SACK GARDEN.

The internal irrigation system.

3 x 2L bottles

The bottom bottle must have a wide neck and big cap

Step One.

Bore a 28 mm hole in the cap of the bottom bottle.

Step Two.

Bore a 28 mm hole in the base of the middle bottle.

Step Three.

Bore a 52 mm hole in the base of the top bottle.

Step Four.

Hack a hole in the cap of the middle bottle and screw that cap into the cap of the bottom bottle.

Step Five.

Attach three splints to each of the bottom and middle bottles. Bamboo works well.

Wire or tape them in place.

Step Six.

Fill the bottom and middle bottles with gravel or rocks and connect them by screwing on the cap.

Glue the top bottle into the middle bottle. I used silicone sealer.

Step Seven.

Measure the width of the sack and divide by pi. That will give you the diameter of the base plate.

Step Eight.

Cut out a base plate of the right diameter to give the sack a circular shape. I used an old piece of polystyrene. Wood will work.

Step Nine.Punch or drill 1.5 mm irrigation holes North, South, West and East at the three levels indicated.

Step Ten.

Position the irrigation tower centrally.

Fill with best potting soil.

Pre-irrigate.

Mark out planting stations.

Step Eleven.

Cut horizontal slits about 100 mm long at each planting station and plant your seedlings. I planted 21 plants in a double spiral.
