The Difference Between Plant Food and Fertilizer
Like humans, plants need certain nutrients in order to survive. So if you have a plant, and it doesn’t look exactly like it’s thriving, you may decide to give it a little nutritional boost. But does it need plant food, or fertilizer? And what’s the difference between the two? Here’s what to know.

Although the terms are often used interchangeably, plant food and fertilizer are not the same thing. The biggest difference is that plant food is made by the plants themselves, while fertilizer is a synthetic or natural substance that is added to a plant’s soil. Here are a few more specifics:
The easiest way to remember the difference between plant food and fertilizer is that only plants can make plant food: It’s not something that can be purchased (no matter what product labels say). To produce the simple sugar they use as food, plants convert water, carbon dioxide, and sunlight during photosynthesis, and absorb nutrients in the soil through their roots.
When a plant isn’t able to get the nutrients it needs through its soil, it may benefit from the addition of some fertilizer or compost to make up for the nutritional deficits.
The nutrient content in soil depends on a variety of factors, including its texture (loam, loamy sand, silt loam), organic matter content, and pH. Testing your soil is the best way to figure out which nutrients
