How to Harvest and Preserve Green Beans

Green Beans are Super to Harvest

and Easy to Preserve

Green beans will make you feel like a gardening guru! They are super easy to grow, mature quickly, and give you lots of green beans per plant.

Green beans are not only easy to grow, they are easy to harvest and easy to preserve. The best thing about green beans is that they don’t require much attention and they are very prolific for the effort you put into them. They are ready to harvest somewhere around 8 weeks after you plant the seed.

Harvest at the Perfect Time

Green beans can go from bloom to harvest in ten to fourteen days. the beans on the left/top are blooming with young beans only two and three days old. The beans on the right/bottom are the perfect size to pick. The seeds inside are still small and the pods are tender. Don’t let them get too big or they will be stringy and tough.

Get Your Canning Supplies Ready First

The Canner

Before you harvest your beans, get your supplies ready. I use a Presto Canner. It’s a big investment, but once you have it, you will never have to buy another one unless you want two! And I used two when I canned for a family of nine. I still have one of those canners and it is somewhere around thirty years old.


Purchase jars that are specifically meant for canning. Don’t try to use jars that are not canning jars. They will not stand up to the pressure and they will break during the canning process. Jars are another expense but, if you take care of them, they will last for many, many years. You can use either pint sized jars or quart sized. One quart is four very generous servings. One pint is a generous two servings.

Seals and Rings

I have always taken my rings off the jars once they are cooled and sealed. They tend to rust and become difficult to remove if they are left on the jar during storage. Some people prefer to leave them on just in case the seal didn’t really seal. If a seal didn’t seal and you put it away that way, eventually, the contents will expand and possibly overflow the jar. That has never, ever happened to me in thirty years of canning. I’ve only read about it.

Ready to Harvest Green Beans

How to Pick Beans from a Bush

When you pick a green bean, try to pull them off in an upward motion using only enough “tug” to take them off the plant. There will be immature green beans that will be ready over the next two to three weeks so you don’t want to pull so hard that the whole plant is uprooted! Take time to move the bush gently and see if there are beans hiding under the leaves. It’s important to pick ALL ripe beans. That sends a signal to the plant to keep making beans!

How to Pick Beans from a Vine

You will be pulling the beans off the vine in an upward pull, just as described in the bush variety. My experience has been that the mature beans are hidden more under the leaves. Be sure to move the vines and look from the dirt all the way up the vine!

For just a little

A garden journal is exactly what you need to keep track of what worked and what didn’t. All this is done for you! For just a little, you can get a printable document that’s got you covered from your seed wish list to your harvest records. There are 39 pages of charts, record keeping, garden map grids, and lots of pages for your garden journaling about the garden in general as well as the individual veggies and fruit that you are growing. It’s only $4.99! You can find out more details and order it here and get started right away. (A digital version is also available in the shop.)

Wash the Beans

Wash the green beans and drain to dry. It’s not totally necessary to dry but it makes the “snapping” part easier. Fill a sink with enough water that will cover the beans. You can be pretty vigorous with the “swishing”. Repeat one time and that should clean them. Place them in a dish drainer or towel. Let dry for a couple hours if you have the time.

Relax and Snap Your Beans

Prepare Your Snapping Room!

Spread an old sheet on the floor. You will be tossing the ends and bad pieces onto the sheet. A smooth sheet is easy to shake out when you are done and it makes a big area that you can toss the ends onto. I’m all about easy and saving time!

Fill a large pot full of beans, go sit in your easy chair and start snapping. I snap off an end, toss it onto the sheet, snap the bean into one to one and a half inches long until I get to the other end. Then toss that end onto the sheet, pick up another bean and keep on going until the pot is done. It’s really that easy!

Preserve Green Beans by Canning

The first time you can green beans, you won’t believe how easy it is. Since the beans are already washed, you can simply fill the jars to the “shoulder” of the jar. Tap and shake the jar a little and you will be able to fit more in. Do not fill above the shoulder. Add one-half to one teaspoon of salt on top of the beans. Now fill the jars with water just a tiny bit over the level of the beans. It really doesn’t make a difference which kind of water you use. I have water from a well, but if I had county or city water, I would use filtered water. But, that is just a preference and not essential.

Wipe the top of the jar with a clean cloth. Position a new lid (seal) onto the jar and then secure that in place with a “ring”.

Place the empty canner onto a large burner. Put the rack that is included with the canner in the bottom of the canner. DO NOT place jars directly onto the bottom of the canner. Now arrange the jars into your canner, six around the edge and one in the middle. Seven, quart jars will fit. Shift them around a little to have a little space between the jars. Now fill the void between the jars with water until you get half-way up the jar. Place the seal into the lid of the canner. Carefully line up the arrows as your canning instructions tell you and twist the lid in place.

Pressure Cooker is ON

Green beans need ten pounds of pressure. Follow the directions for your canner. The weight will look different for different canners. Turn the heat on high and wait. It will take up to thirty minutes before you hear the weight start to jiggle. At that point, you can turn the heat down to medium-high. This is when you call the whole process, “process”! So, process for 25 minutes for quart sized jars. At the end of that time, simply turn off the heat. You do not need to shift the canner off the burner unless you want to. I don’t. It’s heavy.

It will take an hour for the canner to cool down naturally. DO NOT quick release the canner. If you have smaller pressure cookers or an instant pot, you know what this means. To put it another way, wait until the lock releases on its own.

Once you are sure the pressure is off, the lid will unscrew easily. Remove the lid. I use a jar lifter at this point but you can use a good potholder or several layers of a kitchen towel to remove the jars. Cool them on a rack or towel. You will soon hear a “pop” as the lids seat securely down. Once they are sealed, the beans will last for years. I know that is not considered safe to eat, I’m just saying the jar will stay sealed for years.

A Side Note About Rings

I have always taken my rings off the jars once they are cooled and sealed. They tend to rust and become difficult to remove if they are left on the jar during storage. Some people prefer to leave them on just in case the seal didn’t really seal. If a seal didn’t seal and you put it away that way, eventually, the contents will expand and possibly overflow the jar. That has never, ever happened to me in thirty years of canning. I’ve only read about it.

I believe that you can design a peaceful lifestyle while you homeschool, complete with a garden if you want, and meals that will make the best memories you ever could imagine!

I homeschooled seven kids through high school, starting them all with a lot of planned, hands-on activities. Then, I centered subjects around the activities. That gave them lots of room for their natural curiosity to be satisfied as they learned about God’s world.

Let me help you teach kids, grow food, and stay calm!
