When you think of growing grapes, probably what comes to mind is rolling hills of vineyards and beautiful climbing grapevines. It's not a plant one immediately jumps to when thinking about fruits and vegetables that can be grown indoors. Is it even possible to grow grapes indoors? We have researched this to find out just how possible this might be.
It is possible to grow grapes indoors with the right preparation. Here are the steps you should follow -
- Determine if you have enough space
- Procure grapevine plants in the right variety
- Plant in proper pots
- Provide structure for the vines to grow on
- Feed, water, and light appropriately
- Harvest
We're going to take a more in-depth look at how you can successfully grow grapes indoors. And we'll provide you with a couple of handy resources as well.
Growing Grapes Indoors In Containers
It is possible to grow grapes indoors if you have enough space. A grapevine likes to spread out, and its tendrils will grab hold of whatever it needs as it stretches out. So it's best to build it a frame out of bamboo stalks that are contained within the pot to keep it from grabbing onto furniture. You will want deep pots, around 16" and enough room for your vines to spread out at about your arm's span.
Which Varieties Of Grapes Grow Best Indoors?
There are a few varieties of grapes that do well indoors. Let's take a look.
Dessert Grapes
These sweet grapes like Muscat of Alexandria and Black Hamburgh will do well indoors.
Close To The Trunk Grape Clusters
These varieties include Early Muscat, Seyval, Canadice, Interlaken, or Swenson Red.
This Canadice grape produces sweet, seedless fruit that ripens in mid-August to September. You can buy these plants as 1-2 yr old starts, shipping in 1-gallon pots, and shrink-wrapped for safety.

Other Grape Varieties For Containers
Buckland Sweetwater, Black Hamburgh, Rembrandt, Gros Maroc, Fosters Seedling, Chasselas Rose, and Royal Muscadine are also said to be suitable for growing indoors.
This Chasselas Rose variety is grown on a bonsai type vine indoors in a pot. This grape is delicious and sweet. Here is a link for high-germination seeds to start these vines on your own.

Muscadines are a variety of grape that grows wild in many parts of the southern United States. It can also be cultivated in pots and is a wonderful addition to an indoor or balcony garden. Click here to purchase a plant on Amazon.
The Best Containers For Growing Indoor Grapes
As already mentioned, grapes take up more space than many other indoor plants because of their vining properties. You'll need a pot at least 16" in-depth, and a minimum of 18" circumference or 24" if a rectangular planter. You'll also want to be sure you have some sort of trellis situation for the vines. Otherwise, your walls, window frames, and furniture may be overtaken by luscious grapevines.
We've found some interesting pots and trellises that could work for growing grapes indoors.
This expandable willow teepee is interesting for its flexibility. It folds and expands as needed and gives plenty of vining opportunity for your grapevines. Plus, it's so easy to open it up and place it over any style pot.

This hydro-farm tomato trellis is super awesome. It's on wheels, so it is easy to move around. At 30" wide, it's big enough for grapes (even though it's only 14" deep), and the trellis expands up to 4' to hold vines laden with fruit. It has an easy watering port at the bottom. There are several other models and configurations from this same company. Click here to see this on Amazon.
This 5' tall obelisk design trellis cage is sturdy and is quite beautiful, as well. It can put directly in your planter, and your grapevine will look amazing, tangling its way up the rings.

We love these elegant cubed planters. They are an abundant 24" deep by 24" square and will work for grapevines beautifully. Made out of a stone and fiberglass combination, they are not lightweight, but at 40 lbs are lighter weight than actual stone planters. These come in several colors and shape configurations if you're looking for something super elegant for your indoor garden.

The Feeding And Watering Of Your Indoor Grapes
When prepping your planters for growing your grapes, you don't want generic potting soil. Start by putting some small stone at the bottom of the pot, then use a moist silt loam that's rich in organic materials for your mix.
Water your plants well, making sure the moisture goes down six to ten inches into the soil. Then, be sure and let it dry out completely between waterings. This will help prevent root rot.
At the start of the growing season, use a nitrogen-rich fertilizer to spur spring growth. But you'll want to lay off of fertilizers as your fruit begins to ripen because it may affect the flavor of the grapes.
What Is The Best Temperature For Growing Grapes?
Grapes love sun and warmth. Ideally, your grapes will have a full seven hours or more of sunlight per day. If you can give them up to 12 hours by use of an indoor grow light, then your yields of fruit will be higher. In general, grapes need around 150 days when the temperatures are above 50 degrees to thrive. But that's the nice thing about growing them indoors, your home is probably never going to be below 50 degrees and as long as they're watered, heat shouldn't be a problem.
How Fast Do Grape Vines Grow And Produce Grapes Indoors?
This is not a fast plant. Be prepared to keep purchasing your grapes from the supermarket for at least three years. Because that's how long it takes from seed to first fruiting of a grapevine. Germination of seeds can take anywhere from two weeks to two months, depending upon the amount of sunlight they receive.
Here's a handy rule of thumb. If you buy a grapevine in a 1-gallon pot, chances are it's 12-18 months old. A 2-gallon pot means a 24-30-month-old plant, and a 3-gallon pot means a vine that is at least 3-4 years old and, therefore, ready to produce fruit. You'll pay more for a mature plant, but then you'll be ready to go.
Are Grapes Easy To Grow?
If you can provide them with what they need—plenty of sunlight, abundant room, and time to mature—then sure, they're easy enough to grow. However, grapes do come with a bit of extra TLC needed. They need to be able to vine and attach their tendrils to things. They will need pruning at least twice during the growing season. They need their water level checked regularly to make sure the soil is watered shortly after drying out. And they need a big sunny, warm window or a grow light to provide their necessary sun requirements. On top of all that, they need time, at least three years from seed to producing vine.
