Why we tested the Gardener’s Blue Ribbon Ultomato
Traditional conical tomato cages are 33 to 36 inches tall. Most indeterminate tomato varieties grow to 5 or 6 feet. The result is a cage that stops being useful by midsummer while the plant continues growing unsupported above it. The Ultomato advertises 6-foot adjustable height as a solution to this problem. We tested it through a full growing season to see whether the height and support claims hold under real conditions.
We installed five Ultomato cages in a home vegetable garden with a mix of Brandywine, Cherokee Purple, and Sun Gold cherry tomato plants. All plants went unsupported until cage installation in early June, then grew within the cages through final harvest in September.
How we tested the Ultomato
- Supported five plants through a full growing season from early June through September harvest
- Measured maximum plant height at harvest (tallest plant reached 5 ft 8 in inside cage)
- Assessed cage deflection under load at peak fruit weight (mid-August)
- Timed setup and takedown per cage for storage assessment
- Stacked 8 cages and measured total storage footprint

Who should buy the Ultomato?
Buy this if: You grow indeterminate tomato varieties, have struggled with standard cages that become inadequate by July, or want to solve the storage problem that piles of traditional cages create. Also excellent if you grow large-fruiting varieties like Brandywine where weight on the cage is significant.
Skip this if: You grow determinate varieties only and your plants reliably stay under 4 feet, in which case the $25 per unit cost is not justified. A $18 Titan or $20 4-pack works for shorter plants.
Structural support: what a tomato cage should be
At peak fruit load in mid-August, our Brandywine plant was carrying an estimated 8-10 lbs of fruit plus a full canopy of foliage. The Ultomato held without any visible deflection or tipping. The heavy-gauge wire did not bend at the horizontal ring connections, which is the first failure point on cheaper cages. The wide base provided enough stability that the cage did not need staking, even in the clay-heavy soil in our test plot.
Storage: the real competitive advantage
Traditional conical cages do not nest inside each other the way catalog photos suggest. In reality a stack of five traditional cages takes up significant corner space in any shed. Eight Ultomato cages folded flat occupied the space of roughly one traditional cage stack. This sounds like a marginal benefit until you are trying to store 12 tomato cages in a small shed in October.
Setup: honest assessment
Assembly takes 2-3 minutes per cage on first use while the folding mechanism is unfamiliar. By the second or third cage the time drops to under 90 seconds. Takedown at season end takes about the same time. For gardeners who set up and tear down cages twice a year, the extra time over a simple cone cage is negligible.
Verdict
The Ultomato earns the Best Overall designation by solving real problems that standard cages do not address: adequate height for full-size indeterminate plants, genuine weight support, and practical storage. The $25 price per unit is fair for what it delivers.

Should you buy the Gardener's Blue Ribbon Ultomato Tomato Plant Cage?
The Ultomato is the cage that replaced every conical wire cage in our test garden. At up to 6 feet tall it handles indeterminate varieties properly rather than letting them flop above a 36-inch cone. The fold-flat design means a full season's worth of cages stores in the space of one traditional cage. The $25 price per unit is higher than basic cages, but the adjustable height and 70-pound weight support justify it for serious tomato growers.
Frequently asked questions
Does the Ultomato work for determinate tomato varieties?+
Yes. For determinate varieties that stay under 4 feet you can simply set the cage to a lower height setting. The fold-flat storage advantage still applies. You are paying for height capacity you may not need, though.
How does it fold flat in practice?+
The cage collapses by folding the vertical support sections inward. The result is roughly 1.5 inches thick per cage. A stack of eight cages takes up about the same floor space as a single standard cone cage.
Will it rust after one season?+
After one full season in the ground, the base sections showed minor surface oxidation at the soil contact points, which is normal for any steel cage. The above-ground wire was clean. Storing indoors over winter prevents most season-to-season degradation.
