Bartholomew came up with the idea for square foot gardening while working as a retired engineer in the early 1980s. Since then, this practice has grown in popularity among those with limited area in their gardens, particularly those in tiny or backyard plots. It’s a great way to acquire more produce in a less space.

Square foot gardening consists of a 4-by-4-foot garden bed with a depth of 6 to 12 inches and a width of 4 feet. Light-weight and nutrient-rich soil mix fills the bed, which serves as the foundation for the plant’s development.

Square foot gardens promise to produce 100% of their costs, 20% of their space, 10% of their water, 5% of their seed, and 2% of their labor for 100% of their harvest.

Factors to consider while planting on a small area

  • Convert one square foot of nutrient-rich soil amendment in each raised bed into an area of one square foot To make things easier, Mel recommends using wood to divide the square foot.
  • Every square foot should be planted with a distinct type of crop, resulting in different square feet containing plants that are complementary to one another.
  • 16 different vegetables can be grown in a total area of 4×4 square feet.
  • According to Mel, you may cultivate 1, 2, 4, 6, 9, or 16 plants per square foot in a square foot garden, depending on the size of the veggies.

Accessories that may be helpful:

  • Protects young plants from major pests such as squirrels, birds, rats, and mice using a chicken wire cage.
  • Protects the dome supports from adverse weather by covering them in plastic.
  • Climbing plant support trellis.

In a square-foot garden, cucumbers are an excellent summertime delicacy that are easy to grow. They tend to occupy the raised bed’s outer squares near the trellis most of the time. You should look for light feeder plants to accompany cucumbers because they are heavy feeders.

Cucumber Spacing Tips for the Biggest Harvest Yet!

To maximize the vertical space in your trellis, use the vining type of cucumber over the bush variety.

Cubes can be grown in a square foot garden in the following manner:

1. Select the suitable location for square foot garden

Cucumber, along with the majority of its relatives, requires a minimum of eight hours of daily exposure to sunlight. Make sure to pick a spot that’s flat and has good drainage. We don’t really care about the sort of soil in the chosen area because we’ll be growing the plants in a raised soil layer.

A good square foot garden can be built even in inadequate soil provided the other conditions are right.

I usually recommend placing cucumber plants near your home because they require a lot of attention.

2. Build a raised bed of appropriate dimension

The square foot garden bed has an ideal size of 4 square feet by 4 square feet. A king-sized bed is the best option because you can easily go to the center of the bed from any side. With youngsters in tow, a 3×3-foot bed is preferable for garden upkeep.

Garden beds should be between 6 and 12 inches high.

To construct the raised bed, these are the materials needed:

3. Fill your raised garden bed with nutrient-rich soil

Filling the raised garden bed with a nutrient-rich soil mix is the next step after you’ve constructed it.

Soil recommended by Mel Bartholomew has a third of peat moss, one third of vermiculite, and one third of multifunctional compost.

When it comes to improving soil structure and water retention, peat moss is an excellent choice. Coconut coir is an excellent substitute for peat moss if you can’t find it or don’t want to use it.

Byproducts of the coconut processing industry are used to make coconut coir.

There are many benefits to using vermiculite, including improving soil aeration and texture. It is mined from the earth’s surface.

In the soil mix, compost is used as a nutrient source because it’s so versatile. The nutrient is released over time through composting.

Garden and kitchen trash can be used to build your own compost, or you can buy it from a garden supply store.

For raised garden beds, you can also buy soil mix straight from the store.

4. Plant your cucumbers

In square foot gardening, two cucumber plants per square foot is the ideal spacing. It is recommended that the two plants be spaced 6 inches apart so that they can grow properly. Try to keep the plants in the middle while planting. Plant one plant three inches to the right of the center and another three inches to the left of the center to achieve this.

Cucumber plants can be grown in two ways: either by seed or by cuttings.

  • Cucumber seeds can be sown directly in the raised garden bed. Frozen cucumber seedlings are particularly vulnerable to harm. The seed should be sown one week after the last frost date to avoid damaging the seedlings.
  • It’s possible to grow cucumber seeds indoors and then transplant them outside once the final frost date has passed. You’ll be able to harvest a couple days sooner this way.

In the trellis, cucumbers are vine-like plants, and they climb upwards. Cucumbers planted in the raised bed’s southern corner will receive less sunlight than those in the bed’s northern corner.

The easiest way to ensure that all of the plants in the square foot garden get at least six to eight hours of sunlight each day is to place them according to their height.

Plant cucumbers and other vine-producing plants near the trellis that you built on the north side of your garden plot. On the second row, tall plants like tomatoes and okra, as well as medium-sized plants like peppers, bush beans, bush tomatoes, and chilies, are appropriate. It is best to place all of your shorter plants such as lettuce and garlic in the last row near the southern end of your garden.

5. Build the trellis

Cucumbers in a square foot garden need a trellis to support their upward growth. The trellis design for a square foot garden isn’t set in stone. Cucumbers and other vine plants can thrive in any setup that allows them to grow vertically.

Don’t forget to construct the trellis on the bed’s northern side so that all of the plants get the maximum amount of sunlight exposure.

You can use wood, steel, or wire to make the trellis.

Here is a step-by-step guide to building a trellis for a square foot garden with cucumbers:

The following are the necessary supplies:


  • To begin, connect the 4 feet of pipe to the elbow fitting.
  • The trellis will be attached to the side of the square foot garden box, so place the pipe there now.
  • Make a mark on the ground near the garden bed where the elbow fitting corresponds to the point you made on the elbow in the ground.
  • At the designated spot, drive two steel rebar stakes halfway into the earth.
  • It’s time to secure both elbow sockets by attaching the 5 feet steel pipe with a 4 feet top crossbar.
  • Incorporate the 5 feet of pipe into the rebar.
  • The netting should be woven into the framework. The top two corners should be tied first, followed by the rest of the points. It is important to keep the net in the bars tightly.

6. Maintain your garden

Only 2% of the garden’s square footage must be worked in order to get a 100% harvest. This does not relieve you of the responsibility of caring for your plants. However, compared to traditional gardening, the amount of time and work you need to put into your garden is significantly less.


You can’t just hand out a watering schedule and expect it to work for your plants; the quantity your plants need relies on a variety of elements, including the environment where they’re being grown, the type of soil, and more. The watering schedule that works in one location may not work in another.

Watering the plant when the soil is dry is what I suggest. You can tell if your plant is ready for watering simply by sticking your finger in the soil. Forefinger-poke the ground. Because if the soil is dry to an inch deep, you should water your plants immediately.

The best way to tell if your plants are ready to be watered is to perform a finger test. The soil’s moisture content can be determined without the use of expensive equipment.

This method is also useful for keeping track of soil moisture levels and scheduling irrigation times.

The best time to water your plant is early in the morning. During the day, the heat of the sun helps to evaporate the moisture from the leaves. It’s possible that plants can become infected with the fungal illness if water is applied in the evening. Powdery mildew and downy mildew are two of the most common fungal illnesses that affect cucumbers.

Avoid watering the plant’s foliage when watering it from the base.

Weed control:

Raised garden beds benefit from the use of weed barrier material, which keeps weeds at ground level. However, some weed seeds may come from compost or other sources and enter the garden.

In order to remove weeds that are very small, you must be careful not to disrupt the plant’s roots while doing so. Uprooting the huge weed, on the other hand, disrupts the roots of the vegetable plants, therefore it is best to cut it down to the soil’s surface.


Mulching is a must if you want to keep soil moisture levels stable and keep weeds under control. The sun does not degrade the soil when it is covered with mulch. The beneficial bacteria in the soil’s top layer are killed when it is exposed to the sun directly.

Always choose for organic mulch when making your garden mulch selections. In time, the organic mulch degrades and adds to the soil’s organic matter content. Straw, hay, and dried grasses are all common organic mulches.

Pest control:

Pest infestations can be detected by inspecting the field on a regular basis. Large pests like rats and squirrels can be protected by a cage made of chicken wire. Handpick and destroy the adult and egg masses of other small insects from the plant early in the infestation for the sake of other little bugs and insects.

The best and most chemical-free approach of controlling insects is to encourage the growth of the pest’s natural predators. If the pest problem is severe, you should use the pesticide that has been prescribed to you.

In order to maximize yields in a small space, square foot gardening is the ideal method to use. It doesn’t take a lot of time or money to grow vegetables in your own backyard.

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

Two seeds or transplants per square foot spaced 6 inches apart

Cucumber plants need 6 inches of space between each other in the middle of the square if you want them to grow properly. There are numerous advantages to using the square foot gardening method in any greenhouse. Cucumber care is made easier in general by square foot gardening.

Even if you have a smaller space, they will be just as fruitful as a regular garden. Cucumber plants can produce up to three pounds of cucumbers per plant. As a result, if you’re looking to maximize output, two plants should be sufficient to feed a single person.

Cucumbers are a popular crop for square foot gardening because one plant may produce up to five pounds of fruit.

Trellis and combination gardening

The south-facing side of your square foot garden is the best place to plant vine cucumbers that require a trellis. To further maximize the space, you can even grow lettuce in the area below, thanks to the unique design. You may also grow tomatoes and cucumbers together in a square foot garden because they are good companion plants.

Combination gardening, such as the kind described above, would be impossible without the greenhouse. When harvesting, you don’t have to worry about variable temperatures and poor air circulation. Keeping in mind the crop’s optimum environmental conditions and the spacing needs is critical, however.

Proper Spacing For Cucumbers

Depending on the species of plant and the time of year you wish to grow cucumbers, you may need to adjust your planting spacing. You should keep in mind that cucumber seeds can be sown directly without moving them. Compared to other crops, their roots are more delicate.

Bushy vs vining cucumbers

If you’re not going to grow in squares, you’ll need to know how far apart to plant your cucumbers in order to make the necessary adjustments. As a starting point, you’ll want to evaluate the type of cucumbers you’re growing. Vining cucumbers require twice the spacing of bushy cucumbers, so if you’re short on space, go with a bushy variety.

Spacing for hills, rows, trellising, and containers

For bush cucumbers, 3 feet of space is sufficient, while for vine cucumbers, 6 feet or more is required. It’s also possible to grow them in a 3-inch-tall pile of dirt that will hold four seeds until you thin them to two plants. In contrast, if you wish to trellise your plants later, plant them in rows 5 feet apart with 2 inches of spacing between each seed.

Keep in mind that because cucumbers have such delicate roots, planting them directly is the safer option. A 24-inch pot that can hold a single cucumber plant is the best choice for growing cucumbers in a container. Cucumbers need less area when they are bushy, so keep that in mind wherever you plant them.

Once you’ve decided how much fruit you want and when you need it, you’ll have to make another decision. In the beginning, bush kinds will have the most cucumbers to harvest, but vining variety will have more as well.

Why Is Spacing Important In Cucumbers?

Cucumbers need to be spaced apart to avoid growth and disease issues. To avoid overcrowding in both square foot and traditional gardening, you must arrange your spacing in advance. As a result, watering, air circulation, and harvesting will be hampered. Powdery mildew is another prevalent ailment that you may come into.

It is possible that the fungus will spread more readily if there is a high level of dampness between the plants. Your cucumbers’ leaves and stems will become brown or die as a result of the white and powdery development. Cucumbers grown without a greenhouse are more susceptible to fungal infection during periods of warm days and cold nights, both of which are accompanied by high humidity.


Cucumbers are an easy-to-grow crop that yields well when grown in a greenhouse. The number of cucumber plants you can fit per square foot will surprise you, however, if you don’t have much room. Proper planning makes it possible to grow lettuces and tomatoes in companion gardens by sowing two seeds or transplanting two plants per square foot.

If you have a little plot of land, you no longer have to limit yourself to one or two crops. Gardeners and university extensions have developed methods to make cultivated plants accessible to the general public.
