There are many different types of weeds that can spoil a green and lush lawn: crabgrass, dandelion, white clover, quack grass, wood sorrel, climbing vine, broadleaf banana, cinquefoil and climbing charley, to name a few. . But regardless of the types of weeds you may encounter, getting rid of them can be a challenge.
The best way to eradicate weeds is to use a double approach to apply fertilizers and herbicides at different times of the year. A regular application of fertilizer produces strong and healthy grass plants that are more likely to fight weeds. And it has been shown that herbicides are effective in killing existing weeds and discouraging the growth of new weeds.
Finally, do not rule out the effectiveness of getting on your knees and using the clearing tool to dig up the weeds, especially before they go to the seed. And it is better to pull the weeds by hand when they are still young and their roots have not had the opportunity to grow deep in the soil. Starting older and established weeds requires digging up the entire root system. Otherwise, they will simply grow back.
Before treating or mending a lawn, it is always best to start by testing the condition of the soil. "Do-it-yourself" soil test kits are sold in garden stores, home centers and hardware stores. For more complete tests, contact your County Cooperative Extension office.
If the test reveals that your soil is slightly acidic, increase the pH level by adding powdered lime. To lower the pH of moderately alkaline soils, add organic material, such as peat moss. For floors with extremely high pH, modify it with sulfur or iron sulphate.
It can also remove individual weeds and clumps of weeds using an injection sprayer to spray herbicide directly on the weeds. For best results, apply the herbicide when the air temperature is between 65 and 85 ° F, and there is no rain in the forecast for 24 to 48 hours. And keep in mind that many broadleaf herbicides come in concentrated formulas, which you can mix in the right proportions; Concentrates are also much less expensive than premixed and ready-to-use products.
Inspect the lawn for insect pests. If necessary, apply a grub control agent.
Apply an autumn fertilizer to strengthen the lawn and repair the damage of summer. The leaves of the grass grow much more slowly as the climate cools, but the roots and rhizomes continue to grow. (Rhizomes are the horizontal stems of plants that are just below the surface of the ground).
Treat bare areas with an all-in-one lawn repair mix that contains grass seeds, mulch and a quick-start fertilizer.
Spread a layer of bark mulch over areas where the grass does not grow, but the weeds, like around bushes and under trees.
