Something I haven’t seen mentioned is a weed killer called [2,4-d](https://en.wikipedia.org/wiki/2,4-Dichlorophenoxyacetic_acid). The process kills weeds by making them grow at an unsustainable rate. The plants grow until they die due to not having enough nutrients or energy. The process is very efficient and 2,4-d is one of the most popular lawn care chemicals for weeds.
It is also extremely controversial not only as a herbicide but because of its usage in the chemical weapon agent orange.
Not similar. Most plants don’t create storage for excess energy based on just nutrient consumption. They are efficient in that all nutrients taken up will be put toward growth or fruit. The exception would be biennials perrenials, though their energy storage mechanisms are usually subject to environmental cues rather than just nutrient uptake. Onions will bulb out based on the amount of daylight they receive, and will then use the bulb as an energy store over winter. Most of your flower bulbs behave similarly. Trees will create large stores of sugar as daylight hours shorten and the weather cools. This not only feeds the tree, but the sugar and some proteins act as a sort of antifreeze to keep its cells from rupturing due to ice formation.
