How Many Cucumber Plants Per Square Foot

It’s essential to know how many cucumber plants per square foot is appropriate, which is two. Proper spacing, regardless of the crop, is crucial for the success of your garden and farm. Cucumbers also allow gardeners to use square foot gardening to maximize their space even more without affecting the plants’ growth and health.

You can do square foot gardening of healthy greens and cucumbers in the greenhouse. This way, you can ensure that you will provide the ideal environment for the vegetables. You can choose between slicing and pickling cucumbers, and both will thrive well in an indoor environment and square foot gardening.

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.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
