How to Grow Tomatoes Upside Down
ðą How to Grow Tomatoes Upside Down
A Step-by-Step Guide
✔ Why Grow Tomatoes Upside Down?
-
Saves space in small areas
-
No need for staking or cages
-
Creates great sun exposure and airflow
ðŠī What You’ll Need
-
Drill (if using a bucket)
-
Potting mix (light, well-draining)
-
Tomato seedling (best varieties below)
-
Watering can or hose
Best tomato varieties for upside-down growing:
Cherry tomatoes • Roma • Grape • Patio hybrids • Tumbling varieties
ð§ Step 1 — Prepare the Planter
If using a bucket:
-
Drill a 2–3 inch hole at the bottom center.
-
Drill 4–6 small side holes near the top edge for drainage and hanging.
-
Install a strong hook or chain—your plant will become heavy.
ðŋ Step 2 — Insert the Tomato Seedling
-
Turn the bucket upside down.
-
Gently feed the tomato seedling stem-first through the bottom hole.
-
Have someone hold it in place OR place a piece of newspaper/cardboard around the stem to stabilize it.
✔ The leaves should hang outside; the root ball stays inside the bucket.
ð§ą Step 3 — Add Soil
-
Carefully turn the bucket upright while holding the plant in place.
-
Fill with a light potting mix (avoid garden soil).
-
Mix in a handful of slow-release fertilizer.
-
Leave 2–3 inches of space at the top.
ðĶ Step 4 — Hang and Water
Hang the planter on:
-
A strong hook
Water thoroughly until it drips through.
ð Step 5 — Give it Full Sun
Tomatoes need:
-
6–8+ hours of sunlight daily
-
Warm temperatures
-
Protection from strong wind
ðļ Step 6 — Maintain the Plant
-
Water daily, sometimes twice in hot weather
-
Add liquid fertilizer every 1–2 weeks
-
Prune any suckers if the plant gets too bushy
-
Harvest regularly to encourage more fruit
ð Tips for Best Results
-
Choose lightweight soil to avoid compacting.
-
Don’t overwater—ensure good drainage.
-
Add a small herb (basil, parsley) on top of the soil—it helps shade and retain moisture.
-
If stems curve upward, that’s normal; tomatoes always grow toward the sun.
This increased productivity is due to increased air circulation to the leaves when the plant is hanging in midair, more disease resistance from avoiding contact with garden soil, and improved nutrient absorption from watering and fertilizing from the bottom of the plant.
You can grow any variety of tomatoes upside down. However, smaller fruited varieties are preferred, for obvious reasons.
Some pruning may be needed to keep plants under control.
Building an Upside Down Planter
The ideal planter for growing tomatoes upside down is a 5 gallon bucket with a metal handle. Studies have shown that 5 gallons is the ideal container size to maximize the space/production ratio of tomato plants.
A light growing medium should be used. A good mixture would be 50% sphagnum peat moss, 30% compost, and 20% perlite. Here are the steps to building an upside down planter for growing tomatoes upside down:
1. Drill a hole about 3” in diameter on the bottom of the bucket
2. Prepare your tomato transplant by removing all but its top set of (big) leaves.
3. Hang the bucket right-side-up with its handle somewhere low so you can reach to the bottom. Remove your transplant from its container and carefully stick the plant through drilled hole so that the plant is sticking out from the bottom of the bucket.
4. With one hand holding the plant, start packing peat moss inside the bucket around the stem all the way up to its roots.
5. Fill the bucket with the tomato growing mixture until about an inch from the top.
6. Hang the bucket at its final destination where it will reside and water thoroughly.
7. About 5 days after transplanting, fertilize from the top with a water-soluble fertilizer.
And there you have it, a good-to-go tomato plant grown upside down. Like all container vegetables, make sure to water and fertilize it regularly.
An automated container drip watering system can also be set up with your upside down planters.
