Selecting the Right Cucumber variety for Container

When it comes to growing cucumbers in containers, there are several varieties that you can choose from. 

The type of cucumber you select should depend on your own preferences and needs. Cucumbers come in many shapes and sizes, and some are better suited for container gardening than others.

 

First, consider the size and shape of the cucumber variety. If you’re looking for a smaller cucumber, a pickling cucumber or a bush cucumber might be a better choice than a regular slicing cucumber, which can grow quite large. 

Bush cucumbers stay relatively small, and they don’t require trellising or pruning. Pickling cucumbers have a distinct taste and shape but don’t produce as much fruit as regular slicing cucumbers.

 

Another important factor to consider when selecting a cucumber variety is how cucumbers grow. 

Vining cucumbers require more space and need to be trellised or allowed to climb up a wall or fence. If you are limited on space in your container garden, then bush cucumbers may be a better choice.

 

Finally, consider the flavor and color of the cucumber. Some varieties have a sweet flavor while others have a more bitter taste. 

You may also want to look for cucumbers with different colors and shapes such as lemon cucumbers and long English cucumbers.
 
By carefully selecting the right variety of cucumbers for your container garden, you can have success with growing cucumbers in containers. 

Take your time to research the best varieties for your needs and goals, and you will be sure to reap a delicious harvest!

Selecting the Proper Container for Cucumbers

To grow cucumbers in containers effectively, consider using a larger pot. Choose a container with a height of at least 12″ and a diameter of at least 8″.  


According to square foot gardening, two cucumber plants are allowed per square foot. I have planted two plants in our larger containers without any issues.


We like to use a rather large container for cucumbers. They container dries out quickly in the summer sun and so having a little room to work with is better. 


Whichever container you choose, be sure it has adequate drainage or create your own using a 1/2 drill bit.

Best Soil for Growing Cucumbers

When growing cucumbers in containers, you should start with a high-quality potting mix. We have found adding amendments, such as endo-mycorrhizae fungi, to the potting mix before planting. help create vigorous plants. 

 

We also add Ground Oyster Shell or Dried, Crushed Eggshells for extra calcium. Dried Worm Castings can also be used as part of the container soil mix. 

 

Balanced organic fertilizers like Dr. Earth Organic Tomato, Vegetable, and Bumper Crop Fertilizer can be used to amend the soil when growing cucumbers.

Sowing Cucumber Seeds

When it comes to growing cucumbers in containers, sowing the seeds is the first step. In our larger containers, we plant three cucumber seeds per pot. 

The seeds should be planted about a half-inch deep into the soil. Keep the soil consistently moist until the seeds germinate and you’ll soon have sprouts popping up! 

Once they are growing well, remove all but one plant from each pot.
 
If you’re sowing cucumber seeds indoors, be sure to do it three to four weeks before moving them outside. Planting indoors too early can result in overgrown plants that may try to flower and fruit while still inside. 

Our preferred method of sowing seeds is by using the winter sowing method. When ready to move your seedlings outdoors, carefully slip them from their pots and tuck them into the potting mix without disturbing the rootball. 

Water well, and you’re ready to start watching your cucumbers grow!

Common Pests and Diseases of Cucumbers

Cucumbers are prone to various diseases, one of the most common being powdery mildew. This fungus forms a white powdery mass on leaves and stems and can cause yellow and brown leaves as well as shriveling and dying leaves. 

The spores of the fungus do not affect the fruits directly, however, secondary damage from the disease can cause sun scald or malformed fruits.

To prevent powdery mildew, treat with fungicides such a Neem Oil, and avoid excessive nitrogen fertilization. Make sure plants are not overcrowded. 

Also, practicing strict crop rotation is a good practice to employ to help keep plants healthy. All plant debris should be removed and disposed of far from the vegetable beds to keep the spores from overwintering.

 

Other tips for growing cucumbers in containers is introducing and attracting natural predators to the garden. Predators such as ladybugs, green lacewing and assassin bugs are all good choices to add to your organic pest control arsenal. 

Additionally, it is important to clear nearby weeds and clean the beds of all plant material in the fall and dispose of it away from the garden. 

By following these tips, you can be sure that your growing cucumbers will remain safe and healthy. 

If you have any questions about how to grow cucumbers or prevent common pests and diseases, please contact your local gardening center for more information.

Harvesting your cucumbers

Growing cucumbers is relatively easy, and the fruits should be harvested regularly once they reach maturity. 

 

Cucumbers are ready to harvest when they are 6-8 inches in length and have dark green skins. For best results, try to harvest cucumbers in the morning when the vines are still cool and damp with dew. 

 

If the cucumber fruits have become too large, they can become bitter and tough.

 

At the end of the season, prune off any underdeveloped cucumbers. Store cucumbers in the refrigerator and share them with family and friends if you have an overwhelming bounty.

 

Pickling cucumbers is another great way to store your harvest.

 

With some basic knowledge of how cucumbers grow and proper care, you can successfully grow cucumbers in your garden or containers.
