Cucumber is available in two main varieties: greenhouse and outdoor. Greenhouse cucumber plants produce long, smooth fruits, much like the ones you find in the supermarket. These plants don’t need pollinating – in fact, you should remove any male flowers to prevent pollination happening or the plant will die. Outdoor cucumbers, on the other hand, need to be pollinated in order to produce fruit.

This means that they need a female plant to fertilize them, which is why they are often referred to as male plants. The female plants can be found in a variety of places around the world, but the best place to find them is in your garden. However, if you live outside of the United States, Canada, or Europe, chances are that you won’t have access to this type of plant.

The plants should not be allowed to grow more than 2 feet (0.6 m) above the soil surface.

If the cucumbers do not grow to the desired height, they can be pruned back to a height of 2 to 3 inches. After the plants have grown to their desired size, remove them from the ground and place them in an airtight plastic bag. Keep the bag in your refrigerator until you are ready to use them.
