Can plants grow without fertilizers?
But scientists have been growing plants without fertilizers. We all learn that plants can make their own food via a complex process called photosynthesis.

Compost and manure are excellent nitrogen sources that also improve soil. Nitrogen is a very important nutrient for plant growth. It encourages lush growth of leaves and stems as well as providing a dark green color to the plant.
Is Fertilizer Really Necessary?
Fertilizers provide naturally occurring elements like nitrogen, phosphorus, potassium, iron, calcium, and magnesium. It is only when your soil’s nutrient levels become depleted that fertilizing becomes necessary.
Do plants grow better with fertilizer or without?
Sometimes, your soil may have the nutrients your plants need——especially if you’re working with fresh potting soil or a newly dug garden bed. Fertilizer is especially needed as a source of nitrogen, as well as potassium and phosphorous. Plants use up these elements quickly, nitrogen in particular. That’s why fertilizer is needed to replenish them. Without plenty of these elements, plants can grow, but they won’t be as healthy as they are when they have everything they need.
How do I know if my plants need fertilizer?
There are several visual cues that mean your plants need to be fertilized. If the foliage isn’t as dark green as it once was and the older leaves are turning yellow, the plant is low on nitrogen. Pale green leaves with darker veins running through them are a sign that your plant needs potassium. A lack of phosphorus is evident when older foliage begins to turn purple at the base and other leaves look dull. All these missing elements can be provided with fertilizer.
What happens if too much fertilizer is used?
Administering too much fertilizer can result in fertilizer burn, which dries plants out because the excess fertilizer keeps plants from being able to take in the water they need, even when water is available . If your plants have fertilizer burn, you can flush the excess fertilizer from the soil with plenty of extra water, going above and beyond the moisture your plants need to survive.
Why Fertilize?
Now that we’ve established that fertilizer is not plant food as most fertilizer companies would have you believe, but more accurately described as a supplement for plants, you may be asking yourself why you need to fertilize your plants at all.
Can you over fertilize a lawn?
It’s definitely possible to use too much fertilizer on your lawn, with results that can be disastrous, including death of the grass. Other symptoms that your lawn has had too much fertilizer include discoloration, overlapping spreader rows, or stripes in the grass. These things happen because over time, the salts in the fertilizer accumulate in the soil, drying the lawn out in a process called “fertilizer burn.” The more discolored your lawn is and the longer you wait to take action, the less likely it will recover from overfertilization.
What happens if you don’t fertilize plants?
The most obvious consequence of not fertilizing your plants is that, for vegetables and herbs, your harvest will be reduced. Plants that get enough fertilizer will produce the maximum they’re able to, so failing to fertilize means you’ll see fewer vegetables, fruits, or usable herbs throughout the season. Plants that aren’t fertilized will also be less visually appealing than fertilized plants, because healthy plants produce more foliage and blooms. Plants that don’t get fertilizer may also be malnourished, which makes them susceptible to infestation by garden pests and makes them more likely to catch plant diseases. The eventual repercussions of infestation or disease can range from harmless cosmetic issues to more severe effects—including damage to plants and even their death in some cases.
Getting the Nitrogen Fix
For several decades, plant scientists have been trying to engineer cereal crops to fix their own nitrogen, meaning they insert new genes into cereals that enable them to fix nitrogen.
