Not every company works like that. But every gardener removes weeds from their edible stuff.

You also cull weak animals for the good of the flock/herd, to avoid dysgenic traits from them being passed down. You also clean your house. You also peel and trim a potato before cooking it.

Gardening and horticulture are ancient human activities that are incredibly old, the act of tending to and cultivating one's garden is a really delightful way to center the mind and get into a place where one is more grounded, connected to nature, and about as disconnected from capitalist interests a thing as you'll find. It's humanizing.

Just because the suits took a metaphor from gardening doesn't mean you have to think like the suits, maybe you want to liberate yourself from the kind of dehumanizing thinking where capitalism rather than nature is the central frame of reference.
