How Many Cucumber Plants Per Square Foot: Guide For Planting Cucumbers


Two seeds or transplants per square foot spaced 6 inches apart

You should have two cucumber plants per square foot with 6 inches of space apart towards the middle of the square to ensure that they’ll have enough room to grow. You can use the square foot gardening method on any greenhouse size, and it should provide you many benefits. In general, square foot gardening allows you to care for the cucumbers more conveniently. 

They will be as productive even if space is smaller than a traditional gardening method. Remember that one cucumber plant can produce up to three pounds of cucumbers. Therefore, if you’re thinking of productivity, having two plants should feed one person well. 

Many gardeners also note that cucumbers make an excellent crop for square foot gardening that one plant can yield five pounds. 


Trellis and combination gardening

Vining cucumbers that require a trellis for support are ideal for square foot gardening where you’ll plant on the south-facing side of it. Because of the design, you can even maximize the space more and use the area underneath to grow other crops like lettuce. Speaking of combining plants, you can also grow tomatoes alongside cucumbers since they make excellent companion plants to each other in a square foot garden.

The greenhouse makes it possible to prevent potential drawbacks when doing combination gardening like the ones mentioned. You don’t have to worry about fluctuating temperatures, inadequate air circulation, or maintenance weaknesses that affect harvesting. However, the emphasis is necessary on the spacing requirements of each crop alongside their preferred environmental conditions. 


Proper Spacing For Cucumbers

Different spacing requirements depend on your plant variety and when you plan to grow cucumbers. It would be best to remember that cucumbers will survive easily if you sow them as seeds directly without transferring them. After all, they have sensitive roots compared to other crops. 


Bushy vs vining cucumbers

It’s also essential to learn about the proper spacing for cucumbers so you could adjust accordingly if you’re not planning on square foot gardening. For starters, you need to consider the variety of cucumber plants that you’re cultivating. You can opt for a bushy variety if you are limited in space, while vining cucumbers will require twice the recommended spacing of a bushy variety.


Spacing for hills, rows, trellising, and containers

If you have bush cucumbers, allocate 3 feet of space, while vining cucumbers should have 6 feet or more. You can also grow them in a pile of soil about 3 inches tall that will receive four seeds until you thin them into two plants later on. On the other hand, allocate 2 inches of space between each seed if you plant in a row and have each row 5 feet apart for trellising later on. 

Remember that cucumbers are the type of crop with sensitive roots, which means sowing them directly is safer than using transplants or seedlings. However, if you’re growing cucumbers in a container, use a 24-inch pot that will contain one cucumber plant. Wherever you’re growing cucumbers, the one factor to remember is that bushy plants will require lesser space. 

The next decision will lie on how much fruit you want and how early you need them. Bush varieties will produce cucumbers first, but having a more prominent space will also mean more cucumbers to harvest in vining varieties. 


Why Is Spacing Important In Cucumbers?

Spacing is vital in cucumbers to prevent problems in growth and diseases. If you fail to plan your spacing both in square foot or traditional gardening, you’ll overcrowd your plants. This will lead to inefficient watering, air circulation, and problems in harvesting. One of the most common diseases that you might also encounter is powdery mildew. 

Because of the spacing, the humidity among plants can encourage the growth of this fungus. You’ll notice the white and powdery growth on your cucumbers’ leaves and stems, causing browning or death. If you’re not using a greenhouse and your area experiences warm days and cold nights alongside high humidity, your cucumbers are at increased risk of fungal infection. 



Cucumbers are easy yet productive crops to grow, especially in an optimal environment such as the greenhouse. But if you have limited space, you’ll be pleased with how many cucumber plants per square foot will fit. You can sow two seeds or have two transplants per square foot, and it’s also possible to do companion gardening with lettuces or tomatoes with proper planning.

Gone are the days you’re limited with the crops you can grow if you have limited space. Nowadays, gardeners and university extensions have discovered techniques to allow everyone to benefit from homegrown plants.
