What Is Square Foot Gardening?

TV host Mel Bartholomew created square-foot gardening in the 1970s. He developed the method as a way to garden in small spaces.

The key to square-foot gardening is to divide your growing area into small squares. Each square is one foot wide and one foot deep.

Square foot gardening is a type of gardening that allows you to grow a lot of plants in a small area.

It is an excellent way grow food if you have limited space or want to maximize your yield in a small garden.

Square-foot gardening works by dividing your growing area into square feet and then planting one type of plant in each square.

This division allows you to space your plants evenly and to know precisely how many plants you can grow in a given area.

You can grow various vegetables, herbs, and flowers in each square. The density determines how many of each item you will plant in a square.

For example, you can grow nine garlic plants in one square. But, you would only produce one tomato plant per square.

This process works well because it allows you to control your plants’ spacing better and ensure that each plant has room to grow.

It also helps you to avoid overcrowding, which can lead to diseases and pests.

Square-foot gardening increases yields by allowing you to grow more plants in a smaller space. It also helps you to use your area more efficiently and to get the most out of your garden.

What Is Arugula?

Arugula is a leafy green vegetable from the Brassica family. This family also includes vegetables like kale, collards, and Brussels sprouts.

Arugula has a milder peppery flavor than some other greens in this family.

Arugula is often used in salads and is a good source of vitamins A and C. It is an excellent addition to salads, sandwiches, and pizzas.

You can also cook arugula, but it’s best when used fresh.

Arugula is a cool weather crop you can plant in the spring or fall. It grows best in full sun but can also tolerate some shade. Just be sure to keep it watered, and it will do well.

Arugula is relatively easy to grow and does not require much care. It is drought-tolerant and can even handle some frost.

Arugula is a fast-growing crop and can be harvested just 4-6 weeks after planting.

It can be harvested continuously throughout the growing season, making it an excellent crop for gardeners who want a steady supply of fresh greens.

Once it starts to bolt or produce flowers, the arugula will become too bitter to eat. You can still harvest the seeds from the flowers and use them to grow more arugula next season.

How To Grow Arugula in a Square Foot Garden

You can plant up to four arugulas per square foot. Do not them go to seed; they will grow everywhere and be challenging to control. Once your arugulas are ready to harvest, cut the leaves about one inch above the soil.

Start with seeds or transplants to grow arugula in your square-foot garden. Plant the seeds or transplants in the center of each square. Arugula does not need much space to grow so you can plant them close together.

If growing arugula from seed, start the seeds indoors about four weeks before the last frost date. Plant the seeds in a damp potting mix and keep them warm.

The seeds will germinate in about ten days.

Transplant the seedlings into your square-foot garden when they are about four inches tall. Space the plants about six inches apart. Arugula will mature in about 40 days.

Arugula is ready to pick when the leaves are about four inches long. Cut the leaves off at the base of the plant.

Here is some advice on growing arugula in a square-foot garden:

  1. Choose a sunny spot in your garden for your arugula plants. Arugula likes full sun but can also tolerate some shade.
  2. Use a sharp knife or garden shears to cut the arugula plants back to about 6 inches tall when they start to flower. This process will encourage the plants to produce more leaves and prevent them from going to seed.
  3. Harvest the arugula leaves when they are about 4-6 inches long. You can harvest arugula continuously throughout the growing season.
  4. Store the arugula leaves in a plastic bag in the refrigerator for up to 2 weeks.
  5. Rinse the arugula leaves before use, and chop or tear them into bite-sized pieces.

Why Does Square Foot Gardening Use a Grid?

The plants are usually in long rows if you’ve seen a traditional garden. Square foot gardening uses a grid system to plant its crops.

This design may seem like a lot of extra work, but there are reasons for doing it this way.

For one thing, it makes weeding a lot easier. When the plants are in rows, it’s easy for weeds to get mixed in and grow unnoticed. A grid system makes the weeds much easier to spot and pull.

Another advantage of using a grid is that it makes watering more efficient.

When the water can flow evenly between the rows of plants, each plant gets the same amount of water. This system prevents drought conditions and ensures the plants get the moisture they need.

Finally, a grid system makes it easier to keep track of what’s growing where. When you have a traditional garden, it can be hard to remember which plant is which.

Each plant has its own space with a grid system, so you always know exactly where it is.

How To Water a Square Foot Garden

Hand watering and drip irrigation are the best methods for watering a square-foot garden.

Hand watering is the simplest method and requires a hose and a sprinkler head.

This method is best for small gardens or if you want to water your plants more slowly so they can absorb the water better.

Drip irrigation is more complex, but it’s worth it because it saves a lot of water. Drip irrigation uses a system of pipes to match your garden grid.

Drip heads will slowly water each plant individually. This method is best for more extensive gardens or if you want to save water.

Regardless of your chosen method, water your plants deeply and regularly. Deep watering means getting the water to the plant’s roots where it can do its best.

Regular watering means not letting the soil dry out ultimately between waterings, which will help your plants stay healthy and prevent them from getting stressed.

What Kind of Soil Should You Use in a Square Foot Garden?

A good mix is equal parts vermiculite, compost, and coconut coir. Vermiculite is a lightweight material that helps aerate the soil and retain water.

Compost is rich in nutrients and helps improve drainage, and coconut coir is made from coconut husks and helps improve drainage while retaining moisture.

This mix will give your plants the nutrients they need to grow healthy and strong. It will also help the soil hold onto water so your plants don’t dry out.

Common Square Foot Gardening Mistakes

It’s easy to make mistakes when trying out new techniques or hobbies. Here are a few common square-foot gardening mistakes people may encounter.

Not Measuring Grids

You’ll likely have wonky, uneven rows if you try to wing it and create your gridlines without measuring. This disorganized system will make it harder to plant and care for your garden.

Planting Near Fences

Planting against a fence will make weeding extremely difficult when plants are fully grown and difficult to access the back of your garden.

Incorrect Location

Pick a location that receives sun and shade for your square foot garden throughout the day, which will ensure that your plants get the sunlight they need to grow but will also have cover from the harsh midday sun.

Not Starting Small

You may be excited to start your square-foot garden, but it’s essential to start small. You can add more later, but it’s much harder to reduce the size of your garden once you have planted.

If you start too large, you may be overwhelmed by weeding, watering, and maintenance. Stick to a small area to start, and you can always expand later.

Not Caring for Your Soil

Soil is the foundation of a garden, so it’s important to take care of it.

Care means adding compost and other amendments to keep it healthy. It also means avoiding chemicals that can harm the microbes in your soil.

Not Planning Your Garden

You may be in a rush to start planting, but it’s important to plan your garden first. Planning includes drawing a map of where you want everything to go and what you want to grow.

Planning will save you time and frustration later. You’ll be less likely to make mistakes, and you’ll be able to take advantage of your space better.

Not Watering Properly

Water is essential for plant growth, but too much or too little water can be detrimental. Water your plants early so they have time to dry out before nightfall.

Water the base of the plant, not from above, to help prevent disease and reduce evaporation. And make sure to check your soil before watering to see if it needs water.

Not Fertilizing

Fertilizer helps plants get the nutrients they need to grow. But using too much fertilizer can harm your plants and pollute the environment.

Only fertilize when your plants need it. A soil test can tell you if nutrients are missing from your soil. And be sure to follow the directions on the fertilizer package.

Not Inspecting Your Plants Regularly

Inspect your plants regularly for pests or diseases. This way, you can catch problems early and take care of them before they get out of hand.

Check the undersides of leaves for pests, look for brown spots or wilting leaves, and pull up any plants that seem to be suffering.

Not Pruning

Pruning is vital for both fruit and vegetable plants. It helps promote growth and ensures that your plants produce the best possible fruits and vegetables.

For most plants, you should prune in the late winter or early spring because this will help the plant put its energy into new growth instead of fruit production.

Not Composting

Composting is a great way to recycle organic waste and improve your soil. It’s easy to do, and it’s a great way to reduce your impact on the environment.

Composting adds organic matter (like food scraps or leaves) to your soil, provides nutrients for your plants, and helps improve the structure of your soil.

Not Using Pest Control Methods

If you have pests in your garden, it’s important to take care of them immediately. Otherwise, they could destroy your plants.

There are many organic pest control methods available. You can use neem oil, diatomaceous earth, or beneficial insects.
