Satsuma Tangerines grafted on dwarf stock are the best thing to grow in mid-central Florida. They have thick puffy skin and only a few seeds. Ripen in November before the hard freezes in Dec or Jan. These did not get fertilizer or spray. The secret to large fruit: THIN-OUT the tiny marble sized green fruit in summer before they develop. Take out 1/2 or more, so there's more energy devoted to each fruit.
