Is fertilizer bad for plants?
While fertilizer is generally a good thing for most plants, there is certainly too much of a good thing. The nutrients fertilizer provides to plants can also damage them if used in excess. But the damage from the misuse of fertilizer doesn't stop at your plants. It creates problems for the environment too, especially aquatic life.
Can fertilizer burn roots?
It is not organic and some plant roots are sensitive to it. But over fertilizing with high-quality fertilizers can also lead to root burn due to an overa bundance of soluble salts in the soil .
What happens if you use too much fertilizer?
Applied too frequently or in the wrong dosage, the fertilizer will lead to the accumulation of too many mineral salts in the soil, and as their concentration increases, it will be more and more difficult for the plant to absorb the amount of water needed. This will automatically slow down its growth or even kill the plant.
How Does Over-Fertilization Affect Plants?
Many do not pay enough attention to how much fertilizer they use because they think plants will take only the quantity of nutrients they need from the soil. Although it seems logical, things do not work this way.
Why do we use fertilizer in potted plants?
We all want our potted plants or vegetables in the garden to proliferate and produce plenty of fruits or flowers, so we often use fertilizers to speed up the process. Although the correct usage of the right fertilizer should not harm the plants, fertilizers are often used improperly or excessively.

What would happen if we stopped using pesticides?
If we abruptly stopped using petro-chemical fertilizers and pesticides on a global scale there would probably be mass starvation and food shortage. Considering that most farming is done on dead soil and requires such chemicals, maintaining production at current levels (in the short term) not to mention increasing output to meet ever-increasing demand due to population growth would not be possible without said chemicals. The population growth over the last 100 years is directly linked to these "advancements" in agriculture that allow us to produce [incredibly low quality] food in great abundanc
