Lawn Fertilization and Treatment questions, answered by experts

Yes, it’s always a good idea to fertilize your lawn before a major leveling project. This step gives your grass the nutrients necessary for healthy growth, helping it recover and replenish itself faster. However, you should do this at least three weeks in advance, as the leveling process can disturb the newly-applied fertilizer.

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 type of fertilizer depends on the type of grass and your desired end result. Generally speaking, slow-release fertilizers are best for grass, as they gradually release nutrients into your soil instead of all at once, which meets the needs of many grass types. However, the tradeoff is that slow-release fertilizers contain phosphorus, which negatively impacts local water quality. Also, some grasses require different formulations to meet the demands of the soil. Test your soil to see how acidic or alkaline it is before choosing a fertilizer. 

Whether or not grass will fill in bare spots itself depends on the type of grass you have. For example, grass with rhizomes (e.g., Bermuda grass) and stolons (e.g., Saint Augustine grass) will naturally fill in bald spots as it spreads laterally. However, clump-forming grasses will not spread. 

If your lawn and general landscape are struggling, consider calling a local landscape specialist to suggest lawn amendments, local plants, and hardscape changes to boost the long-term health of your outdoor space. While you may be able to take on small projects yourself—such as reseeding your lawn or testing the soil—a professional can help you build a plan to bring a struggling yard back to life quickly.
