How to Grow Green Bean Plant Outdoors

Updated: April 21, 2022

Growing green beans is an easy and rewarding experience for any gardener. Whether you’re a seasoned gardener or just starting out, growing green beans is a great way to get started. Green beans are a popular vegetable that is easy to grow, nutritious, and delicious. They are also very versatile and can be used in many different recipes. In this article, we will show you how to grow green bean plants outdoors.

Choosing the Right Variety

When choosing the right variety of green bean plant, it’s important to consider your climate and growing conditions. There are two main types of green beans: bush beans and pole beans. Bush beans are great for small gardens or containers because they grow only 1-2 feet tall and do not require any support. Pole beans, on the other hand, grow tall and require support to climb. They are ideal for larger gardens or trellises.

Some popular varieties of green beans include:

  • Blue Lake
  • Kentucky Wonder
  • Provider
  • Contender
  • Roma II

Preparing the Soil

Green beans prefer well-drained soil that is rich in organic matter. Before planting, prepare the soil by removing any weeds or debris and adding compost or aged manure. Work the soil with a garden fork or tiller to loosen it up and create a fine texture.

Planting Green Beans

Green beans can be planted directly into the ground after the last frost in your area. For best results, plant seeds about 1 inch deep and 3 inches apart. If you are planting pole beans, make sure to provide support for them to climb on. You can use a trellis, teepee, or even stakes with twine.

Watering and Fertilizing

Water your green bean plants regularly, especially during dry spells. It’s important to keep the soil moist but not waterlogged. Overwatering can lead to root rot and other problems. Fertilize your green bean plants with a balanced fertilizer about once a month.


Green beans are ready to harvest when they are about 4-6 inches long and the pods are firm and bright green. Pick the beans regularly to encourage more growth and prevent the pods from becoming tough and stringy. You can store green beans in the refrigerator for up to a week.

Common Problems

Green beans are generally easy to grow, but they can be susceptible to some common problems such as:

  • Aphids: These tiny insects can suck the sap from the leaves and cause them to wilt. Use an insecticidal soap or neem oil to control aphids.
  • Bean Beetles: These pests can eat holes in the leaves and damage the pods. Handpick them or use an insecticide to control them.
  • Powdery Mildew: This fungal disease can cause a white powdery coating on the leaves. Improve air circulation by spacing plants out, and remove infected leaves.


When is the best time to plant green beans outdoors?

Green beans should be planted after the last frost in your area, usually in late spring or early summer.

How often should I water my green bean plants?

Water your green bean plants regularly, about once a week or more during dry spells. Keep the soil moist but not waterlogged.

Can I grow green beans in containers?

Yes, bush beans are great for containers because they don’t require any support and grow only 1-2 feet tall.

How do I know when my green beans are ready to harvest?

Green beans are ready to harvest when they are about 4-6 inches long and the pods are firm and bright green.

How do I prevent pests and diseases from attacking my green bean plants?

Keep your garden clean and free of debris, and remove any infected leaves or plants immediately. Use organic insecticides or fungicides if necessary.
