Wash and dry a bottle with a narrow mouth. A 2-liter bottle will work, but if you have intentions of pickling the cucumber for display, a glass bottle is a must.
Slip a small baby cucumber, with the vine attached, inside the bottle. Lay the bottle on its side in the garden soil.
Mound soil around the sides of the bottle to secure it in one place and to prevent rolling. The bottle should remain stabilized in one position.
Shade the bottle with cucumber foliage to prevent it from overheating in the summer sun. A healthy cucumber patch provides ample foliage for shading the bottle.
Allow the cucumber to grow inside the bottle until it reaches the desired size. The size of the cucumber at maturity depends on the cucumber variety.
Harvest the cucumber when it is plump and green, by clipping the vine as close to the bottom of the cucumber as possible. Display the cucumber in a bottle at fairs or agricultural shows. The cucumber will retain its freshness for several days.
