Buy fuchsias from nurseries -- get plants specially bred to be grown in a hanging planter. Read the plant tag or ask sales staff for help.
Buy a hanging planter from the nursery. Some are plastic pots with attached saucers and wires for hanging. Nicer hanging planters are made out of lightweight metal and have coconut husk liners.
Fill the planter with potting soil. Water it well until excess water drips out of the bottom.
Plant the fuchsias. Space plants about 1 inch apart. You want your hanging fuchsia flowers to look lush and full. Use as many plants as you can fit into the planter. Ease plants carefully out of their pots. Use your hands to make holes in the wet soil. Push the plants into the holes, tamping the soil down firmly around their root balls. Water again until the excess drips out of the bottom.
Screw the hook into the ceiling and hang up your plant.
