When I was a kid, I loved to pick dandelions. pretty yellow flowers were small, colorful, and looked nice tucked behind the ear! However, if someone has popped up in the front yard, my hair accessory would be considered a crime!
often feel sorry for weeds. They are plants too. In fact, if you flipped through a botany field guide, you might be surprised at the plants you find classified as weeds! But, simply put, a weed is really defined as a plant out of place. Clover in one persons flowing lawn may be considered fashionable, whereas on the other, not. Golf greens are often covered with bentgrass, but if it crawled up some yards, it would be considered weeds.
While perhaps pretty on their own, weeds sticking out like a sore thumb in yards because they can be a different color, size or texture. This is confusing from the beauty or the sprawling green turf. Besides aesthetic value, weeds can also drain nutrients from grass and other plants, and this competition of resources can thin what should be lush. And what's worse is that weeds are fighters. They can withstand conditions that your wishes would not be, and are almost inevitable!
Treating weeds begins with correct identification. There are two classifications of weeds: grassy and broadleaf. These are further broken down into groups like perennial, biennial, and winter and summer yearbook. These, as May gave you guessed it, showing their growing patterns. Grassy weeds, such as sound, like grass. However, they are unwanted grass or grass that grows in different types of grassland. Some examples are annual bluegrass, barnyard grass, crabgrass, creeping bentgrass and foxtail. Broadleaf weeds may appear more to be what most people picture weed-like growth will be. Since they are broad, they are easier to distinguish. Some examples are yarrow, knotweed, chickweed, clover, ground ivy, thistle and my favorite, dandelion.
Once you understand what grows in your lawn and decide that it is unwanted, you can treat it and / or control it. Weeds can actually be controlled by your lawn care maintenance. If you have thick and strong growing lawn, you are already combating the problem. Weeds can be a sign of underlying problems in the environment below. So just by killing them, you are simply putting on a band-aid, not solving the problem.
For example, some weeds grow in situations of compacted soil, such as knotweed. You can also control the growth taking better care of the grass, rather than focus on weeds. You can raise or lower the cutting height, change the frequency of mowing and changing the amount of time between watering. Also, you can increase or decrease the use of fertilizers and soil mixing with air. This will maintain better grass, thus keeping the growth dense and vigorous, which as explained above, does not attract weeds.
In addition to culture practices, sometimes using chemicals needed to control weed growth. In this case, there are several types of herbicides that can be used. Preemergence herbicides will affect the seeds that germinate. Since they are best used two to three weeks before the seeds to grow, and work best to combat annual weeds. Postmergence herbicides are used as a prefix implies, after the weeds have sprouted. Since they must be absorbed through the leaves, this type of herbicide works best with a spray.
It can be used at any time, but are most effective when the weed is still young and growing. Postmergence Selective herbicides are commonly used to control annual, biennial and perennial broadleaf weeds, because they will not damage the grass. However, they can kill trees, shrubs and flowers. These must be used in appropriate conditions, and no rain in the forecast for two days following, air 60-80 degrees and no wind. Finally, non postmergence herbicides kill all types of weeds, and is best used on the face of the grassy weeds that are not affected by selective herbicides.
So the next time you see a Dandelion plant growing, do not make a wish and blow the seeds toward in the direction of the lawn fanatic, they can not get the perfectly manicured lawn they wished!
