Lawn Fertilization and Treatment questions, answered by experts

Sulfur makes grass greener as it creates a rich, healthy growing environment. It can help reduce the pH level in the soil to ensure the roots can get all the nutrients they need, such as nitrogen, phosphorus, and potassium. Sulfur also makes grass denser, lusher, and stronger. It’s a soil amendment that can make a big difference in the health and appearance of your lawn.

Lawn care is tough work—even when you hire pros, there’s no guarantee your grass won’t die (unless, of course, your company offers a guarantee). But lawn care companies don’t control the rain or watering restrictions. Your type of grass also impacts the type of care required to keep a lush lawn—and how much that care costs. Talk to a lawn care pro to determine the best times to treat your lawn based on type of grass and your climate.

Hiring a lawn service company can free up your schedule for other tasks and ensure high-quality results. However, doing some of the maintenance yourself can reduce your monthly costs. Another factor to consider if it's worth it is whether you already own lawn equipment and tools you will need to keep your yard looking lush. Ultimately, it depends on your budget, schedule, and the type of tasks you need to complete.

You can thicken new grass by using fertilizer, watering it 1 to 1½ inches per week, mowing when it is at an optimal height, and preventing weeds. You should fertilize your grass while you plant the grass seed, or soon afterward. Use an herbicide to prevent weeds or spot spray with herbicide to kill existing weeds.

The first step in re-doing a bad lawn is correctly diagnosing the problem. That’s why we recommend calling a licensed and trustworthy lawn care company that can help turn your damaged lawn around. Once the problem is diagnosed and fixed, you’ll want to keep up with lawn maintenance by watering, mowing, and feeding your lawn the proper nutrients.
