Strawberry planters have room to grow several plants in one container. There are several different strawberry planter designs, but most have openings around the sides of the planter so strawberry plants can be planted through the sides as well as from the top. You can make your own strawberry planter from household containers, terracotta planters or ceramic urns. Strawberries can be invasive plants; growing them in planters keeps them in check. Another benefit of growing container strawberries is that the fruit does not lie on the ground while it ripens.
Remove the advertising from the outside of the coffee can. Clean the inside and outside of the coffee can with household cleaner. Dry the can.
Drill six 1/4-inch diameter holes in the base of the coffee can. These are the drainage holes for your strawberry planter; space the holes at least 1 inch apart around the bottom of the can.
Measure and mark opposite sides of the can 4 inches up from the bottom rim. Turn the can a quarter turn. Measure and mark opposite sides of the can 7 inches up from the bottom rim. You will have one mark on the north, south, east and west positions of the circular can.
Drill 1-inch holes over each mark on the can.
Cover the bottom of the inside of the can with a flattened coffee filter. The filter will prevent the soil from escaping as you water the strawberries.
Fill the can with a 3-inch layer of potting soil. The top of the potting soil should be beneath the first two holes in the can.
Insert the roots of one strawberry plant into each of the holes placed 4 inches from the bottom rim. Place a portion of a coffee filter around the openings between the strawberry plant stem and the can. Add 3 more inches of potting soil to your strawberry planter.
Insert the roots of two more strawberry plants into the holes drilled 7 inches from the bottom rim. Add coffee filters to block the openings. Add two more inches of potting soil to the strawberry planter.
Position the remaining two strawberry plants upright in the top of the planter. Fill in around the plant roots with potting soil. Leave 1 inch of open space at the top of the planter so that water will not overflow.
