Growing vegetables in 5-gallon buckets is a great way to garden in small spaces. These containers offer plenty of room for roots and make it easy to control soil, water, and nutrients. Whether you have a patio, balcony, or backyard, bucket gardening allows you to grow fresh produce without a traditional garden bed. Here’s how to prepare your buckets, choose the best vegetables, and care for your plants from planting to harvest.
Preparing 5-Gallon Buckets for Gardening
Before planting, make sure your buckets are ready. Start by choosing food-grade buckets to avoid harmful chemicals. If repurposing buckets, clean them thoroughly with soap and water.
Next, drill drainage holes in the bottom. Use a ¼-inch drill bit to create at least five to six holes to prevent water from pooling. For better drainage, drill a few holes along the lower sides as well. To keep soil from washing out, place a layer of mesh or small gravel over the holes.
Best Soil Mix for Bucket Gardening
Vegetables need nutrient-rich, well-draining soil to thrive. Avoid using garden soil because it compacts in containers. Instead, mix potting soil with compost for a balanced blend. A good mix includes:
- 60% high-quality potting soil
- 30% compost or well-rotted manure
- 10% perlite or vermiculite for drainage
This mix provides the right texture and nutrients for healthy root growth. Before planting, moisten the soil to ensure even water distribution.
Best Vegetables to Grow in 5-Gallon Buckets
Several vegetables grow well in buckets. Here are some top choices:
Tomatoes
Tomatoes thrive in containers and need support as they grow. Choose determinate varieties like Roma or Bush Early Girl. Plant one tomato seedling per bucket and place a stake or cage for support. For more in depth post on how to grow tomatoes in a 5 gallon bucket-just click here.

Planting and Caring for Vegetables
Once your buckets and soil are ready, it’s time to plant. Follow seed packet instructions for depth and spacing. If using seedlings, plant them at the same depth as their nursery containers. After planting, water thoroughly to help roots establish.
Watering
Containers dry out faster than garden beds, so consistent watering is essential. Check soil moisture daily by inserting a finger about an inch deep. If it feels dry, water until excess drains out. Most vegetables need watering every day in hot weather.
Fertilizing
Vegetables in containers need regular feeding. Use a balanced liquid fertilizer (10-10-10) every two weeks. For heavy feeders like tomatoes and peppers, supplement with a calcium-rich fertilizer to prevent blossom-end rot. Organic options like fish emulsion or compost tea also work well.
Mulching
Adding a layer of mulch helps retain moisture and regulate soil temperature. Use straw, shredded leaves, or grass clippings to keep roots cool and reduce watering needs.
Harvesting Your Vegetables
Harvesting at the right time ensures the best flavor and texture. Pick tomatoes when they turn fully red and peppers when they reach their desired color. Harvest lettuce and greens by snipping outer leaves, allowing the plant to keep producing. Pull carrots and radishes when they reach the right size. Regularly picking beans and cucumbers encourages more production.
Final Tips for Success
To keep your bucket garden thriving, rotate crops each season to prevent soil depletion. Keep an eye out for pests like aphids and caterpillars, removing them by hand or using insecticidal soap. Clean and store your buckets at the end of the season to use them again next year.
Growing vegetables in 5-gallon buckets is an easy and rewarding way to produce fresh food, even in small spaces. With proper preparation, soil care, and consistent maintenance, you’ll enjoy a bountiful harvest all season long.
