Cost-effective: Five-gallon buckets are inexpensive or even free from bakeries, restaurants, or hardware stores.
-
Space-saving: Ideal for patios, balconies, and rooftops.
-
Customizable: You control soil type, drainage, and watering frequency.
-
Pest control: Elevating plants in buckets can help avoid certain soil-borne pests.
As long as you drill adequate drainage holes and use a well-draining soil mix, you can grow a surprising number of vegetables in these simple containers.
Best Vegetables to Grow in Buckets
The following vegetables are well-suited for bucket gardening. Each section explains why it thrives in a container, how to grow it successfully, and any special considerations for yield, size, or support.
1. Tomatoes
Tomatoes are a bucket gardening favorite. Compact and determinate (bush) varieties do especially well in containers.
Bucket size: Minimum 5-gallon
Support: Use a cage or stake
Soil: Rich, well-draining soil with compost
Watering: Daily in hot weather
Tips: Choose determinate types like ‘Patio Princess’ or ‘Bush Early Girl’ for best results in small spaces.
Tomatoes are heavy feeders, so add slow-release organic fertilizer or a regular compost tea regimen to boost fruit production.
2. Peppers
Bell peppers, hot peppers, and specialty varieties all thrive in bucket gardens. They need warmth, sun, and consistent moisture.
Bucket size: 3–5 gallons
Support: Some may need small stakes
Soil: Light, fertile, and well-drained
Watering: Regular, avoid waterlogging
Tips: Peppers prefer slightly acidic soil (6.0–6.8 pH) and lots of sun—aim for 6–8 hours daily.
Use black buckets to increase soil temperature in cooler climates.
3. Cucumbers
Bush or compact cucumber varieties are ideal for bucket growing. Vine types also work if you provide a trellis or vertical support.
Bucket size: 5 gallons
Support: Trellis, cage, or vertical stake
Soil: Moist, fertile, well-draining
Watering: Keep soil consistently moist
Tips: Try varieties like ‘Bush Pickle’ or ‘Spacemaster’ for container success.
Add mulch on top of the soil to retain moisture during hot summer days.
4. Lettuce and Leafy Greens
Lettuce, spinach, kale, arugula, and Swiss chard are excellent candidates for container growing. They grow quickly and don’t require deep roots.
Bucket size: 3 gallons or more
Support: Not needed
Soil: Loose and fertile
Watering: Keep soil consistently moist
Tips: Plant successively every 2–3 weeks for a continuous harvest.
Avoid extreme summer heat or grow in partial shade to prevent bolting.
5. Carrots
Carrots can be surprisingly successful in buckets if the container is deep enough and the soil is loose.
Bucket size: 5 gallons (at least 12 inches deep)
Support: Not needed
Soil: Sandy, loose, and stone-free
Watering: Moderate and consistent
Tips: Choose short or round varieties like ‘Parisian’ or ‘Thumbelina’ for shallow containers.
Avoid heavy, compacted soils that can stunt root development.
6. Radishes
Radishes grow rapidly and don't require much space, making them perfect for small containers.
Bucket size: 2–3 gallons
Support: Not needed
Soil: Loose and fast-draining
Watering: Keep soil moist for tender roots
Tips: Harvest within 3–4 weeks to avoid woody texture.
Mix with slower-growing crops to maximize space.
7. Green Beans
Bush beans are compact and productive, while pole beans require vertical space but offer high yields in limited horizontal space.
Bucket size: 5 gallons
Support: Trellis for pole beans
Soil: Rich, well-draining with added compost
Watering: Moderate, consistent moisture
Tips: Try varieties like ‘Provider’ (bush) or ‘Blue Lake’ (pole).
Beans also fix nitrogen in the soil, which benefits nearby plants.
8. Zucchini and Summer Squash
Compact zucchini and squash varieties can thrive in buckets with enough root space and sunlight.
Bucket size: 5 gallons or more
Support: Not needed unless training upward
Soil: Rich with compost
Watering: Regular, avoid soaking the leaves
Tips: Look for varieties like ‘Eight Ball’ or ‘Bush Baby’ that stay compact.
Remove lower leaves for airflow and disease prevention.
9. Beets
Beets grow best in deep, loose soil and provide both edible roots and greens.
Bucket size: 5 gallons (minimum 10–12 inches deep)
Support: Not needed
Soil: Loose and fertile
Watering: Keep soil evenly moist
Tips: Thin seedlings to 3 inches apart for good root development.
Grow in cooler weather to avoid woody or bitter roots.
10. Onions and Garlic
Both bulb and green onions are container-friendly if spaced properly. Garlic is best started in fall for a late spring or summer harvest.
Bucket size: 5 gallons for multiple bulbs
Support: Not needed
Soil: Light and well-drained
Watering: Moderate
Tips: Use sets or cloves for best success.
Avoid overwatering, which can lead to rot.
Other Container-Compatible Vegetables
In addition to the top ten, several other vegetables grow well in buckets under the right conditions:
-
Eggplant: Needs warmth, full sun, and a 5-gallon container.
-
Turnips: Choose smaller varieties for shallower buckets.
-
Scallions: Excellent for succession planting and harvesting continuously.
-
Pak choi and bok choy: Cool-weather crops that perform well in buckets with regular water.
-
Sweet potatoes: Grown in large buckets with lots of room for sprawling vines.
Setting Up Your Bucket Garden for Success
1. Drainage Holes Are a Must
Drill 4–6 holes in the bottom of each bucket to allow excess water to escape. Without drainage, roots will rot and plants will suffer.
2. Choose the Right Soil
Use a quality container mix, not garden soil. Mixes for vegetables typically include peat moss, coconut coir, compost, and perlite or vermiculite.
DIY mix example:
-
1 part peat moss or coir
-
1 part compost
-
1 part perlite
This ensures aeration, fertility, and drainage.
3. Position for Sunlight
Most vegetables need 6–8 hours of sun daily. Place your buckets in the brightest spot available. South- or west-facing balconies work well. If natural light is limited, use grow lights.
4. Fertilize Regularly
Since buckets drain easily, nutrients leach out quickly. Use:
-
Organic slow-release pellets mixed into the soil
-
Compost tea or fish emulsion every 1–2 weeks
-
Worm castings sprinkled over the surface
Avoid over-fertilizing, especially with high-nitrogen blends, as it may cause lush foliage with few fruits.
5. Watering Wisely
Buckets dry out faster than ground soil, especially in summer. Check soil moisture daily by sticking your finger in up to the second knuckle. Water when the top 1–2 inches feel dry.
Mulch the top with straw or shredded leaves to retain moisture.
6. Pest Control
Buckets reduce some soil-borne pest problems, but you still need to watch for:
-
Aphids
-
Spider mites
-
Whiteflies
-
Caterpillars
Use natural deterrents like neem oil, insecticidal soap, or companion planting (e.g., basil with tomatoes).
Maximizing Space with Vertical Growing
Buckets lend themselves well to vertical gardening techniques. Attach trellises, tomato cages, or bamboo stakes directly into the bucket or nearby walls to support climbing crops like cucumbers, beans, or even compact melons.
Vertical growing increases airflow, reduces disease, and improves harvests in tight quarters.
Succession Planting for Year-Round Harvests
By rotating crops throughout the growing season, you can keep your bucket garden producing. Here’s an example:
-
Spring: Lettuce, spinach, radishes
-
Summer: Tomatoes, peppers, beans
-
Fall: Kale, chard, carrots
Use quick-maturing varieties to get multiple harvests from one container.
Conclusion: A Versatile, Space-Saving Way to Garden
If you're short on space but eager to grow your own food, knowing what vegetables grow well in buckets can open a world of opportunity. From leafy greens and root vegetables to fruiting crops like tomatoes and peppers, a simple five-gallon container can transform your patio or balcony into a productive mini-farm.
The keys to success are proper container setup, the right vegetable selection, and a bit of attentive care. With drainage, good soil, sunlight, and consistent watering, your bucket garden can provide a reliable and satisfying harvest all season long.
