Nothing quite like the satisfaction of eating a meal you’ve grown yourself. Homegrown produce tastes better, whether ripe, juicy tomato still warm from the sun or a freshly-picked ear of corn. And I love nothing more than spending time in my vegetable garden.

I love getting my hands dirty as I plant seeds and pull up weeds. I love the way the smell of fresh-cut herbs fills the air. And I love the sense of accomplishment I feel when I see my hard work pay off. I can’t wait to start my garden every year, and I’m reminded of why I love it so much. So if you’re looking for a hobby that’s both rewarding and delicious, give gardening a try. You might just find that you have a green thumb, after all.

How Big Should My Vegetable Garden Be?

If you are thinking about starting a vegetable garden, you may wonder how big it should be. The answer is not 100 square feet per person. Every family’s needs differ, and so do plants. You may also be considering planting your garden in a container. To find the right amount of space for your garden, calculate the square footage required for your desired vegetable crops. Plan your garden on graph paper to help determine the number of plants you need and what they should grow.

How Big Should My Vegetable Garden Be?

Start Small

If you are new to gardening and want to begin with small-scale vegetable gardens, start by picking a location for your new garden. A small area in your yard that receives at least six hours of sunlight per day is perfect.

Vegetables require a lot of sun, so select a location with no trees. Measure the space and sketch out your garden design. You can always add more plants later.

You can even start a vegetable garden on your rooftop. According to Andrea Bellamy’s book Small-Space Vegetable Gardens, your rooftop, alleyway, front porch, or fire escape are all viable locations for a garden.

Careful planning and using what you have will ensure success. In the end, your garden will yield delicious and healthy vegetables. But how do you go about making the most of limited space?

Calculate the Square-Footage Needed for A Healthy Vegetable Garden

Knowing how many seedlings or plants you need to buy is crucial when starting a vegetable garden. Certain vegetables require specific spacing. You can also calculate the soil enrichment you need, often measured in pounds per hundred square feet of space.

Mulch coverage should be calculated in depth per square foot, and knowing how to calculate the square footage needed for a healthy garden is crucial to ensure you are not overspending.

To calculate the square footage needed for a vegetable garden, start by determining how many vegetables you and your family eat weekly.

Generally speaking, one inch per square foot is sufficient for vegetable plants. You will need about nine gallons of water per week for SFG. For fruiting vegetables, this number will increase to 2 inches per square foot. Then, choose your favorite vegetable and determine the best spacing requirements for it.

Plant Vegetables in Containers

Vegetable gardens vary in size. For a family of four, a 40-foot row should be enough. Beans and squash, on the other hand, require a smaller plot. For a family of four, a thirty-foot row is sufficient.

On the other hand, broccoli should not be grown in a large space. Broccoli is harvested in one go and needs to be preserved.

To determine the right size of your vegetable garden, you must plan your layout. Plan your beds by following the recommended spacings for each crop. Generally, rows should be 18 inches apart. For intensive cropping, plant two to three rows, one each way, with space for footpaths.

Make sure to leave enough room between each bed to reach across the beds without compacting the soil. Then, determine the planting time and date of each crop.

Plan Your Garden on Graph Paper

Graph paper is a simple and effective way to map your garden. The grids are based on a standard scale of one inch of graph paper to eight feet of garden space. To plan your garden, measure in all directions. While there is no rule that your garden should be square, a circular or curved shape can be just as effective. You can use this scale to plan different layouts for your vegetable garden.

Graph paper can also be a fun tool when planning your garden. Graph paper allows you to draw out your garden space in an easy-to-read way, and you can use colored markers and pens to add your personal touch. Add more graph pages if you need to, and use extra graph pages to make trees and records of your growth. A garden planner can help you visualize your garden space and determine the best arrangement of plants.

Water Your Garden

There are several ways to water your vegetable garden, each of which requires a slightly different method. The first method, surface watering, encourages plant roots to grow close to the surface rather than extending deep into the soil.

This method, while effective, can leave plants depending on rainfall and regular watering to stay alive. However, the second method, known as deep watering, promotes more profound root growth and makes plants more resilient to droughts and other environmental stresses.

Ideally, vegetable gardeners should water their gardens two inches per week.

This amount of water varies based on your climate, growing conditions, and other factors. To avoid problems with evaporation and cracked fruit, water your vegetable garden first thing in the morning. Morning irrigation is best because the soil is more excellent early in the day. This way, less water evaporates, and the plants don’t suffer. But even when it is cool outside, you must remember to water your vegetable garden.

No matter how you water your garden, ensure the water soaks evenly into the soil. The best way to know if your garden is getting enough water is to check the soil’s moisture level with a finger. If the top two inches of soil are dry, it’s time to water.

Wet leaves can also encourage fungal diseases, so it’s essential to water the roots and not the leaves. Use a soaker hose or drip irrigation to water your vegetable garden. These irrigation systems direct water to the roots, reducing leaf wetness and saving water.

Mulching Your Garden

Mulching is an excellent way to conserve water and keep your garden healthy. Mulch is a layer of material, such as wood chips, straw, or leaves, placed over the soil to protect it.

Mulching helps the soil retain moisture and keeps weeds from growing. It also adds nutrients to the soil as it breaks down.

To mulch, your vegetable garden spread a two to four-inch layer of mulch over the soil around your plants. Be sure to pull the mulch back six inches from the base of each plant so that the stems are not in direct contact with the mulch. Reapply mulch every few months as needed.

Composting Your Garden

Composting is an excellent way to recycle household and garden waste and create nutrient-rich soil for your vegetable garden.

Compost comprises decomposing organic matter, such as food scraps, leaves, and grass clippings. Composting accelerates the decomposition of these materials by providing the ideal conditions for microorganisms to break down the organic matter.

To start a compost pile, choose an area in your yard that receives some sun but is not in direct sunlight. The ideal location for a compost pile is close to a water source, so you can easily water it as needed.

Begin by layering four to six inches of carbon-rich materials, such as dead leaves, straw, or wood chips, on the ground. Then add four to six inches of nitrogen-rich materials, such as grass clippings, food scraps, or coffee grounds. Alternate layers of carbon and nitrogen materials until your compost pile is three to four feet high.

Water your compost pile whenever the top layer begins to look dry. The compost pile should be moist but not soggy. too much water will slow down the decomposition process.

Turn your compost pile every few weeks to aerate it and speed up decomposition. You will know your compost is ready to use when it is dark brown and has a crumbly texture.

Add compost to your vegetable garden before planting, mix it into the top six inches of soil, and water it well. You can also add compost to existing plants by spreading it around the base of each plant and gently incorporating it into the top layer of soil.

Compost can also be used as mulch to help retain moisture in the soil and suppress weed growth.


Vegetable gardens can vary significantly depending on the available space and how many vegetables you want to grow. The average vegetable garden is about 10×10 feet, but there is no set rule for how big your garden should be. Ultimately, the size of your garden should be based on your needs and preferences.

If you are a beginner gardener or are limited on space, you may want to start with a small garden. You can continually expand your garden as you gain experience and confidence.

Remember to consider your plants’ needs when deciding on the size of your garden. Some vegetables, such as tomatoes, cucumbers, and squash, need ample growing space. Others, like lettuce and radishes, can be grown more closely together.

It is also essential to consider how much time you are willing to devote to your garden. A larger garden will require more time and effort to care for than a smaller one.

Following these guidelines can determine the ideal size for your vegetable garden.
