Square Foot Gardening for Beginners: What is Square Foot Gardening

Before we go into the specifics of growing tomatoes, let’s establish a foundational understanding of what square foot gardening is. 

Square foot gardening was pioneered by Mel Bartholomew who revolutionized traditional gardening by condensing planting spaces into organized, easy-to-manage grids. Its core principles emphasize efficient space utilization, minimal maintenance, and bountiful harvests. Now, imagine applying these principles to the vibrant world of tomatoes – one of the most beloved and versatile crops in home gardening.

The principles of this concept are as follows:

1. Grid System: At the core of square foot gardening is the use of a grid system. The growing area is divided into one-foot-by-one-foot squares, and each square is dedicated to a particular crop. This grid not only provides a structured layout but also simplifies planning and maintenance.

2. Intensive Planting: Unlike traditional gardening, which often spaces plants far apart, square foot gardening promotes intensive planting. By maximizing the number of plants within each square foot, the garden becomes a lush and productive space. Intensive planting also helps to reduce weed growth by creating a dense canopy. It can provide cover for plants that don’t need as much sun during the day, and need a break at the hottest points of the day.

3. Companion Planting: Square foot gardening encourages the practice of companion planting, where compatible plants are grown together to promote mutual benefits. This includes pest control, improved nutrient absorption, and efficient space utilization. For example, basil and tomato plants are perfect companions in the garden.

4. Raised Beds: Many square foot gardens utilize raised beds to create defined growing areas. Raised beds offer better drainage, warmer soil temperatures, and ease of access for planting, weeding, and harvesting.

5. Soil Mix: The soil mix in square foot gardening is a critical component. It typically consists of a balanced blend of peat moss, vermiculite, and compost. This mix provides a light, well-draining medium that supports healthy plant growth.

Square Foot Gardening vs Traditional Gardening Methods

To further understand square foot gardening, let’s see how it compares up against traditional gardening methods.

  • The first comparison between traditional methods and square foot gardening is space utilization. In traditional gardening, plants are often spaced apart to accommodate their mature size, leading to significant open spaces between rows. In contrast, square foot gardening optimizes every inch of available space, resulting in a more efficient use of the garden area.
  • There’s a reduction in maintenance. Traditional gardens can be labor-intensive, requiring extensive weeding and ongoing maintenance. Square foot gardening minimizes these tasks by using intensive planting to naturally suppress weeds and employing a well-defined grid system for easy organization.
  • Square foot gardening tends to be more efficient with water use. Traditional gardens may require more water due to the open spaces and larger distances between plants. Square foot gardening, with its close plant spacing, reduces water wastage and promotes efficient irrigation.
  • It can be more accessible to people of all ages, especially if raised beds are used. Square foot gardening is particularly well-suited for those with limited mobility or small gardening spaces. The raised beds and organized grid make it easier for individuals to reach and tend to their plants without the need for extensive bending or stretching.

In essence, square foot gardening reimagines the traditional approach to gardening, emphasizing efficiency, productivity, and accessibility, making it an appealing and practical choice for gardeners of all experience levels.

Growing Cucumbers Using the Square Gardening Method

Cucumbers are a garden favorite and what’s great is that they’re super easy to grow. They’re definitely one of the plants we put in the garden every single year. There are so many varieties to choose from. So one of the things to keep in mind when growing cucumbers is what are you going to be using them for? Pickling? Salads and sandwiches? The second tip – which varieties grow the best in your growing zone? If you’re unsure what your growing zone is, check out the link below where I talk all about it.

Cucumber Plant Basics

When planning to grow cucumbers, understanding their specific growth requirements will ensure a successful harvest. These vigorous plants need adequate spacing, nutrient-rich soil, and consistent watering.

Optimal Growing Conditions

Cucumbers thrive in warm weather and require a minimum temperature of 65°F to germinate effectively. They perform best when daytime temperatures are between 70°F and 85°F. You should plant cucumbers in a location that receives full sunlight for at least 6-8 hours daily to promote healthy growth and maximum yield.

Soil Requirements

Your cucumbers will need well-draining soil with a pH level ranging between 6.0 and 7.0. The soil should be rich in organic matter to provide the necessary nutrients for growth. Amend your garden soil with compost or well-rotted manure before planting to boost its fertility.

Watering Practices

Cucumbers require consistent moisture for optimal growth, so aim to provide your plants with about 1 inch of water per week. Ensure that you water deeply to encourage strong root development. Whenever possible, use drip irrigation or soaker hoses to water at the soil level, which helps prevent leaf diseases by keeping the foliage dry.

Space Management

Maximizing the yield of your cucumber plants begins with understanding and implementing effective space management. Here’s how you can optimize space in your garden for cucumbers:

Spacing Recommendations

There are both bush and vining variety plants. Bush varieties aren’t what they seem. They have shorter vines in comparison to vining varieties, and thus are more compact. Bush cucumbers are great for small gardens and can still be trellised. Vining varieties need a lot of space, but it’s totally possible to keep them more tamed by trellising. Otherwise they sprawl all along the ground.

Below are spacing recommendations:

Bush Varieties: For bush varieties of cucumbers, plant them about 12 to 18 inches apart, with rows 3 to 4 feet apart to achieve a higher plant density. 

Vining Varieties: If you’re growing vining cucumbers, space plants 10-12 inches apart within rows, and keep rows 18-24 inches apart.

As a general rule of thumb, I wouldn’t plant more than one cucumber plant per square foot. Although you’ll see sites suggest that it’s totally ok to plant two plants per square foot, this does not seem like a good idea. Cucumbers in general, whether they are bush or vining varieties, get pretty large and need space. By planting them too close together, it’ll cause crowding and open a can of worms with diseases and pests.

Cucumber Planting Techniques and Tips

When it’s time to plant your cucumbers, whether you decide to grab some seedlings or sow seeds, here are a few considerations:

Soil Temperatures

Before you run out to plant your seedlings or sow seeds, check the temperatures. Cucumbers don’t like the cold and soil temperatures should be at least 65 degrees Fahrenheit. When it’s time to start planting, I always check two weeks in advance to make sure there’s no threat of frost.

Vertical Training

By training cucumber plants to grow vertically on trellises, you save space, improve air circulation, and simplify harvesting. In my opinion, this is the best way to grow cucumbers because it gets them off the ground and promotes better air circulation. This approach reduces the chances of infestations, disease, and other issues.

Group Planting

When planting cucumbers in groups rather than rows, position the seeds in clusters of 3, with an 18-inch gap between each group from all directions, accommodating easy access and maintenance.

Plant in the Morning

The morning is the coolest part of the day and is the best time to plant, water, apply treatments, and to beat the heat of the day. Planting during the coolest part of the day helps to reduce transplant stress or sow seeds. The afternoon is going to be the hottest part of the day and therefore cause more stress on the plant. Plus if you’re watering or applying treatments during this time of the day, you’ll most likely burn your plants. It’s very difficult for plants to recover once they’ve been sun scaled (sun burned).

By following these specific spacing recommendations and planting techniques, you can manage your garden space efficiently to cultivate healthy cucumber plants and increase overall yield.

Pruning Cucumber Plants

Keep an eye on your cucumber plants. They can have a tendency to get out of control, which can be counterproductive for things like pollination. Pruning the cucumber plants will not only give energy back to the plants, but allow pollinators to find the flowers.

Yield Optimization

To maximize your cucumber yield per square foot, you need to focus on nutrient management, effective pest control, and proper pruning methods.

Nutrient Management

Your cucumber plants require a balanced diet of nutrients. An adequate supply of nitrogen, phosphorus, and potassium is essential, with a recommended ratio of 1-2-2 (N-P-K). Apply a complete fertilizer at planting time, followed by a nitrogen-rich fertilizer during peak vine growth. The application rate is guided by a simple principle: too little will stunt growth, while too much can harm the plant or the environment. Apply lightly since cucumber plants aren’t heavy feeders.

Pest Control

Vigilant pest control contributes to a healthy cucumber crop. Common cucumber pests include cucumber beetles and aphids, which can be managed using neem oil, for example. Practice crop rotation and remove garden debris to prevent the overwintering of pests. Employing row covers until flowering can also protect your cucumbers from early pest damage.

Pruning Methods

Pruning enhances air circulation and light penetration, key factors in increased yields, as well as reduces disease and pests. For optimal results:

  • Prune lateral shoots up to the 5th leaf node.
  • Remove any shoots growing from the base of the plant.

Limiting the number of fruits per plant can also lead to larger and better-quality cucumbers. By focusing on these pruning methods, you are directing your plant’s energy toward the growth and maturation of the existing fruit.

Harvesting: When are Cucumbers Ready to Pick

The most ideal time of day to harvest cucumbers is in the morning. This helps reduce stress on the plant. You’ll want to look at the skin, test the firmness of the fruit, its length, and shape. Cucumber should have a cylindrical shape and shouldn’t have any narrowing towards its end. It should be an easy taper to a rounded point. Its skin should be a shiny green color. If the fruit has been laying on the ground, you may notice a lighter color that was on the ground. To prevent this from happening, consider trellising. The fruit should also be firm. It shouldn’t be soft at all. Lastly, it should be at least 6 to 8 inches in length. This will vary by the variety that you plant. So always check the plant tag or seed packet for specifics.
