How to Grow a Square Foot Garden
Square foot gardening is an efficient and organized method that allows you to grow a variety of plants in a small space. By dividing your garden into 1-foot sections, you can maximize your yield while minimizing effort and resources.
| Protip: How to Plan Your Square Foot Garden Planning a square foot garden involves several key steps. First, select a sunny location and build a raised bed frame. Divide the bed into square-foot sections using a grid. Choose a variety of crops suited to your climate and growing season. Plant seeds or seedlings in each square based on their space requirements. Regularly water, weed, and monitor for pests. Rotate crops and amend the soil with compost annually to maintain fertility and maximize yields. |
Step 1: Select Spot
Choosing the right spot for your square foot garden is crucial.
Look for a location that receives at least 6-8 hours of sunlight each day, as most vegetables and herbs thrive in full sun. Ensure the spot has good drainage and is easily accessible for watering and maintenance.
Avoid areas with heavy foot traffic or where water tends to pool after rain. If you have pets or small children, consider placing a barrier around your garden to protect it.
Step 2: Prepare Raised Garden Bed
Building a raised garden bed is the foundation of your square foot garden.
Opt for untreated wood, bricks, or cinder blocks to construct the bed, ensuring it’s at least 6-12 inches deep to accommodate root growth.
The ideal size for a square foot garden bed is 4 feet by 4 feet, making it easy to reach every plant without stepping on the soil.
Line the bottom with landscape fabric or cardboard to prevent weeds from encroaching.
Step 3: Grid with Bamboo Stick
Once your raised bed is ready, create a grid using bamboo sticks or string.
Divide the bed into 1-foot by 1-foot sections, securing the grid firmly.
This grid will help you organize your planting and make the most efficient use of space.
Each square foot will host different plants, making it easier to manage and rotate crops.
Step 4: Fill the Bed with Amended Soil
The success of your square foot garden largely depends on the quality of your soil.
Mix together 1/3 vermiculite, 1/3 peat moss, and 1/3 compost to create a rich, well-draining soil blend.
Vermiculite aids in moisture retention and aeration, peat moss improves soil texture and acidity, and compost provides essential nutrients for plant growth.
Fill your raised bed with this soil mixture, leveling it evenly across the grid.
Step 5: Plant Favourite Veggies
Now comes the fun part—choosing and planting your favorite vegetables, herbs, and flowers.
You can plant either seeds or seedlings, depending on your preference and the growing season.
Some popular options for square foot gardening include tomatoes, eggplants, carrots, beetroots, lettuce, broccoli, asparagus, mint, basil, pansies, parsley, parsnips, petunias, potatoes, radishes (large varieties), salvia, strawberries, cabbage, cauliflower, okra, oregano, peppers, sweet potatoes, kale, fennel, melons, and pumpkins.
How Many Plants Can Be Sowed Per 1 Square Foot and the Distance Between the Plants
Square foot gardening optimizes the use of space by planting a certain number of plants per square foot based on their size and growth requirements. Here’s a detailed guide for various popular plants:
Tomatoes: Tomatoes are large plants that require support and plenty of space. Plant 1 tomato per square foot, and ensure it has a sturdy cage or stake to grow on.

Basil: Basil is a versatile herb that thrives in close quarters. Plant 4 basil plants per square foot, spacing them about 6 inches apart.
Pansies: Pansies are small flowers that add color to your garden. Plant 9 pansies per square foot, spacing them evenly.
Parsley: Parsley grows well with moderate spacing. Plant 4 parsley plants per square foot, spacing them about 6 inches apart.
Parsnips: Like carrots, parsnips need space for their roots. Plant 9 parsnips per square foot, with about 4 inches between each plant.
Petunias: Petunias can add vibrant blooms to your garden. Plant 4 petunias per square foot, spacing them about 6 inches apart.
Potatoes: Potatoes require more room underground. Plant 1 potato plant per square foot, ensuring it has enough soil depth to grow tubers.
Radishes (large varieties): Large radishes need more space than smaller varieties. Plant 9 radishes per square foot, spacing them about 4 inches apart.
Salvia: Salvia plants need moderate spacing. Plant 1 salvia per square foot to allow for their bushy growth.
Strawberries: Strawberries spread via runners. Plant 4 strawberry plants per square foot, spacing them about 6 inches apart.
Cabbage: Cabbage plants are large and require significant space. Plant 1 cabbage per square foot.
Cauliflower: Similar to cabbage, cauliflower needs room to develop its head. Plant 1 cauliflower per square foot.
Okra: Okra plants are tall and need support. Plant 1 okra per square foot, ensuring it has enough space to grow upwards.
Oregano: Oregano is a spreading herb. Plant 4 oregano plants per square foot, spacing them about 6 inches apart.
Peppers: Peppers can be planted closely. Plant 1 pepper per square foot, providing a stake or cage for support.
Sweet Potatoes: Sweet potatoes spread underground. Plant 1 sweet potato slip per square foot, ensuring deep, loose soil.
Kale: Kale can be planted fairly close together. Plant 4 kale plants per square foot, spacing them about 6 inches apart.
Fennel: Fennel requires more space for its bulb to develop. Plant 1 fennel per square foot.
Melons: Melons are vining plants that need space to spread. Plant 1 melon per square foot and train the vines to grow vertically with support.
Pumpkins: Pumpkins need significant space. Plant 1 pumpkin per square foot, allowing the vines to sprawl outside the square foot area.
By following these guidelines, you can maximize the efficiency of your square foot garden, ensuring each plant has the space it needs to thrive while making the most of your available growing area.
Step 6: Maintain
Regular maintenance is key to a thriving square foot garden. This includes:
Watering: Keep the soil consistently moist but not waterlogged. Water in the early morning to reduce evaporation.
