Meaning

Jefferson is arguing that political freedom is not self-sustaining. It requires periodic sacrifice and struggle to remain alive. The image of blood refreshing a tree is deliberately stark: he is saying that uprisings, even violent ones, are a natural and necessary part of keeping a republic healthy. Both the citizens who fight for their rights and the rulers who abuse power pay a price, and that price is what renews the system.

Context

Jefferson wrote these words in a private letter to William Stephens Smith in November 1787, shortly after learning of Shays' Rebellion, an armed uprising by Massachusetts farmers protesting debt and taxation. Rather than condemning the rebellion outright, Jefferson treated it as evidence that civic energy was still alive in the young republic. The letter was personal and informal, which gave Jefferson room to express a more radical view than he might have put in an official document. The sentiment reflects his broader belief that government should be kept in check by an engaged and occasionally rebellious citizenry.
