Lawn Fertilizers Have Different Compositions – Here’s How to Choose the Right One

The weather last year caused quite a bit of damage to many Minneapolis area lawns, so it’s only natural to want to correct it. Who doesn’t want a thick carpet of lawn to accent their home’s landscaping? However, one fertilizer doesn’t fit all situations, and the vast variety of products out there can be confusing.

Although nitrogen is the most needed nutrient by grass, it also needs traces of magnesium, sulfur, calcium and others. To determine your grasses needs, keep the following tips in mind.

Soil Test
Your local county extension office should be able to do a soil test for you. This will help you determine the soil’s pH level, along with other measurements. It may also include information on your grass’s phosphorus levels, which is handy in determining the best fertilizer for you.

Type of Grass
The species of grass you have will dictate when and how you fertilize it. However, regardless of the species, it’s best to wait until the soil is warmed to at least 55 degrees for optimal root growth.  If you have warmer weather grass, only fertilize it once it’s actively growing, which would be around six weeks past the last frost date.

Slow Release
To prevent a case of nutrient overload, select a slow release fertilizer. Ideally, at least one third of the nitrogen should be slow release.

Fertilize in Sunshine
To prevent chemical runoff, only fertilize on sunny days. However, it’s best to try organic fertilizers, like blood meal or fish emulsion, instead of chemical alternatives. Compost tea is another good option.

Corn Gluten
Another option to consider is corn gluten. When you put a layer of this down, you’ll be providing your law with much needed nitrogen, and suppressing weeds from growing.

Thick, green grass feels great between the toes and is easy on the eyes. When properly fertilized, it’s also easy to grow.
