Can I Use Lawn Fertilizer in My Garden?

Are you left with unused lawn fertilizer after treating your grass? It’s tempting to think that you can repurpose it in your garden, but should you? The answer to this question is not as straightforward as we would like it to be. Every fertilizer, person, and situation is unique, leaving room for debate. Let’s explore both sides of the argument and consider the pros and cons of using lawn fertilizer in the garden.

Lawn Fertilizer for the Garden


Using lawn fertilizer in the garden offers undeniable convenience. Instead of buying separate fertilizers, you can use one product for both your lawn and garden. This means no more cluttered storage with multiple bottles and applicators.


Using the same fertilizer for your lawn and garden makes financial sense. Why buy two products when you can achieve the same results with just one? It’s a win-win situation for your wallet.


Lawn fertilizers are typically more concentrated than garden fertilizers. This means you can apply less product less frequently, saving you time and effort.

Risk of plant burns

Using lawn fertilizer in the garden comes with a higher risk of burning your plants. The compounds in lawn fertilizers are often too strong for non-grass flowers to thrive. This can have a detrimental effect on your garden’s health.

Debatable benefits

Some experts claim that lawn fertilizer is essentially useless for garden plants. This is because lawn fertilizers are specifically formulated for grass, which are more robust and durable than most flowers. However, some gardeners swear by using lawn fertilizer in both areas.

Avoiding Lawn Fertilizer for the Garden

Guaranteed safety

If you’re concerned about the safety of your edible garden plants, using organic garden fertilizers provides peace of mind. These fertilizers are safe for both your plants and yourself.

Gentle on plants

Garden fertilizers are formulated with the delicate nature of plants in mind. They are less concentrated and gentler on both the plants and the surrounding soil. This ensures the health and well-being of your garden ecosystem.

More frequent applications

Due to their less concentrated formula, garden fertilizers may require more frequent applications to achieve the desired results. Depending on your schedule and patience, this can be either a minor inconvenience or a major concern.

In the end, the decision to use lawn fertilizer in your garden is up to you. There is an abundance of evidence both for and against the idea, making it impossible to determine the definitively best approach. It is essential to consider the unique needs of your garden and make an informed decision based on your situation. For more gardening tips and products, visit Ames Farm Center.
