Growing tomatoes vertically in backyard crates is a smart way to maximize space while producing a healthy, abundant harvest. This method is especially useful for small gardens, patios, or urban backyards, where horizontal space is limited but vertical space can be put to good use. By combining the rustic charm of wooden crates with the efficiency of vertical gardening, you can enjoy flavorful, homegrown tomatoes without needing a large plot of land.
Why Grow Tomatoes Vertically in Crates?
Tomatoes are naturally vining plants, and when grown vertically, they make better use of sunlight, have improved airflow, and are easier to maintain. Using crates as the base planters offers even more advantages:
-
Space efficiency: Perfect for small yards or narrow garden areas.
-
Better plant health: Vertical growth keeps foliage and fruit off the soil, reducing the risk of rot and pests.
-
Ease of maintenance: Watering, pruning, and harvesting are simpler when plants grow upward.
-
Aesthetic appeal: Crates provide a rustic, decorative touch to a functional setup.
Choosing the Right Crate and Support
Your crate is the foundation of this gardening method, so choose wisely.
-
Size: A crate at least 14–16 inches deep ensures enough space for tomato roots.
-
Material: Use untreated, sturdy wood that can handle moisture without warping quickly.
-
Drainage: Drill holes in the bottom for proper water flow.
-
Lining: Landscape fabric or burlap can be used to hold the soil in while allowing water to drain.
For vertical support, you can use stakes, trellises, or even tall tomato cages. Attach them securely inside or alongside the crate so the structure stays stable as the plants grow heavier with fruit.
Selecting Tomato Varieties
Not all tomatoes grow equally well vertically. While determinate (bush) varieties are compact, indeterminate (vining) varieties are the best choice for vertical setups because they keep producing throughout the season and grow upward naturally.
Great options include:
-
Cherry tomatoes: Sweet, bite-sized, and fast-growing.
-
Roma tomatoes: Ideal for sauces and canning.
-
Beefsteak tomatoes: Large, juicy fruits perfect for slicing.
If space is extremely tight, look for compact indeterminate hybrids designed for container growth.
Preparing the Soil Mix
Tomatoes are heavy feeders and need nutrient-rich, well-draining soil.
Recommended mix:
-
40% high-quality potting soil
-
40% compost or aged manure
-
20% perlite or coarse sand for aeration
Mix in a slow-release organic fertilizer before planting. Tomatoes also benefit from adding crushed eggshells or a calcium supplement to help prevent blossom end rot.
Planting in Crates
-
Start seedlings indoors 6–8 weeks before the last frost, or purchase healthy transplants.
-
Fill the crate with your soil mix, leaving 2 inches from the top.
-
Plant one tomato per crate for best results. Bury the stem deeply, covering part of the lower leaves—tomatoes develop roots along buried stems, creating a stronger root system.
-
Water thoroughly after planting to help the soil settle.
Training Tomatoes to Grow Vertically
Once your tomato plant starts growing, guide it upward:
-
Tie stems loosely to the support using soft garden ties or strips of cloth.
-
Prune regularly by removing suckers (small shoots in leaf axils) to focus energy on fruit production.
-
Rotate the crate occasionally to ensure even sun exposure on all sides.
Sunlight and Watering Needs
Tomatoes love warmth and require 6–8 hours of direct sunlight daily. Place your crates where they will receive the most consistent sun.
For watering:
-
Keep the soil evenly moist but not waterlogged.
-
Water deeply at the base rather than overhead to prevent fungal issues.
-
Mulch the surface with straw, shredded leaves, or coconut coir to retain moisture and regulate soil temperature.
Feeding for Maximum Yields
Feed tomatoes every 2–3 weeks with a balanced liquid fertilizer until flowers appear, then switch to one higher in potassium and phosphorus to encourage fruiting. Avoid too much nitrogen, as it leads to leafy growth rather than tomatoes.
Pest and Disease Management
Vertical growing in crates naturally reduces some issues, but stay watchful:
-
Aphids: Spray with water or neem oil.
-
Tomato hornworms: Remove by hand or use natural predators like ladybugs.
-
Blight: Ensure good airflow and avoid wetting the leaves when watering.
Harvesting
Tomatoes are ready when they’re fully colored and slightly soft to the touch. Pick them gently to avoid damaging the vine. Frequent harvesting encourages the plant to keep producing.
End-of-Season Care
When the growing season ends, remove the plants and discard any diseased material away from your compost pile. Refresh the soil in the crate before replanting next year. If you have a greenhouse or sunny indoor space, you can even bring crates indoors to extend the harvest into cooler months.
Final Thoughts
Vertical tomato growth in backyard crates is a perfect blend of practicality and charm. This method makes the most of small spaces, keeps plants healthy, and simplifies harvesting—all while producing delicious homegrown tomatoes. Whether you’re growing sweet cherry tomatoes for snacking or large slicing varieties for summer sandwiches, this approach will reward you with bountiful harvests and an attractive garden setup.
