Clean a 5- to 10-gallon bucket to use as your hanging flower pot. Drill a 3- to 4-inch hole in the bottom of the bucket to use as your flower opening.
Lay newspaper in the bottom of the bucket to keep the soil from falling through the hole, and cut a 2-inch slice in the newspaper for your flowering planting.
Find a hanging spot where the pot gets the right amount of light for your chosen flowers. Thread twine through the handle of the bucket to hang it from your chosen supports. If there is no handle, drill three holes around the lip of the bucket to use for hanging. Suspend the pot at chest or waist level to complete your planting.
Mix quick-draining potting soil and organic compost in equal parts as your planting soil. Add granular 5-10-5 fertilizer to the soil for more nutrition. This mixture gives both annual and perennial flowers a rich, nutritious and quick-draining foundation for long-term support.
Push the plant's root ball through the newspaper and hole, moving from the bottom of the pot, so that the root ball sits inside the pot while the foliage remains outside. Hold the base of the plant with one hand to keep it in place.
Transfer your soil mixture into the pot with a scoop and pack it around the plant's root ball to secure the planting. Fill the pot to 3/4 full to leave room for watering, and pat the soil down firmly.
Move the pot to its designated hanging height and secure. Water the plant with 2 gallons of water to set the soil throughout.
