There are a lot of different kinds of beans out there, but not many can steal the spotlight from the simple green bean. Whether baked in a casserole, eaten as a healthy snack, or taken to market, growing your own beans can be an excellent pastime. But there’s one small catch. You need to grow them on a pole because they are a vining plant that does best when it is climbing.
Growing beans on a pole or trellis may seem like a lot of extra work to save space in your garden. All of these beans can be grown in a bush form instead, but utilizing a pole will do more than just save space. Growing your beans vertically will lead to larger and more reliable harvests. Pole bean pods are easier to harvest, and some gardeners swear the beans taste better as well.
If you’re willing to put the work in up front, these beans will more than prove their worth. Here’s how you can get started.
The ideal soil temperature for pole beans is around 70 degrees Fahrenheit. The best time to sow is after the spring frost. The soil also needs to be somewhat fertile, but adding a little compost can solve that problem. Be sure to use compost with little to no manure—doing so will keep some pests away. Pole beans also need a lot of moisture. Mulch is a perfect solution to maintain a proper balance.
How to Plant Pole Beans
The first thing you’ll need is either a trellis or stake for your plants. Pole beans can reach up to five to 10 feet tall, so keep that in mind when making preparations. Plant your seeds directly into the soil, three inches apart and one inch deep. You will need to thin them out as they grow, leaving space up to four inches between each young plant.
Caring for Your Pole Beans
As mentioned before, it is important to keep the soil moist. Adding mulch to the area around plants [https://www.gardeningchannel.com/4-ways-to-mulch-your-vegetable-garden/] will help your soil retain water. Early in the morning, before the heat of the day, is the best time to water your beans. During hot summer weather, be sure to keep the roots moist. Light watering is fine until the flowers bloom. Remove the flowers as they fall, as too much nitrogen in the soil will yield you fewer pods.
Pests and Diseases
Unfortunately, pests enjoy beans as much as people do. Aphids, cutworms, and beetles of a few different varieties are a few notable species with an appetite for beans. Some bugs can wash off when watering, but be sure to check your plants daily afterward for signs of infection. Quarantine or dispose of infected plants, and make sure to keep their foliage dry. White mold can also afflict pole beans in the right environment. Mosaic virus, a genetic virus that can affect plants, is another threat. This infection can cause leaves to become discolored and display a mosaic-like texture.
Harvesting and Storage
Pole beans are ready to harvest as soon as the pods have matured. Picking the pods as they grow can increase your yield. Pods are ready to pick when they are firm and a good size. To remove them, snap or cut off the pods. Do not tear pods from the plant—this rough treatment will cause damage. Pole beans can stay fresh for four days. They tend to toughen over time however. Pole beans will keep best if canned, pickled, or frozen.
