Can I Use Lawn Fertilizer In My Garden

Planning to use lawn fertilizers in the garden because your neighbors’ backyard has left you envious? That’s because nutrients of lawn fertilizers differ in ratio and content from garden fertilizers. 

Moreover, it also contains herbicides and pesticides that can damage your plants, shrubs, and grass while also killing bees. At times, you may get fertilizers that are free from toxic ingredients, but even then, they can harm your plants. This is simply because they contain either too much nutrients or too little, and either way, they will damage your plants. 

Here are some of the reasons why you must avoid using lawn fertilizer in your garden. Let’s take a look. 

1. Different Nutrients 

Since plants need plenty of nutrients for their growth, it is important to use fertilizers. However, both lawn and garden fertilizers contain these nutrients in different ratios. Also, not all brands add this in the same quantity. 

However, most people go for lawn fertilizers as they are aware of the needs of their garden. But even then, there are chances of getting your soil damaged because of nutrient imbalances. 

2. The Big Three Nutrients 

Generally, fertilizers consist of nitrogen, phosphorus, and potassium (NPK) that are known as the “big three” nutrients. One of the most important nutrients for the healthy growth of plants is nitrogen and abundantly present in lawn fertilizers. 

For root development and to prevent disease in plants, phosphorus is important. However, most lawn fertilizers contain little or no phosphorus at all. So, if you use it in your garden, the roots may not develop adequately, making your plant prone to diseases. 

Potassium supplies strength to the root and stems of the plants, and that’s why it is one of the essential ingredients. Much like phosphorus, many lawn fertilizers also lack potassium. 

3. Iron And Acidifiers 

A number of shrubs and plants, such as blueberries, rhododendrons, and azalea, grow well on acid soils. Lawn fertilizers hardly contain acidifying and iron elements, which is another reason you must avoid them.
