"We use Doug regularly to fertilize our trees and shrubs, and to keep pests like lace bug and root weevils under control. He is knowledgeable, punctual, professional, and responds quickly to address any problems that crop up. He even saved our maple tree from verticillium wilt and gave it a good pruning. We highly recommend him."

Lawn Fertilization and Treatment questions, answered by experts

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.

In the fall, you should aerate the soil, overseed the bare spots, kill weeds, mow the lawn low, and rake your leaves. By boosting your lawn’s health in the fall, your grass will be stronger throughout the winter and come back healthier in the spring. You should also trim your perennials so that they withstand the winter and are ready for new growth in the spring. 

There are plenty of products to help green up your grass. Try an iron supplement spray or fertilizer that is rich in nitrogen. You can also apply a thin layer of compost on top of your lawn at the beginning of spring to give the grass a nutrition boost, which helps it achieve that bright color you are looking for. 

Fast-track your seeds to success by pre-soaking them for 24 hours in a shallow container filled with tap water. The water will penetrate the husk and moisten the embryos inside. After one day of soaking, sow the seeds in the soil. Never soak the seeds for more than one day (unless the specific variety calls for longer), as prolonged soaking could cause them to rot.

Yes, but the best approach is to apply fertilizer well before you actually sprinkle the seeds. Apply fertilizer with an NPK ratio somewhere around 10-10-20, or 10-10-10, depending on soil test results and the type of grass you're planting, about six to eight weeks before planting grass seed. This mix added to loosened soil will give the grass seed its best chance of getting off to a solid start.
