Maintaining a property is really hard, especially if you don't have enough manpower or machineries to maintain the wide area or lawn of your real estate property. Cleaning the outside is just as important as cleaning the inside, both do reflect your personality and lifestyle.
That is why most individuals would secure their lawn with the use of weed killers or herbicides to hasten the task. However, this could be really harmful to you and your environment. It was well explained in the article of Arthur Neslen citing new findings of scientist regarding the said products:
EU scientists in row over safety of Glyphosate weedkiller
A bitter row has broken out over the allegedly carcinogenic qualities of a widely-used weedkiller, ahead of an EU decision on whether to continue to allow its use.
Glyphosate is sold and promoted by Monsanto for use with its GM crops. The herbicide makes the company $5bn (£3.5bn) a year, and is used so widely that its residues are commonly found in British bread. Open text source...

There are many alternatives or ways to trim down your lawn, and manual labour is the best way to start doing it. Waging chemical attacks to weeds may not be the best option, and other alternative are presented by Lisa Kaplan Gordon in her article, a more practical and safer methods:
How to Prevent Weeds from Ever Sprouting
Weed seeds "sleep" in your soil all the time, just waiting for sunshine to enable them to germinate. Left underground, many weed seeds remain dormant for years. So the less you disturb the soil, the more likely weed seeds will remain asleep.
The closer together you plant your flowers and vegetables, the less space weed seeds will have to grow. To keep weeds out of lawns, make sure your grass is lush and healthy so weeds have no room to grow. Reseed bald patches; fertilize if a soil test determines nutrient deficiencies; aerate in the fall.

However, if weed problems would still persist after all efforts have been exhausted, it would be better to ask help from expert for a fast and more effective solution, of course without the use of chemicals.
