Tips & Advice
What is a noxious weed?
A noxious weed is one that poses a threat to agriculture, horticulture, ecosystems, wildlife, and humans. These weeds tend to grow quickly and multiply rapidly. Ragweed is classified as a noxious weed, and it can cause hay fever. Bittersweet nightshade is also noxious, and produces berries that can be poisonous to humans.
What are non-toxic weed-killer options?
Many weed killers are highly toxic to people and the environment, but there are effective non-toxic options. Direct heat can be used to banish weeds, and flame-weeder tools are available at hardware stores. Table salt can be used to kill weeds by applying it directly to their leaves. You can also kill weeds by spraying them with white vinegar.
How long does it take to get rid of weeds in the lawn?
It can take anywhere from two days to two weeks or more to get rid of weeds on the lawn, usually by using herbicides. With annual weeds, it typically takes two to four days for herbicides to do their work. It can take as long as two weeks for herbicides to kill perennial weeds.
How can you prevent weed growth?
Prevent weed growth by taking steps to prevent the plant's seeds from germinating. Most lawns have been exposed to seeds produced by weeds, but, in many cases, these seeds remain underground without ever germinating. Discourage weed germination by covering your lawn's soil with mulch. Using pre-emergent herbicides can also prohibit weed germination and growth.
What are the most common types of weeds?
One of the most common types of weed is yarrow, which can grow to a height of 20 inches. Another common strain is daisy weed, notable for its spoon-shaped leaves. Lawns that have been recently seeded are vulnerable to creeping thistle, and this weed can be identified by its purple flowers. Another common type of weed is creeping buttercup, which prefers damp soils.
