Lawn Fertilization and Treatment questions, answered by experts

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. 

The best fertilizer for thick Bermuda grass is an organic fertilizer with an N-P-K ratio high in nitrogen, low in phosphorus, and low in potassium. Organic fertilizers help Bermuda grass grow stronger and healthier by retaining water well, supporting microbiome life, and promoting long-term soil health. However, this type of fertilizer is more expensive than synthetic fertilizers. 

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. 

Yes, after the lawn is overseeded post-aeration, most of the seed germinates in the aeration holes. This leaves the soil undisturbed while lush and healthy grass will grow in the holes' place. The point of this is to create extra turf density in areas that really need it, such as a large patch of dead grass where a shed used to be.

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.
