If you can't find a coconut palm at a nursery, you can still grow one indoors using—you guessed it—a coconut. You can start this process at any point in the year. To sprout a coconut palm, start with a coconut that still has some of its husk on and sounds full of water when you shake it. Then take these steps: Place the coconut in a bucket of room temperature water, and soak for up to three days to help jumpstart the germination process. Next, bury the nut in a moist but well-draining soil mixture, leaving the top half exposed above the soil. Move the pot to a warm, well-lit area, and continually water it every three days or so to keep the soil lightly moist. With the right environment, you should see a seedling appear through the shell of the coconut within three to six months.
