How To Grow Cucumber Vertically – Save Space & Increase Yields in 3 Simple Steps

Can you grow cucumbers vertically? Yes you can! Growing Cucumber vertically will increase yields and provide more uniform cucumber since the cucumber is not growing on the ground. With these tips, you can grow cucumber vertically at 2 plants per square foot!

Here is a photo from my garden using the method to grow cucumbers vertically in 2018 – this photo was taken toward the end of the growing season in September. This should give an idea of how high the cucumbers climb when growing cucumbers vertically. When they get to the top, they also grow horizontally over the top of the garden trellis.

There are three key steps to growing cucumbers vertically:

Step 1: To Grow Cucumbers Vertically Build a Structure


To build a structure for growing cucumbers vertically, you do not need anything elaborate or expensive. A simple trellis or sticks arranged in an A-frame shape will suffice. You can even use simple garden fencing or cattle panels. If you prefer a more elaborate structure, you can follow our video tutorial on building a conduit frame. This type of frame is made from electrical conduit pipes and can be customized to fit your specific needs. It is a sturdy and cost-effective option for supporting your cucumber plants as they grow vertically. For more detailed instructions on building a conduit frame, check out our in-depth article on the topic. With these options, you can easily create a structure that will support your cucumber plants and help them grow to their full potential.

If you decided you don’t want to build your own trellis, another option is to purchase a simple trellis to help your cucumber plants grow vertically, there are plenty of options available on Amazon. A quick search for “cucumber trellis” will yield a variety of options to choose from. Some trellis options are made from sturdy materials such as metal or wood, while others are made from more lightweight materials like plastic or netting. Consider factors such as the size of your garden, the weight of the trellis, and the type of plants you will be growing when selecting a trellis. With so many options available, you are sure to find a trellis that fits your specific needs and budget like this foldable one pictured below.

Step 2: Grow cucumber vertically by training the cucumber up the string

To train your cucumber plant to grow vertically, start by tying a string loosely around the base of the plant if using a string trellis or weaving the plant up the structure. As the plant grows, guide the tendrils up the string using gentle pressure. Once the tendrils start to grow, the plant will begin to climb on its own. If you have enough vertical space, you can train the plant to grow up multiple strings by repeating this process. It is important to use gentle pressure and avoid tugging or pulling on the plant, as this can damage the stem and hinder growth. By following these steps, you can effectively train your cucumber plant to grow vertically and maximize your garden’s productivity.

Step 3: Prune When Growing Cucumbers Vertically

To maximize the health and productivity of your cucumber plants, it is important to prune the lower leaves and train the vines as the plant grows. Removing excess leaves will allow for better airflow and can help prevent disease. Once the plant reaches the top of the trellis or support structure, guide the vines down the edges and trellis them over the sides to continue supporting the plant’s growth. By following these steps, you can help ensure that your cucumber plants thrive and produce a bountiful harvest.

Square Foot Gardening Cucumber: Optimizing Your Garden Space

Square foot gardening is a brilliant method for maximizing your garden space and ensuring a bountiful harvest. When it comes to growing cucumbers in a square foot garden, there are some key strategies you can employ to get the most out of your efforts. Let’s dive into the essentials of square foot gardening cucumbers, focusing on planting density and mulching practices.

Planting Density: Two Per Square Foot

One of the main principles of square foot gardening is efficient use of space. For cucumbers, this means planting two plants per square foot. This density ensures that each plant has enough room to grow and access the necessary nutrients, without wasting valuable garden space. By planting at this density, you can optimize your yield and make the most of your square foot garden.

Heavy Mulching: The Secret to Healthy Plants

Mulching is a crucial practice for any successful garden, especially in square foot gardening. Cucumbers need consistent moisture to thrive, and heavy mulching helps retain this moisture in the soil. Organic mulches, such as straw, grass clippings, or shredded leaves, are ideal because they decompose over time, adding valuable nutrients back into the soil. Additionally, mulching helps suppress weeds, reducing competition for water and nutrients.

Planting Tips for Square Foot Gardening Cucumbers

  1. Start with Quality Seeds or Seedlings: Choose cucumber varieties that are well-suited to your climate and growing conditions. If starting from seeds, ensure they are fresh and of good quality. If using seedlings, select healthy, disease-free plants.
  2. Prepare the Soil: Ensure your garden bed is well-prepared with rich, well-draining soil. Incorporate compost or organic matter to improve soil fertility and structure.
  3. Planting: When planting, make small mounds in each square foot section. Plant two cucumber seeds or seedlings in each mound. The small mounds help with drainage and keep the roots slightly warmer.
  4. Watering: Water your cucumber plants consistently, ensuring the soil stays moist but not waterlogged. Cucumbers require about 1 inch of water per week, more if the weather is particularly hot or dry.
  5. Support Structures: As cucumbers grow, they will need support to climb. Utilize trellises, A-frames, or other vertical structures to train the plants upwards, saving space and promoting healthier growth.
  6. Fertilizing: Feed your cucumber plants with a balanced fertilizer or compost tea every few weeks to keep them thriving throughout the growing season.

By following these planting tips and focusing on optimal density and mulching, you can ensure a productive and healthy square foot garden filled with delicious cucumbers.

Q: How many plants can I grow per square foot when growing cucumbers vertically?

A: You can grow two plants per square foot when growing cucumbers vertically.

Q: When is the best time to plant cucumbers?

A: Cucumbers should be planted after the threat of frost has passed and the soil has warmed to at least 60°F. In most areas, this is usually around mid-spring.

Q: How often should I water cucumbers?

A: Cucumbers need plenty of water, especially when they are flowering and fruit is forming. Water the plants deeply about once a week, or more frequently during hot, dry weather. Make sure to avoid getting water on the leaves, as this can lead to fungal diseases.

Q: How do I know when cucumbers are ready to harvest?

A: Cucumbers are ready to harvest when they are firm and have reached their desired size. This can vary depending on the variety, but most cucumbers are ready to harvest within 60-70 days after planting.

Q: Can I grow cucumbers in pots?

A: Yes, cucumbers can be grown in pots as long as the pots are large enough to accommodate the plant’s root systems. Choose a pot that is at least 12 inches deep and wide, and make sure it has good drainage. Cucumbers will also need a sturdy trellis or support system in the pot to grow vertically.

Q: How do I get my cucumber plants to produce more?

A: Here are several tips:
1. Provide the plants with adequate sunlight: Cucumbers need at least 6 hours of sunlight per day to produce well.
2. Water consistently: Cucumbers need plenty of water, especially during the flowering and fruit-forming stages. Water the plants deeply about once a week, or more frequently during hot, dry weather.
3. Grow plants in rich soil amended with organic compost.
4. Prune the plants: Removing excess leaves and thinning out the plants can help improve air circulation and increase fruit production.
5. Provide support for the plants: Cucumbers need a sturdy trellis or support system to grow vertically. This will help the plants grow upright and produce more fruit.
6. Choose the right variety: Some cucumber varieties are more productive than others. Look for varieties that are known for high yields and try to plant multiple varieties with different maturity dates to extend the harvest season.
7. Harvest Frequently: Harvesting frequently ensures continuous production, letting the cucumbers get big on the vine will reduce production.
