First, read the English article below.

Use a nitrogen-rich fertilizer on your lawn to maintain it and prevent weeds like clover from growing. Fertilizing your lawn once a year in the spring can also help to keep the grass healthy and less prone to weeds and pests. If you notice any small patches of clover growing in your lawn, use a hand fork to dig out them out. Make sure you remove the roots of the clover from the soil so it cannot grow back. Set your mower to a height of 3 to 3.5 inches (7.6 to 8.9 cm) so the grass is not cut too short. Your mower should go no lower than 1 to 1.5 inches (2.5 to 3.8 cm) when you mow your lawn. Keeping the grass tall can help to block out sunlight that can feed clover and other weeds, preventing them from growing. Make sure your lawn stays moist and well hydrated so weeds like clover don’t grow. Give your lawn at least 1 inch (2.5 cm) of water 1-2 times a week in the early morning so it stays healthy. A dry lawn will be starved for nutrients and be too unhealthy to fight off weeds like clover. 

Now, please write a short abstract for it in Vietnamese. Abstract:
