Tomato

Cherry Tomatoes.

Small fruit, high count, and labour as the deciding cost.

Eaten raw, priced on flavour

Cherry tomato is eaten raw and whole, usually out of the hand rather than out of a pan. Nothing is peeled off and nothing is cooked away, so what the fruit carries when it is cut from the plant is what reaches the person eating it.

Flavour is where that shows first. Sugar and acid are built in the fruit while it is still attached, and they stop being built the moment it is picked. Fruit harvested early enough to survive a journey colours on the way and still tastes of the day it left. The class is priced on flavour, which makes the harvest date part of the price.

A short chain also keeps more of the crop saleable. Cherry is sold by the punnet, and one soft fruit takes the pack with it, so days spent in transit are days the pack can be lost. Picking at colour and delivering the same week protects the eating quality and the pack together.

Cherry tomato is a separate market class from truss, sold both on the vine and loose, and priced on flavour and appearance rather than on weight alone. The fruit is small, so a house produces a very large number of them for a given tonnage, and picking and packing become the dominant variable cost. That is the crop’s central commercial tension: the premium is real, and so is the labour required to capture it.

What the crop needs

The plant is long-cycle on substrate and high wire, like truss tomato, but it carries a much larger number of smaller fruit. Plant load management is therefore the daily craft, and the balance between vegetative and generative growth has to be held tightly to keep sugar levels and fruit size consistent across a long season. Climate and irrigation strategy are directed at flavour and shelf life as much as at total mass.

What the greenhouse has to do

Cherry tomato asks the house for consistency and for flow. The structure and the climate envelope are shared with truss tomato; what changes is the number of fruit moving through the building every week. Path width, internal transport and the size of the packing area are part of the greenhouse design rather than something fitted around it once the crop is in.

Climate is steered at quality. Screening and heating hold the day-to-night rhythm that keeps sugars and fruit size even across a long season, and drip supply with drain recirculation keeps the root zone from swinging. Where the market window reaches into the low-light months, supplemental light and the electrical service to carry it belong in the brief from the start, because both change the heating design with them.

DutchGreenhouses® specifies the structure, climate, screening and irrigation around the cherry tomato crop, its sale form and the local climate, so flavour and count hold across the season. Get in touch to plan a tomato greenhouse for your market.

Questions

Cherry tomato, asked and answered

Is cherry tomato more profitable than truss?

It carries a higher price per kilogram and a higher labour cost per kilogram. Which wins depends on local labour rates, the degree of harvest and pack automation, and the premium the market actually pays.

What changes in the greenhouse when the crop is cherry rather than truss?

Mostly the handling. The structure and the climate envelope are shared; the difference is the number of fruit moving through the house every week, which sets path width, internal transport and the size of the packing area.

What decides cherry tomato flavour?

Cultivar sets the ceiling; climate, irrigation strategy and plant load decide how close a crop gets to it. Flavour is steered before harvest, not after.
