Can too much nitrogen harm plants?

But as with everything, balance is key: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants, and can also harm our environment. Plants that do not have enough nitrogen become yellowish and do not grow well and can have smaller flowers and fruits.

How do you know if a plant needs nitrogen?

The first way is to take a look at the leaves. If the leaves are yellowing, this can be a sign of chlorosis — which could also be a sign that your plant is in need of nitrogen. Keep in mind, however, yellowing leaves can also indicate a few other issues (like overwatering). The second way is to perform a soil test.
