Can You Use Lawn Fertilizer On A Vegetable Garden?

So, can you use lawn fertilizer on a vegetable garden? In a word, no.

Lawn fertilizer is not typically recommended for vegetable gardens because the chemicals in the fertilizer may inhibit growth of plants.

However, some people have had success using it with some adjustments to their garden layout and fertilizing schedule. I don’t recommend doing this this unless you are extremely experienced and know what you’re doing.

Lawn fertilizer is not the best option because of the chemicals in the fertilizer. My advice is this is a “horses for courses” scenario. Use lawn fertilizer for what it’s intended to be used on…lawns.

The best way to fertilize your vegetable garden is by using compost which contains naturally occurring minerals and nutrients for plants.

Composting is a great way to create an organic fertilizer that will give your vegetables everything they need without having to worry about any harmful chemicals.

Why Can’t You Use Lawn Fertilizer On A Vegetable Garden?

Fertilizer is a solution that is used to provide nutrients to plants.

It can be organic or chemical in nature.

However, there are some fertilizers that are not suitable for use in a vegetable garden.

One of the reasons why you can’t use lawn fertilizer on a vegetable garden is because it contains nitrogen, which is not needed by vegetables.

It also contains phosphorus and potassium which are not necessary for vegetables either.

Some other reasons you shouldn’t use lawn fertilizer on your vegetable garden are because it may contain weed killer or insecticide, which will kill your crops and may harm your health too.

Lawn fertilizer also has high levels of salt, which will harm the soil quality in your vegetable garden and make it unsuitable for growing vegetables at all.

Other reasons not to use lawn fertilizer on your vegetable garden are that it won’t help improve the flavor of your produce, and it won’t promote healthy plant growth.

So, in answer to the question, can you use lawn fertilizer on a vegetable garden, again, the answer is no, it’s not a good idea.

What Is The Best Fertilizer For Vegetable Gardens?

The best fertilizer for vegetable gardens is compost.

Compost is a mixture of organic matter, soil, and water. It is created by the breakdown of organic matter by microorganisms.

Compost can be used to fertilize plants because it contains many nutrients that are beneficial to plant growth.

The nutrients in compost are nitrogen, phosphorus, potassium, calcium, magnesium and other trace minerals.

When you add compost to your vegetable garden, it will provide these essential nutrients for the plants.

This means that you can cut down on having to buy expensive fertilizer products from the store anymore.

You can make compost yourself. It’s not that difficult, in fact it’s easy with a little practice.

Simply add things like kitchen scraps including fruit peels, egg shells, coffee grounds, tea bags, bread crumbs, pasta, rice, meat, fish bones, etc. to your compost bin.

Here’s a short tutorial on how to make compost at home.

How To Apply Compost To Your Vegetable Garden

  • Mix compost with topsoil before applying it to the ground.

Yes, composting is safe.

There are no dangerous chemicals in compost. In fact, there are several benefits to using compost instead of chemical fertilizer.

One benefit of composting is that it helps reduce pollution. By using compost, you don’t need to purchase as much chemical fertilizer.

Another benefit of composting is its ability to increase the fertility of soils. Using compost as a fertilizer will allow you to save money when buying fertilizer.

A third advantage of composting is that you can reuse the compost.

If you do not want to use the compost after it has been turned into soil, then you could sell it or simply give it away to family and friends who need compost for their garden.

Conclusion: Should You Use Lawn Fertilizer On Your Vegetable Garden?

Most experts recommend against using lawn fertilizer on vegetable gardens. Some of these same experts suggest if you are growing tomatoes or peppers, it may be okay to use lawn fertilizer.

I don’t want to argue with the experts but again, only do this if you are a “ninja” gardener and know what you are doing. 

As I said above, leave the lawn fertilizer to do what it’s supposed to do…help lawns!

Finally, the reasons not to use lawn fertilizer on a vegetable garden are:

First, it contains nitrogen which can be harmful to plants if used in large quantities. It also contains phosphorus which can lead to an overgrowth of weeds in the garden. Finally, it has salt which can make vegetables taste bitter and salty.


It will not improve the flavor of the vegetables.

It more than likely will not help prevent diseases from attacking the plant.

And it will not increase the yield of the crop.

So next time you see someone asking if you can use lawn fertilizer to feed your vegetables, just smile and say, “No thanks!”

Growing up on a farm gave me and my family some huge advantages. One of them was learning to grow our own food. Apart from acres and acres of crops, we had a magnificent fruit and vegetable garden plus, we canned our own food. I’m hoping to pass on some of this expertise and experience to you.

  1. It’s great to learn that a lawn fertilizer can help your plants flourish because it contains nutrients that promote plant growth. I first learned about these in a movie that I binged with my girlfriend yesterday, and now she’s interested in transforming her garden. I’ll probably suggest that she look into different lawn care providers that offer these services someday.
