Bok choy is a perfect addition to any square foot garden. This leafy green vegetable grows quickly and doesn’t take up much space, making it ideal for small gardens. You can grow 4-9 bok choy plants in a single square foot, depending on the variety.
Square foot gardening is a simple method that divides garden beds into 1-foot squares. This approach works well for bok choy, also known as Chinese cabbage. It allows for efficient use of space and makes planning and managing your garden easy.
Prepare a raised bed with rich, well-draining soil to start growing bok choy in your square foot garden. Plant seeds or seedlings about 1 inch apart. Water regularly and fertilize as needed. Harvest when the plants reach 12-15 inches tall by cutting them above the soil line.
Planning Your Square Foot Garden
A well-planned square foot garden maximizes space and yield for growing bok choy. Good planning involves understanding the method, picking a spot, and setting up the bed correctly.
Understanding Square Foot Gardening
Square foot gardening splits a small area into 1-foot squares. This method works great for bok choy, saving space and making planting easy.
A typical square foot garden is 4 feet by 4 feet, which is easy to reach across. Larger 4 feet by 8 feet beds also work well.
For bok choy, plant 9 to 16 plants per square foot, spaced evenly. This gives each plant room to grow without crowding.
Mark squares using a grid. Bamboo stakes or string work well. This helps keep the garden tidy and organized.
Choosing the Right Location
Pick a spot with the right amount of sun for bok choy. It needs 4-6 hours of sunlight daily.
Some afternoon shade is good in hot areas. This keeps bok choy from bolting too fast.
Look for level ground. This makes watering easier.
Choose a spot near a water source. Bok choy needs steady moisture.
Avoid areas with strong winds. Wind can dry out and damage plants.
Setting Up the Garden Bed
Build a raised bed for your square foot garden. This improves drainage and soil quality.
Make the bed 6-8 inches deep. Bok choy has shallow roots.
Fill the bed with rich, well-draining soil. Mix in compost for added nutrients.
Test the soil pH. Bok choy likes a pH between 6.0 and 7.5.
Add a layer of mulch on top. This helps keep moisture in the soil.
Make sure the bed edges are sturdy. This keeps soil from washing away.

Soil and Compost in Square Foot Gardening
Good soil and compost are key for growing bok choy in a square foot garden. The right mix gives plants the nutrients they need to thrive.
Soil Requirements for Bok Choy
Bok choy needs well-draining soil rich in organic matter. The ideal pH range is 6.0 to 7.5. Test your soil and adjust if needed.
A loamy soil texture works best. It holds moisture but doesn’t get waterlogged. If your soil is too heavy, mix in sand, or add clay if it’s too light.
Raised beds are great for square foot gardens. They let you control the soil mix. Fill them with a blend of:
- 1/3 compost
- 1/3 peat moss
- 1/3 vermiculite
This mix drains well and holds nutrients. It gives bok choy roots room to grow.
Using Compost for Nutrients
Compost is vital for healthy bok choy. It adds organic matter and feeds soil microbes, breaking down plant roots’ nutrients.
Make compost from:
- Yard waste
- Kitchen scraps
- Leaves
- Grass clippings
Mix it into your soil before planting. Add a 2-inch layer on top too. This feeds plants as it breaks down.
Leaf mold is another great addition. It’s made from decomposed leaves. It improves soil structure and holds water well.
Refresh your square foot garden each season. Add new compost to replace nutrients. This keeps soil healthy for future bok choy crops.

Planting Bok Choy
Planting bok choy is easy and rewarding. This cool-season vegetable grows well in square-foot gardens with the right timing and techniques.
When to Plant Bok Choy
Plant bok choy in early spring or late summer. It grows best in cool weather between 55-75°F. Start seeds indoors 4-6 weeks before the last spring frost. For a fall crop, sow seeds directly outdoors 6-8 weeks before the first fall frost.
Bok choy can bolt in hot weather. Avoid planting in summer unless you live in a cool climate. In warmer areas, use shade cloth to keep plants cool.
Sowing Bok Choy Seeds
Sow bok choy seeds 1/4 to 1/2 inch deep. Space seeds 1 inch apart in rows 18-24 inches apart. For square foot gardens, plant 9-16 seeds per square foot.
Keep soil moist but not waterlogged. Seeds usually germinate in 4-8 days at 70-75°F. Thin seedlings to 4-6 inches apart when they reach 2-3 inches tall.
Use row covers to protect young plants from pests and frost.
Transplanting Seedlings
Transplant bok choy seedlings when they have 4-5 true leaves, usually 3-4 weeks after germination. Harden off seedlings by gradually exposing them to outdoor conditions over 7-10 days.
Dig holes slightly larger than the root ball. Space plants 6-12 inches apart, depending on the variety. For square foot gardens, plant 4-9 per square.
Water deeply after transplanting. Add a layer of mulch to retain moisture and suppress weeds. Protect young plants from strong winds and hot sun as they adjust to their new home.

Watering and Mulching
Proper watering and mulching are key to growing healthy bok choy in a square foot garden. These practices help maintain ideal soil moisture and temperature for optimal growth.
Watering Guidelines
Bok choy needs consistent moisture to thrive. Water the plants deeply and regularly, aiming for about 1 inch of water per week. Check soil moisture by sticking your finger into the soil. If it feels dry 1 inch below the surface, it’s time to water.
Use a soaker hose or drip irrigation system to water at the base of plants. This keeps leaves dry and helps prevent diseases. Water early in the day to allow foliage to dry before nightfall.
A moisture meter can help you monitor soil moisture levels accurately. Aim to keep the soil moist but not waterlogged, as overwatering can lead to root rot.
Benefits of Mulching
Mulching is a great way to retain soil moisture and regulate temperature for bok choy. Apply a 2-3 inch layer of organic mulch around plants, keeping it away from stems.
Straw, shredded leaves, or wood chips work well as mulch for bok choy. Mulch helps:
- Retain soil moisture
- Suppress weeds
- Regulate soil temperature
- Add nutrients as it breaks down
Reapply mulch as needed throughout the growing season. This helps maintain consistent soil moisture and temperature, creating ideal conditions for bok choy growth.

Nutrients and Fertilizing
Bok choy needs the right nutrients to grow well in a square foot garden. Proper fertilizing helps plants thrive and produce tasty leaves.
Essential Nutrients for Bok Choy
Bok choy requires several key nutrients to grow strong and healthy. Nitrogen is crucial for leaf growth and green color. Phosphorus helps roots develop. Potassium boosts overall plant health.
Calcium prevents tip burn on leaves, magnesium aids in photosynthesis, and iron is needed for chlorophyll production. A balanced fertilizer with these nutrients works well for bok choy.
Organic matter in the soil also provides nutrients. Compost or well-rotted manure can improve soil fertility. These natural sources release nutrients slowly over time.
Fertilizing Square Foot Gardens
In square foot gardens, fertilizing bok choy is simple but important. Start with rich soil full of organic matter. Add a balanced fertilizer before planting.
Mix in 6-8 cups of 10-10-10 fertilizer per 100 square feet. This gives plants a good start. Water the soil after adding fertilizer to help it spread.
During the growing season, feed plants every 3-4 weeks. Use a liquid fertilizer high in nitrogen. This keeps leaves growing strong. Be careful not to over-fertilize, as this can harm plants.
For organic gardens, use fish emulsion or compost tea. These natural options provide nutrients without chemicals. Apply them every 2 weeks for best results.
