Green beans are a delicious and popular legume that are well known for being versatile in a lot of different cuisines and cooking styles. Green peas can be easily grown on a balcony, so if you live in an apartment or condo, you can grow some amazing green beans right outside your balcony door. The following guide will teach you how to grow green beans on a balcony.

Note: The following instructions are for bush green beans, not pole green beans.

Before Getting Started

The following is some essential information you need to know before you get started with your balcony green beans.

  • Climate: Green beans are meant to be grown in warm weather. Plant them after the last spring frost, ideally when the average temp is around 70 degrees.
  • Sunlight: Green beans need about 6 to 8 hours of full sunlight every day.
  • Planter: Opt for large containers to give green beans the most room to grow; planters should be at least 15 inches in diameter and 12 inches deep.
  • Indoors or Outdoors? Green beans can be easily grown indoors, as long as you have access to a window or area that receives a lot of sunlight. If you grow them on your balcony, you can bring them indoors during the hottest summer days to keep the plants from scorching; you can also grow them indoors in the winter for a winter harvest.

What You’ll Need

The following are the basic supplies you’ll need to grow green beans on your balcony.

  • Green bean seeds
  • Soil
  • Container
  • Fertilizer
  • Drip watering system (optional)

Step by Step Instruction

Here’s how you can get started with growing green beans on your balcony.

1. Prepare your container

First, prepare your container; make sure it has drainage holes for the soil. Fill your container with nutrient-rich potting soil that is designed to hold moisture.

2. Plant your green beans

Plant your green bean seeds about 1 inch down; if you are planting more than one in the same container, they need at least 3 inches of space in between.

3. Maintain your plant

If you are using a drip watering system, aim for your green bean plant to get about 1/2 inch of water while it is growing. You may reduce this to 2 inches per week once the plant begins to mature, but keep an eye on the moisture level. Fertilize once a month during the growing season.

Growing Notes

Keep the following in mind for your balcony green beans.

  • Water: Green beans should be given about 1/2 inch of water per day while they are growing. Be careful to avoid getting plant soil on the leaves when watering (i.e, do not water forcefully!) as this increases the chance of disease. You should consider using a drip watering system to keep the plant consistently watered without over watering it.
  • Growth: It will take about 50 to 70 days for your green beans to go from planted seeds to mature plants that are ready to harvest.
  • Maintenance: Green beans are vulnerable to lots of pests, so make sure you keep an eye out for pests like aphids and bean leaf beetles, which can destroy a green bean plant.
