How Long Do Tomatoes Take To Ripen On The Vine

Tomatoes take anywhere from 20 to 30 days to ripen on the vine after they reach their full green size.

That’s the short and sweet answer if you’ve been staring at those green globes wondering when they’ll finally turn that beautiful red, orange, or yellow.
 
The exact time tomatoes take to ripen on the vine depends on the variety, the weather, and a few other factors we’ll dig into.
 
Some small cherry types might only need a couple of weeks while those big beefsteak tomatoes can keep you waiting for a full month.
 
In this post, we’ll cover how long tomatoes take to ripen on the vine in different conditions and what you can do to speed things up.
 
We’ll also talk about what happens if you pick them early and how to tell when they’re truly ready.
 
Let’s get into the good stuff.
 

How Long Do Tomatoes Take To Ripen On The Vine Exactly?

When you’re asking how long do tomatoes take to ripen on the vine, the answer hinges on a few key stages.
 
Tomatoes go through a green phase where they swell and mature, and only after that does the actual ripening color change kick in.
 
The ripening timer really starts once the fruit has reached its mature green stage, which is when it’s fully grown but still hard and green.
 
From that point, tomatoes take to ripen on the vine in about 20 to 30 days.
 

1. Variety Plays a Massive Role

Some varieties simply ripen faster than others, and this is huge when you’re calculating how long tomatoes take to ripen on the vine.
 
Cherry and grape tomatoes are the speedsters, often ripening in as little as 20 days once they hit mature green.
 
Mid-sized varieties like Roma or Early Girl usually fall right in the middle at around 25 days.
 
Large heirloom beefsteak types can take the full 30 days or even a bit longer to fully ripen on the vine.
 
So if you’re growing multiple types, don’t expect them all to finish at the same time.
 

2. Temperature Dictates the Speed

Temperature is the biggest environmental factor that decides how long tomatoes take to ripen on the vine.
 
The sweet spot for ripening is between 68°F and 77°F (20°C to 25°C).
 
When temps stay in that range, tomatoes ripen on the vine at a steady and predictable pace.
 
But here’s the catch: when it gets above 85°F (29°C), the ripening process actually slows way down.
 
The plant basically hits the brakes because the heat stresses the fruit’s natural pigment production.
 
And if nights stay above 75°F, you’ll also see a delay in how long tomatoes take to ripen on the vine.
 
Cooler temps below 50°F also halt ripening, so don’t expect much progress during chilly spells.
 

3. Sun Exposure Helps But Isn’t Everything

You might think blasting tomatoes with maximum sun would speed things up, and you’re partially right.
 
Direct sunlight warms the fruit, which can help as long as temps don’t climb too high.
 
But too much intense sun can cause sunscald, which leaves pale, leathery patches on the fruit.
 
What really drives the color change is the naturally occurring ethylene gas inside each tomato.
 
Light helps the plant produce sugars, but the actual ripening hormone is produced regardless of sun exposure.
 
So while sun is great for overall plant health, it’s not the main switch that flips when tomatoes take to ripen on the vine.
 

Signs Your Tomatoes Are Almost Done Ripening

If you’re tracking how long tomatoes take to ripen on the vine, you’ll want to know exactly what to look for as they near the finish line.
 
The first sign is a subtle change in the fruit’s color, shifting from a deep, dull green to a lighter, almost yellowish green.
 
This is called the “breaker stage,” and once you see it, full ripening is usually just a week or two away.
 
The fruit will also start to soften slightly when you give it a gentle squeeze.
 
A ripe tomato gives a little under pressure but still holds its shape, it shouldn’t feel mushy.
 
Another clue is that the tomato will easily separate from the vine with a slight twist.
 
If you have to yank hard, it’s not ready yet, so give it more time on the vine.
 

How To Speed Up Ripening On The Vine

Sometimes you just want those tomatoes to hurry up, especially if frost is coming.
 
Even though tomatoes take to ripen on the vine on their own schedule, you can nudge them along.
 
One trick is to pinch off any new flowers or tiny fruit at the top of the plant.
 
This redirects the plant’s energy into ripening the existing mature tomatoes instead of making new ones.
 
You can also trim back some of the larger leaves shading the fruit clusters.
 
Just don’t strip the plant bare, you still need leaves for photosynthesis, but a little extra airflow helps.
 
Another method is to stop watering as much once the fruit hits mature green size.
 
Mild water stress signals the plant to focus on finishing what’s already there.
 

What If You Pick Them Early?

If you’re wondering whether you can skip the wait and pick green tomatoes, you absolutely can.
 
Tomatoes will ripen off the vine just fine, and this is a lifesaver when frost threatens your crop.
 
The trick is to pick them at the mature green stage, meaning they’re fully grown and glossy.
 
If they’re smaller than the variety’s normal size, they won’t ripen well off the vine.
 
But if you pick them at the right time, place them in a warm spot out of direct sun, and they’ll finish ripening in about one to two weeks.
 
This doesn’t change the fact that tomatoes take to ripen on the vine when left alone, but it’s a handy backup plan.
 

So, How Long Do Tomatoes Take To Ripen On The Vine?

Tomatoes take about 20 to 30 days to ripen on the vine once they’ve reached full green size.
 
But as we covered, that timeframe stretches or shrinks depending on the variety and your local weather.
 
Keep an eye on the breaker stage color change, feel for a little give, and track those temperatures.
 
If you do all that, you’ll have perfectly ripe tomatoes right on schedule.
 
Hope this helps you nail down exactly how long do tomatoes take to ripen on the vine in your own garden.
 
Happy growing, and enjoy every juicy slice when they finally turn!
