Pick tomatoes at color break

Ripening off the vine extends harvest, quality with no taste difference

There is a common misconception among the public and home gardeners that vineripened tomatoes taste better. But picking tomatoes at color break does not hurt quality, reduces fruits’ exposure to damage and can extend their shelf-life

Larry Stein, Ph.D., AgriLife Extension horticulturist, Uvalde, said tomatoes are fully mature when they begin to break color. Tomatoes ripen as they begin to produce ethylene gas, which promotes the process.

“Breakers,” mature tomatoes starting to change colors, begin to turn a yellowish green and then begin to fade into salmon-to-pink hues before turning red. Tomatoes can be picked as soon as their green begins to yellow.

There is a difference in taste and quality between some commercially produced tomatoes, but it is based on logistical necessities that do not apply to home gardeners, Stein said.

There is also a difference between tomatoes picked green and ripened via synthesis, Stein said, but no taste or tenderness difference between tomatoes pulled from the vine at color break and those allowed to reach full red color on the vine.

Stein said he has picked his own tomatoes at the first hint of color change for decades. It is standard operating procedure to reduce fruit damage or losses in his garden and his recommendation to gardeners.

Harvesting at color break reduces the chance of pests like stinkbugs and birds harming the fruit, he said. Breaker tomatoes are also less likely to experience radial cracks, splits in the fruit related to water uniformity.

Radial cracks occur because moisture availability is not consistent, Stein said. Fruit swells and cracks when soils receive excess water following very dry conditions.

Picking at break will not prevent all blemishes from stinkbugs but it will reduce exposure to varmint and pest damages, including burrowing pests like fruitworms.

Earlier harvest will also reduce fruits’ exposure to high winds and other various contributors to bruising, he said.

“There are so many reasons to pick tomatoes at color break, and no reason not to,” he said. “It’s just how I have done it forever.”

Storage and ripening

Stein said picking at color break can also allow gardeners to better extend their harvests. The shelf life of ripe tomatoes can be extended in a refrigerator. Refrigerating tomatoes picked earlier in the ripening process puts the ethylene gas production on hold.

Stored tomatoes can then be sequentially ripened at the gardeners choosing. To ripen tomatoes, Stein suggests placing them on a countertop at room temperature. The process should take five to seven days from color break.

“There will be naysayers, but there is no science to support ripening on the vine,” he said. “The quality will be as good, if not better, ripening your tomatoes off the vine rather than on the vine.”
