There are many reasons why you might choose to start growing grapes, not only are they beautiful, but they also produce lots of grapes for years and years after you plant them.
However, you probably have some questions about growing grapes. The top question you might have is how hard are they to grow? The answer is it is not very hard at all as long as you grow them in the correct climate.
What Temperature Do Grapes Grow In?
The target temperature range for grapes is from 77 to 90 degrees Fahrenheit (which is about 25 to 32 degrees Celsius). Grapes will experience the most amount of growth that they can if they are kept somewhere in this temperature range.
Additionally, it is normally best if the temperature is kept toward the higher end of that range during the early bud development stage of growth, and then moved towards the lower end of the optimal range as the plants get close to flowering.
As you will see in the rest of this article, the temperature is a very important variable that will greatly affect the success of your grape-growing endeavors. Not only could nonoptimal temperatures hinder a grapevine’s growth, but they could also ultimately lead to the death of the plant.
What Temperature Can Grapes Tolerate?
Grapevines will be able to tolerate temperatures outside of the optimal zone, the exception to this would be extreme temperatures. Extreme temperatures in either direction, hot or cold, would result in the death of the grapevine.
As long as your grapevines aren’t exposed to temperatures at or below freezing level (32 degrees Fahrenheit / 0 degrees Celsius) then they can tolerate other cold temperatures, but if temperatures reach freezing then the plant itself will freeze which could cause damage.
On the other end of the spectrum, grapevines can die if temperatures reach 100 degrees Fahrenheit or higher (this would be about 38 Celcius). But if the temperatures reach 95 degrees Fahrenheit (35 degrees Celsius) then the plant will start to sustain damage even if it doesn’t die.
Can Grapes Get Too Much Sun?
Like most plants, grapevines need sunlight to grow. But if the grapes are exposed to direct sunlight for too long then it can cause serious problems such as sunburn and burning of the leaves as well which can hinder growth.
There will be some variations of grapes that need more direct sunlight to grow, but even those variations need to have their time in the sun monitored. A grapevine will never need more than about 7 hours of direct sunlight a day.
Make sure that you’re growing your grapevines in a place with plenty of shade, and remember that it is possible to simulate sunlight to some extent which can be helpful if you can’t have your grapes in a sunny place.
Can Grapes Survive Winter?
It is possible for grapes to survive winter but it is also possible for grapevines to sustain winter injury that could damage them and possibly lead to their death. The plant may survive even after winter injury if you let the vine regrow from the base of the plant.
Keep in mind that even though grapevines can technically survive winter, the early spring is still the best time to plant them. This gives the plants time to mature before the harsh winter weather sets in.
If you wait to plant the grapes until fall then they will still be in their very vulnerable early stages, and will therefore be more susceptible to the cold weather. By giving the plants more time to establish themselves, you’re increasing the likelihood of their survival.
What Temperatures Can Grapes Grow Indoors?
The optimal temperature to grow grapes doesn’t vary much whether you choose to plant them indoors or outdoors, but you have significantly more control of the temperatures that your plant is exposed to if you plant the grapevines inside.
You should strive to keep the temperatures indoors around the same temperatures that the plants would experience in an optimal environment outdoors. A suitable temperature for grapes to stay in would be above 60 degrees Fahrenheit (15 degrees Celsius).
You could also lower that temperature range a bit in the colder months to emulate what the plants would be experiencing outdoors. Just remember to never keep the temperature too hot, such as the 95 degrees Fahrenheit (35 degrees Celsius) level that we talked about earlier.

What Is The Ideal Temperature For Grapes To Grow?
Whether you’re growing your grapes indoors or outdoors, in the spring or in the winter, and no matter what climate you live in, it’s best if you keep the plants in a place where the temperature is in the range of 77 to 90 degrees Fahrenheit (25 to 32 degrees Celsius).
If you’re growing your grapes outdoors then it could be considerably trickier, if not impossible, to keep the temperature in this range depending on where you live. For this reason, many people choose to grow grapes indoors where they’re more in control of the environment.
But even if you’re not in complete control of the temperatures your grapes are exposed to, they can still grow and thrive as long temperatures don’t reach the critical zones of being far too cold or far too hot.
So in short, although you know what the ideal temperatures are for grapes, they are very easy to grow and can be grown in many different climates and environments. Just make sure that you know about all the variables you can and how they’ll affect your variation of grapevine.
Things like sunlight, humidity, and insects are also key factors to consider when you’re thinking of growing grapes. And you need to have a plan in place for all of these things to be successful during this gardening endeavor.
