We understand how tempting it is to try fertilizing your lawn on your own. However, it is not as simple as choosing random fertilizer at the store and applying however much you think your lawn might need. Every lawn is different and the correct levels of nitrogen, phosphorus, and potassium all change depending on the time of the year in Virginia.

Using the wrong type of fertilizer, applying it at the wrong time, and adding too much or too little are all grave mistakes that could end up costing you a lot of money in damage control. Continue reading about these mistakes and how to avoid them with a professional lawn care company.


1. Using the Wrong Kind of Fertilizer

One easy way to tell if you are using the wrong kind of fertilizer is if your lawn is turning yellow or brown after your applications. If it looks like it's dying, it probably is. This can happen if you don't have the proper balance of nitrogen, phosphorus, and potassium in your fertilizer batch.

Each of these key nutrients plays a specific role in any balanced fertilizer formula and the levels your grass needs will change depending on the season. Local professionals know the grass types in the area, therefore, they will know the balance of nutrients that your grass needs to stay healthy.

The grass isn't always greener with DIY fertilization. If your lawn is turning yellow or brown, you are probably using the wrong balance of nitrogen, phosphorus, and potassium.


2. Fertilizing Your Lawn at the Wrong Time

Fertilizing at the wrong time can be detrimental to the health of your lawn. Here are some examples of when not to fertilize:

  • Right before it rains. The water could wash away all the fertilizer, wasting your time and your money. Instead, you should wait until no rain is expected for two days.
  • Too early in the year. This will increase unwanted weeds.
  • Too late in the year. This will cause the grass to be more susceptible to insect infestations, diseases, and weather injury while it waits for its dose of fertilizer.

3. Using Too Much or Too Little Fertilizer

Even if you use the correct fertilizer, it is possible to add too much or too little. Too little fertilizer won't give you the results you are looking for; your lawn will continue to be weak and susceptible to weeds, insects, and lawn disease. Too much fertilizer, on the other hand, will cause different reactions depending on the nutrient:

  • Excess Nitrogen: Too much nitrogen will cause fertilizer burn throughout your grass. This happens because the excess nitrogen will take water away from your grass while leaving mineral salts behind, making your lawn look dehydrated.
  • Excess Phosphorus: When there is too much phosphorus present in your soil, your grass will have a hard time taking up nutrients like iron and zinc. This might cause your grass to turn yellow or possibly die.
  • Excess Potassium: When there's too much potassium in your soil, it will work against the absorption rate of nitrogen and other nutrients in your turf.
