Container gardening has revolutionized the way gardeners work with limited space, urban environments, and even challenging soil conditions. Buckets and barrels, traditionally used for storage or waste, have emerged as practical, inexpensive, and versatile planting containers. With the right plant selection, these containers can support lush flowers, productive vegetables, and even small fruit-bearing plants.
This article explores five plants that thrive in buckets and barrels, along with tips for soil, watering, fertilization, and maintenance to help gardeners achieve productive and beautiful container gardens.
Why Use Buckets and Barrels for Gardening
Buckets and barrels offer several advantages for container gardening:
- Cost-Effective: Reuse materials that might otherwise go to waste.
- Spacious Containers: Large barrels allow ample root growth for bigger plants.
- Mobility: Buckets and barrels can be moved to optimize sun exposure or shelter from harsh weather.
- Customizable Drainage: Drill holes for water drainage to suit plant needs.
- Urban Gardening Friendly: Perfect for patios, balconies, and small yards where in-ground planting is impossible.
By selecting appropriate plants and container sizes, gardeners can grow a wide range of flowers, herbs, vegetables, and fruiting plants in these unconventional containers.
1. Tomatoes – Juicy and Productive
Tomatoes are a popular choice for large containers like buckets and barrels due to their extensive root systems and high yield potential.
Growing Tips:
- Use a 5-gallon bucket or larger barrel for each plant to allow roots to spread
- Drill drainage holes at the bottom
- Fill with high-quality potting mix enriched with compost or slow-release fertilizer
- Provide a cage or stake for support as plants grow
Best Varieties for Containers:
- Cherry tomatoes: Compact and highly productive
- Patio tomatoes: Ideal for smaller spaces with controlled growth
- Determinate varieties: Grow to a fixed size, making them easier to manage in containers
Maintenance Tips:
- Water consistently, keeping soil evenly moist but not waterlogged
- Fertilize every 2–3 weeks with a balanced or tomato-specific liquid fertilizer
- Remove suckers to encourage fruit development
Why They Thrive:
Buckets and barrels provide enough space for roots, while being easy to manage for irrigation and support, making container-grown tomatoes highly successful.
2. Strawberries – Sweet and Compact
Strawberries are another excellent candidate for buckets and barrels, especially because they thrive in containers that elevate them off the ground, reducing pest problems.
Growing Tips:
- Use a large bucket or barrel for multiple plants or a single dwarf variety per smaller bucket
- Ensure drainage holes to prevent root rot
- Mix potting soil with compost for nutrient-rich planting medium
- Position containers in full sun for 6–8 hours daily
Best Varieties for Containers:
- Alpine strawberries: Small, compact, and continuous producers
- June-bearing strawberries: Produce a large harvest over a few weeks
- Ever-bearing varieties: Provide fruit throughout the growing season
Maintenance Tips:
- Water regularly, keeping soil moist but not soggy
- Fertilize lightly during the growing season with a balanced fertilizer
- Remove runners if you want to focus on fruit production rather than spreading
Why They Thrive:
The elevated position of buckets and barrels promotes air circulation around the plants, reducing fungal diseases and making harvesting easier.
3. Leafy Greens – Lettuce, Spinach, and Kale
Leafy greens are well-suited for medium to large buckets and barrels because they do not require deep soil and grow quickly in containers.
Growing Tips:
- Use a 2–5 gallon bucket for individual plants or a larger barrel for multiple plants
- Ensure proper drainage to prevent soggy roots
- Mix soil with compost for consistent nutrients
- Place in partial to full sun, depending on the species
Best Varieties:
- Lettuce: Butterhead, romaine, or leaf lettuce varieties
- Spinach: Fast-growing and cold-tolerant
- Kale: Hardy, suitable for repeated harvests
Maintenance Tips:
- Harvest outer leaves regularly to encourage continuous growth
- Fertilize every 2–3 weeks with a liquid or slow-release fertilizer
- Thin seedlings to prevent overcrowding
Why They Thrive:
Leafy greens have shallow root systems and grow quickly, making them ideal for the limited soil volume in buckets and barrels.
4. Herbs – Culinary and Aromatic
Herbs are a versatile choice for container gardening, thriving in small to medium-sized buckets. They provide fresh culinary ingredients, pleasant fragrances, and even pest-repelling properties for companion planting.
Growing Tips:
- Use small buckets (1–3 gallons) for individual herbs or a larger barrel for mixed herb gardens
- Ensure well-draining soil and moderate watering
- Place containers in sunny spots, at least 4–6 hours of light daily
Popular Herbs for Buckets and Barrels:
- Basil: Thrives in summer warmth and produces continuous harvests
- Thyme: Hardy and drought-tolerant
- Parsley: Fast-growing and versatile in cooking
- Mint: Grows vigorously; contained in a bucket to prevent spreading
Maintenance Tips:
- Regularly prune herbs to promote bushy growth
- Fertilize lightly with organic or balanced fertilizer
- Harvest frequently to encourage new growth
Why They Thrive:
Herbs adapt well to container environments and are low-maintenance, making them perfect for balcony, patio, or rooftop gardens using buckets or barrels.
5. Dwarf Fruit Trees – Citrus and Fig
For gardeners with larger barrels, dwarf fruit trees are a rewarding option. They can produce fruit year after year while remaining manageable in containers.
Growing Tips:
- Use a 15–20 gallon barrel for a single dwarf tree
- Ensure excellent drainage to prevent root rot
- Use a rich, well-draining potting mix supplemented with compost or organic fertilizer
- Prune regularly to maintain size and shape
Recommended Varieties:
- Dwarf lemon or lime trees: Compact, fragrant, and productive
- Fig trees: Hardy, suitable for warmer climates
- Dwarf peach or nectarine trees: Require slightly more space and care
Maintenance Tips:
- Water deeply but allow the soil to dry slightly between waterings
- Fertilize monthly during the growing season with a fertilizer suitable for fruit trees
- Protect from frost in colder climates using covers or moving the barrel indoors
Why They Thrive:
Barrels provide enough soil volume for root expansion while allowing for careful control of soil, water, and nutrients, making dwarf fruit trees viable even in small spaces.
Tips for Successful Gardening in Buckets and Barrels
- Ensure Proper Drainage: Drill adequate holes to prevent waterlogging.
- Use Quality Potting Mix: Avoid heavy garden soil; mix in compost or perlite for aeration.
- Monitor Watering: Containers dry faster than in-ground soil; water consistently.
- Fertilize Regularly: Nutrients leach out faster in containers, so periodic fertilization is essential.
- Choose the Right Container Size: Match plant size and growth habit to bucket or barrel volume.
- Rotate or Move Containers: Adjust placement seasonally for sunlight and protection from wind.
- Prevent Soil Compaction: Fluff soil periodically and avoid overwatering to maintain root health.
Environmental and Practical Benefits
- Urban Gardening Friendly: Buckets and barrels allow gardening in apartments, rooftops, and patios.
- Sustainability: Repurposing containers reduces waste and promotes eco-friendly gardening.
- Pest Control: Elevated plants in barrels or buckets are less prone to slugs, snails, and ground pests.
- Aesthetic Appeal: Large barrels create statement pieces, while small buckets provide flexible plant arrangements.
Final Thoughts
Gardening in buckets and barrels combines creativity, practicality, and productivity. By choosing the right plants—tomatoes, strawberries, leafy greens, herbs, and dwarf fruit trees—gardeners can transform small spaces into thriving, productive green oases.
With proper soil selection, drainage, watering, fertilization, and maintenance, container-grown plants can achieve vigorous growth, abundant harvests, and vibrant beauty. Whether for ornamental purposes, culinary use, or sustainable urban gardening, buckets and barrels provide versatile and cost-effective options for modern gardeners seeking high yields in limited space.
By embracing these simple strategies and plant selections, gardeners can enjoy lush, productive, and beautiful container gardens year-round, turning ordinary containers into extraordinary gardens.
