Best Vegetables to Grow in 5-Gallon Buckets

Here’s a list of vegetables that thrive in deep, confined spaces—offering big rewards from a small footprint.

🍅 1. Tomatoes

Tomatoes are a classic container crop. Their deep roots and vertical growth make them a natural fit for 5-gallon buckets.

Tips:

Choose determinate (bush) varieties for easier maintenance.

Add a tomato cage or stake for support.

Water consistently to prevent cracking or blossom end rot.

🌶 2. Peppers (Bell or Hot)

Whether sweet or spicy, peppers grow beautifully in buckets. They don’t need much space and appreciate warm, contained soil.

Tips:

Use well-draining, rich potting soil.

Provide full sun (6–8 hours daily).

Stake taller varieties to prevent toppling.

🥔 3. Potatoes

Surprised? Potatoes actually thrive in 5-gallon buckets! Their underground growth habit is ideal for vertical container setups.

Tips:

Start with 3–4 inches of soil and add more as the plant grows (“hilling”).

Harvest by simply dumping the bucket!

Ensure multiple drainage holes to prevent rot.

🥕 4. Carrots

Long-rooted veggies like carrots benefit from the depth a 5-gallon bucket provides, especially in loose, well-aerated soil.

Tips:

Use a sandy or fluffy potting mix.

Thin seedlings early to allow room for roots.

Keep the soil evenly moist to prevent splitting.

🧅 5. Onions

Whether you’re growing bulbs or green onions, a bucket is more than deep enough to accommodate their root systems.

Tips:

Use sets or transplants for quicker results.

Space bulbs evenly for good airflow.

Water regularly but avoid soggy soil.

🥒 6. Cucumbers

Cucumbers can yield heavily—even in containers—if supported correctly. Bush varieties work best in small spaces.

Add a small trellis or stake for climbing.

Water deeply and regularly.

Quick Tips for Bucket Gardening Success

To get the most out of your bucket garden, follow these best practices:

🔧 Drainage First

Drill 4–6 holes in the bottom of each bucket to ensure proper drainage. Without it, roots may rot from excess moisture.

🌱 Use Quality Soil

Skip the dirt from your yard. Use a premium potting mix with compost or slow-release fertilizer to support healthy growth.

🪴 Support Your Plants

Install cages, trellises, or stakes early—especially for vining or top-heavy crops like tomatoes and cucumbers.

🌞 Choose the Right Spot

Most veggies need at least 6 hours of sun per day. Move buckets to chase the sun if needed!
