Lawn Fertilization and Treatment questions, answered by experts

The quickest way to kill weeds is to burn them, pour boiling water on them, or pull them out by hand. Each of these methods works instantaneously. Beyond that, using vinegar for grass works in a couple of hours, as do herbicides you can buy at the store. The slowest way to kill weeds is to starve them of nutrients and sunlight with mulch or fabric covers.

You should put pre-emergent herbicide and fertilizer on your lawn in the spring. Pre-emergent herbicide keeps weeds from taking root. Fertilizer helps your grass to grow lush and dense and blocks future weeds from growing. You can also add amendments, such as sulfur and lime, to enhance your soil quality. 

While you may see some germination by simply tossing a handful of new seeds on a lawn, you'll have more success by following the proper reseeding or overseeding process step-by-step. Without properly tilling, mowing, amending the soil, and watering your lawn, the new seed could blow away or simply fail to take root.

First, make sure you’re watering your grass early in the morning (and keep in mind you don’t have to water every day). Doing this helps ensure the water is able to soak in before the hot temps evaporate all of the water. Also, when you mow, don’t mow your grass as short as you would in non-drought conditions. Taller grass can help slow down the rate at which soil dries out. Finally, take your leftover lawn clippings and spread them out across the lawn to give it a little extra shade and nutrients.

Too much clover in your lawn can indicate several issues with your soil. Clover can thrive in soils with abnormally high pH, low-cut grass, and low nitrogen. Amending these issues can push clover out for good.

Hardy perennial clover loves the low nitrogen and compact conditions that often come with poor, infertile soils. But other factors also contribute to a clover explosion, including drought conditions, cool temperatures, under fertilization, and over-irrigation. You’ll need to evaluate all these elements when planning to kill off the clover.
