Lawn Fertilization and Treatment questions, answered by experts

Professional lawn care can increase your home’s value, as it beautifies your exterior and improves curb appeal. Potential buyers who pull up to a house that looks neat and clean will get a great first impression, and savvy buyers will know that a well-maintained exterior is probably indicative of proper care for other things, like electrical, plumbing, and HVAC systems. Ultimately, a lawn that’s professionally cared for can boost your home’s appearance and lead buyers to offer more for your house.

Post-seeding care involves regular watering, mowing when appropriate, and occasional re-seeding to cover sparse areas.

The best time to apply fertilizer to your lawn is in early fall, though some climates necessitate a different schedule. In most cases, avoid fertilizing late into fall, as this opens up your yard to winter injuries and poor health (though this is a great time to kill weeds.) You should avoid early spring fertilization, as this helps the grass leaves grow, but at the expense of developing root systems. Remember to water your lawn after fertilizing to increase its effectiveness and reduce the likelihood of runoff during a rainstorm. 

A quick search online may recommend that you give your dog apple cider vinegar to help decrease the pH level of your dog’s urine. This method won’t help your yard, though. Most turf grasses thrive on slightly acidic soil, so apple cider vinegar won’t make much of a difference. 

The main cause of grass death by dog urine isn’t the pH level anyway—it’s usually the excessive amount of nitrogen that kills your grass.

The best fertilizer for early spring is an organic slow-release fertilizer that sets up your lawn for continued good health and vigorous growth throughout the whole growing season. If your lawn is particularly neglected or has specific issues, you may need an application of quick-release fertilizer alongside a slow-release one for an immediate boost.
