, not everyone has the perfect lawn and herbicides may be needed to get rid of your weeds. Herbicides are a cost-effective and effortless way to keep your lawn and landscape weed-free.
