A 5 gallon bucket makes a good planter. Just drill holes in the bottom or put rocks in the bottom to ensure drainage. It can be made into a Vertical Planter by cutting three 2" holes 4" from the bottom of the bucket, and then another row 4" above that, offset from the first row - shorter buckets will accommodate 2 rows, taller buckets will accommodate 3 or 4 rows. Fill with potting soil, and plant the top with plants, and transplant individual plants into the holes in the side. Make sure to water thoroughly each time you water.
