I have been asked several times Can green beans be grown indoors? The answer is Yes. Green beans are a staple in most outdoor gardens. They can be stable for your indoor garden too. Let look closer at how to grow green beans indoors.
The first thing that you need to keep in mind is that there are different varieties of green beans. Different beans will have different needs.
What beans can you grow indoors?
There are two most common types of green beans: Pole beans and Bush beans.
Pole beans may not be the right choice for most indoor spaces. As the name suggests, pole beans are climbers. These beans are vines. They will grow as a long single main stem that can reach 15 feet tall!
The good news for indoor pole beans is that they only take about a foot in width over the 10-15 feet long. That means that if you want to be creative and have a long space to fill, such as over a long window or around the ceiling, pole beans could be a fun and tasty addition to your indoor garden.
Common Pole Bean varieties include:
Kentucky Wonder Pole AKA Old Homestead
These are some of the most popular kinds of pole beans grown. Kentucky wonder beans are known for their great flavor and stringless pods.
These plants grow pretty purple flowers and sweet stringless beans.
One of my favorites! They have a high yield, easy to grow, with sweet and tender stringless beans. Plus, they are purple! How can you go wrong?
Bush beans are just what they sound like. These plants grow in a compact bush about 2 ft round. The beans themselves are the same as pole beans without the vining plant.
This compact size makes bush beans perfect for almost any indoor space. The plants no trellis or other supports are needed to grow.
Some good varieties include:
This is an heirloom variety with long, tender pods. Pods come to be up to 6″ long.
This is the one I use most often. Easy to grow is cool rooms as well as warm. The beans have a strong flavor that doesn’t get lost when cooking.
Purple is the new green! These are dark purple on the outside when growing. The inside is green, and the whole bean turns green when cooked.
How do you grow green beans indoors?
Light to grow beans indoors
Lighting is always a concern when planning and growing your indoor garden.
Most green beans varieties need at least 6 hours a day of full sun. Like most plants that have fruit, these plants do not do well in the shade.
The six-plus hours of full sun can be achieved in different ways. If you have a full sun south-facing window, then you will be able to grow wonderful plants. However, if you have limited sunny options in your home, you can still grow a great indoor garden.
Natural sunlight can be supplemented with full-spectrum grow lighting. You can grow your green beans in a window with a grow light that comes on when there is limited sunlight at the window. Putting the light on a timer or even using a sensor to regulate when the light comes on can save on your electric bill.
If you are growing your indoor garden with no natural light, you can still have a healthy garden by using grow lighting. The nice thing about growing without relying on the sun is that you are sure your plants are getting exactly what they need.
Soil and containers for indoor green beans
Green Beans grow best in soil that is well-drained and rich in compost. Get a good vegetable container mix or other rich soil.
If you have soil that is not specially designed for container gardens, then make sure that you add some material like sand or vermiculite to help with drainage. Poor drainage is the most common cause of problems with growing green beans indoors.
Green beans need some room to grow. An 8″ container is good for green beans. Bigger containers are good; however not needed and may be harder to keep well watered.
PH for Green beans
The PH soil levels that green beans like best are between 6.0 and 6.8

The temperature needed for good indoor green beans gardens
Green beans have a pretty wide temperature tolerant range. Most will continue to grow in temps as low as 50 degrees and as high as 85 degrees. This makes green beans perfect for indoor growing as they are well within the range that most people keep in their homes.
Soil temperature is important when first planting seeds. The best soil temperature is in the 65-70 degree range. Warm up your soil with a seed heating pad if needed. This will ensure your plant gets the best start.
Harvest your indoor green beans
Harvest time is the best time. You can enjoy the benefits of all your care.
I have been known to eat all the beans raw while harvesting them more than once! Few make it to the kitchen.
Fresh grown beans are tastier than anything you can buy at the market.
The number of beans will vary greatly with different varieties, so check the packaging to determine how many plants will fit your needs.
In general, the seed to harvest for green beans is about two months.
Try adding a bean plant or two; you may find that indoor green beans are among your favorites in your indoor garden.
