Pruning a cucumber plant helps to promote air circulation and prevents the spread of disease. It also allows the plant to direct its energy into producing fruits, rather than leaves.

What You’ll Need

-Pruning shears
-Loppers (optional)

Before you start pruning your cucumber plant, make sure you have the right tools on hand. You’ll need a pair of pruning shears to get started. If you’re dealing with a particularly large plant, you may also want to use a pair of loppers.

When to Prune

Early in the season, focus on removing any diseased or damaged leaves, as well as suckers (random shoots thatgrow in the leaf axils). Suckers compete with cucumber fruits for energy and water. You can identify them by their lack of cucumber leaves; they typically have little if any flowering activity.
As the cucumber plant begins to vine, you’ll need to provide support. This can be done with a stake or by training the plant up a fence or trellis. Once the plant has begun to vine, you can begin to prune it. Cucumber plants produce female and male flowers. The female flowers will produce cucumbers while the males will not.
To increase your chances of getting female flowers, remove any early-season male flowers that are produced before July 1st in most areas of North America . After this date, remove any remaining male flowers that are produced along with the suckers as described earlier.

How to Prune

Cucumber plants can be pruned in a number of ways to improve yield and fruit quality. When and how you prune depends on the type of cucumber plant, the training system being used, and the height of the plant.

Pruning encourages the plant to produce lateral (side) branches which bear fruit, rather than continuing to produce vertical growth. Lateral branches are typically shorter and produce more fruits that are uniform in size and shape.

Vertical growth results in fewer fruits that are often longer, thinner, and misshapen. It is important to remove any vertical growth that appears after pruning so that the plant will continue to produce lateral branches.


Pruning cucumber plants helps to increase air circulation, which reduces the chances of diseases such as powdery mildew. It also helps the plant to focus its energy on producing fruit, rather than foliage. When pruning, always use clean, sharp shears to make clean cuts. Make sure to remove any diseased or damaged leaves and stems, as well as any leaves that are crowding the plant.
