Eli5 Why are weeds so hard to kill while desirable plants so hard to keep alive?

Question

Weeds grow, well, like weeds, out of the cracks of the pavement with nothing but municipal runoff to keep them alive. Meanwhile I have to work tirelessly to keep my tomato and pepper plants happy and fruitful. Why do weeds dominate a garden?

Answer 1

A weed is just a plant you don’t want there, corn in a wheat field is a weed, so as long as your goal is to grow a specific plant you will have weeds that generally are more suited to that environment
