When I capture a town, I immediately set sail for the nearest English settlement and talk to the Mayor who tells me he's going to be the new Governor of the the place I just conquered, which I consequently escort him too.
Then I go back to the settlement and speak to the new Mayor. He's told me to take seedlings from the settlement to my new territory to promote better crops.
The Tavern keeper has told me things also, like go to the nearest Jesuit settlement, as there are immigrants needing an escort to my new territory. After a few runs like the above, the local economy is normally flourishing and very wealthy.
Even if you've installed a new Govenor, sometimes you need to replace him with a new one to get the economy strong. The Tavern keeper normally tells me when I need to do this.
