Can I Prevent Pigweed From Growing
Preventing pigweed is the best way to control this weed. Since pigweed is a weed that thrives in compacted soil, there are several ways to ensure your lawn stays as healthy and free of weeds as possible.
To deal with the problem before it even starts, you can aerate your lawn and add fertilizer for grass. This will give your grass more space to grow in between the soil, reducing the chance pigweed will find room to take hold.
Mulching is also a healthy option to keep your lawn full and free of pigweed. Mulch prevents the seeds from germinating by preventing them from receiving sunlight.
Cultivation And Flame Weeding
Monitor crops regularly for weed emergence. Cultivate when pigweeds are in the cotyledon stage, or before they reach one inch in height, working as close to the crop row as practical. When the crop is sufficiently established, set cultivators to move an inch or so of soil into rows to bury small weeds. The surface layer of loose, dry soil left by cultivation deters additional pigweed germination. Avoid recompacting the soil, as compaction can promote another flush of emergence .
Figure 11 Cultivation left a dust mulch around these young squash plants, thereby discouraging germination of pigweed and other small-seeded weeds. However, foot traffic recompacted the soil enough to re-establish seedâsoil contact near the surface, thereby allowing weed seeds to imbibe moisture, germinate, and grow in the footprints.

Flame weeding can remove pigweed and other broadleaf seedlings just before crop emergence. It is often used for slow-starting crops like carrot, beet, and parsnip. Because flaming usually does not kill grass weed seedlings, it is not recommended where grasses make up a significant portion of the weed flora.

Where And How Does Pigweed Grow
All of the main forms of Pigweed can be found in almost any country and climate, although they were initially native to the Americas. In the United States, pigweed is a common weed in the Southwestern states, but it can also be found in many other parts of the country, so it can show up in your lawn too!
Pigweed tends to grow quickly during hot summer days as well as during periods of wet weather after a dry spell. They also reproduce rapidlya single plant can produce up to 300,000 seeds each year! Pigweed can also grow to be very high, outcompeting other neighboring plants for sunlight. This type of pigweed tends to grow in damp soil near water sources like creeks, ponds, rivers, or in livestock pastures.
First Noticed Along Waterways
John Newby, who farms in Alabama and Tennessee, says he first starting seeing pigweed up and down the river and along the creeks on his farms. We first thought we didnt have them. We thought maybe we didnt get glyphosate on them because of the rain. But about four years ago, we decided we had them, he says.
Pre-emergence herbicides have worked well, says Newby, and the yellow herbicides have been very effective.
Weve started putting out more liquid nitrogen, putting out the yellow herbicides, and then incorporating with a Turbo-Till, and that has worked really well for us. Once we get that down, we just keep hammering away at it. One thing we might have made a mistake on is that when we went with Flex, we pretty much threw our hoods in the garbage and didnt do any layby or anything for awhile.
But we started going back to that. Weve taking advantage of the incentive program for hoods, and we try to do a better job with our layby, he says.
Resistant Palmer pigweed is a nightmare, says Newby, and growers should do everything possible to stay ahead of it. Youll start out with a small spot. The next year, itll be as big as a pickup truck, and the next year itll be as big as a trailer. Once you get on it, dont let up, he says.
Webster says hell be advising growers to do more incorporating of yellow herbicides. We just need to stay on top of them. I dont think well ever eliminate them, he says.

Common Garden Weeds And How To Kill Them
One of the best ways to get rid of weeds in a garden is to know how to identify the invading plants and learn the best way to kill them. Here are some of the more common hard-to-kill garden weeds and the best methods to control them:
Bindweed is a climbing or trailing vine with small white, pink, or purple flowers. The leaves are variable in shape. The best way to control bindweed is to mulch your garden. But you can also kill this weed by cutting the vine at the base of the plant and digging up as much of the root system as possible. Then, treat the area with a general herbicide that will kill the roots as well as the above-ground growth.
Chickweed is a small, low-growing plant with opposite leaves. The small white flowers have five petals. Chickweed can be killed by using a high-quality preemergence herbicide at the start of the growing season or by hand-pulling young plants before they flower and set seeds.
Creeping Charlie, also known as ground ivy, is a low-growing, creeping plant with round, dark green leaves. The small blue flowers have square-shaped petals. To control creeping Charlie, mulch your garden areas at the beginning of each growing season to keep the spread to a minimum. You can also pull plants by hand or spray them with an herbicide if the weed is already established.
Lambsquarters is a tall plant with arrowhead-shaped leaves and small, green flowers. Lambsquarters can be controlled by mulching, pulling the weeds by hand, or using a general herbicide.

How To Kill Weeds Naturally
If you’re looking for a more natural way to get rid of weeds, there are a few options. One is to pull the weeds by hand. This is the most labor-intensive method, but it’s also the most effective. Be sure to get the entire root system when you pull weeds, or they will simply grow back. Another option is to use a hoe or other tool to chop the weeds down at the base. This method is less labor-intensive than pulling weeds by hand, but it’s not as effective because the roots are still in the ground.
Identification And Growth Habits
Pigweed leaves are egg-shaped or oval and may be red-streaked or covered with fine hairs, depending on the species. Some types are upright but pigweed showing up in lawns is often in the form of low-growing mats. Spiky flowers bloom and produce seeds from mid-summer to autumn.
This plant is a summer annual that completes its entire lifecycle in a single year but one plant leaves many thousands of seeds behind. The seeds can live in the soil for up to 40 years.

Are There Benefits To Pigweed
For those who enjoy foraging for natural foods, pigweed can offer some great opportunities. Almost every part of a pigweed plant is edible. Leaves can be eaten raw as part of a healthy salad, or cooked like spinach and eaten as a vegetable. Pigweed greens are rich in iron, calcium, niacin as well as vitamins A and C.
Pigweed seeds, with vitamins A and C plus calcium. can be eaten raw or cooked as a hot cereal. They can also be ground into flour for baking, and popped like popcorn for a snack.
Always wash collected plants thoroughly before consuming in case they were treated with chemicals.
Guide The Bindweeds Growth
One of the tricks to dealing with vine-type weeds such as Creeping Jenny and Wild Morning Glory is to make sure that any growth is exposed and allows you to kill it for good.
Ensure that any new shoots grow away from your garden plants. Doing so allows the weed to grow to a height that allows you to spray it and kill the root system without harming your carrots, beets, and other veggies.
- Gardening gloves
Hammer bamboo canes around your garden or flower beds at the start of the growing season. When a bindweed vine pokes out of the ground, twine it around one of the canes.
This guidance sends the field bindweed plant growing up the rod instead of a fence or across the garden. It also exposes lots of leaves to your weed killer.

Getting Rid Of Poison Ivy
Poison ivy is another sneaky weed that most homeowners will agree is better left alone. Before you try to get rid of poison ivy in your yard, make sure you identify it correctly. When removing poison ivy, exercise caution.
After youve removed the poison ivy, be sure to properly dispose of the weed. Its vital to remember that poison ivy generates a toxin, urushiol3, that remains active for up to five years, even on dead plants, its sap, and on anything else that rubs up against it. Follow these important guidelines to stay away from urushiol:
- Never burn a mound of poison ivy brush or plants because the smoke emits urushiol into the air, which can cause respiratory problems.
- Poison ivy and roots should be bagged in heavy-duty plastic waste bags and secured so that no one brushes up against the plant, even if you think its already dead.
- Wash your clothes in hot water with a degreasing detergent after weeding poison ivy, and clean non-cloth things with some hot water and a powerful dish detergent.
What Kind Of Common Weeds Are Found In Lawns
Weeds are plants that grow in areas where they arent wanted. They can cause damage to lawns and gardens because they compete with other plants for nutrients and sunlight. Some weeds also spread diseases or attract pests.
Several types of weeds can be found on lawns. The most common weeds include dandelions, clover, crabgrass, and bindweed. These weeds can be easily identified by their leaves, stems, flowers, seeds, and roots. Other weeds such as plantain, thistle, and poison ivy have similar characteristics but look different from the above-mentioned weeds.

Dont Buy Soil That Contains Bindweed
Despite being a weed, Morning Glory sometimes shows up in soil mixtures. This situation can be disastrous, especially if you dont have any weeds in your garden already. New soil can contain bindweed seeds and other nasty plants that dominate your garden if you bring them home.
Its not a good feeling to have been careful in all other respects and still have to deal with weeds popping up. Bindweed in purchased garden soil is an easy problem to resolve, fortunately. Do your due diligence when you pick up potting soil and check the ingredients list.
The soil packaging shows you whats in the soil, so take a few seconds to give it a once-over before making a purchase. A little care at this point saves you hours of bindweed control later in the year.
Cultivate Your Garden Soil To Prevent Pigweed Seedlings From Growing Up
If you are starting your garden in the spring and there are a million little pigweed seedlings sprouting up, running a tiller over them will destroy almost all of them easily. You can do the same thing more accurately with a hoe or a small forked cultivating tool. If the plants are allowed to get bigger it becomes more important to ensure that they are upturned and their roots are exposed else they return to wreak havoc once more.

How Can You Spot Ragweed
Common Ragweed can grow up to three feet tall, has yellow-green flowers, and can be found almost everywhere across the United States.
Its leaves are oval shaped with jagged edges and its roots go deep into the ground making it difficult for other plants to compete with this weed for nutrients. Ragweed has many leaves in a single plant and they look like small but long fern leaves theyre often very green leaves that look like blades with jagged edges.
The flowers are small, green to yellowish in color with four petals. When Ragweed blooms, the flowers head turns into fluffy seed-heads in distinctive clusters that are usually what people notice first about ragweed plants! These seed heads can look like little corn cobs or a bunch of small peas in a row.
The leaves of this plant are covered in pollen so it often triggers allergic reactions in people who suffer from allergies like hay fever.
If you notice these characteristics on any plant in your lawn, then you know what kind of weed it is!
How To Prevent Crabgrass Germination
- Mow at frequent intervals to keep the grass at a consistent length. Check the recommended mowing heights for your type of grass and cut your lawn at the highest recommended setting. Crabgrass requires plenty of light to germinate, so keep the grass as thick and long as possible to create shade near the soil surface. Cutting your lawn too close produces patches where crabgrass and other weeds can germinate.
- Remove no more than one-third of the grass blade at one time when mowing. Removing more not only allows more light to reach weeds, it also can injure the grass.
- In an established lawn, water in long, heavy intervals rather than shallow, frequent ones. Watering on an irregular schedule and only when needed promotes deeper root growth that’s essential to healthy turf grass. Remember that most established lawns require about one inch of water per week from rain or irrigation. If your lawn is newly-seeded, water in shallow, frequent intervals until the grass gets established.
- Fertilize your grass at least once a year, following the package instructions.
