Growing soybeans in the garden is becoming increasingly popular among home gardeners, and for good reason.
Soybeans are an excellent source of protein, fibre, and vitamins, making them a great addition to any kitchen garden. With just a few simple steps, you can have your own crop of fresh soybeans ready for harvest in no time!
In this guide, we’ll cover everything you need to know about growing soybeans in the garden, from selecting the right variety of seeds and preparing the soil, to harvesting and storing your crop. So let’s get started!
All About Soybeans
Before you begin, it’s important to understand the basics of soybean gardening. Soybeans are a type of legume that is native to East Asia and widely grown around the world.
They come in many varieties, from the common black-seeded variety to the more exotic yellow-seeded variety. Each variety has its own unique flavour and texture, as well as different growing requirements.
Soybeans require very little maintenance and can be grown in most climates. They thrive best in warm weather, but will also tolerate cool temperatures. To get the best yield, it’s important to choose a variety that is suited to your climate and soil type.
Planting Soybeans
Now that you know the basics of soybean gardening, it’s time to learn about planting them in your garden. The first step is to choose a location with plenty of sunlight and well-draining soil. Soybeans need at least 6 hours of direct sunlight each day, so pick a spot that gets ample sunshine throughout the day.
Next, you’ll need to prepare the soil. Soybeans prefer a slightly acidic pH level (5–7).
Once the soil is ready, you can start planting your soybean seeds! Plant them about 1 inch deep and cover lightly with soil. Water thoroughly and keep the soil moist until germination, which usually takes about 10 days.
Care
Sun and Temperature
As they grow, soybeans need plenty of sunshine and warmth.
Water and Humidity
Soybeans need consistent moisture, especially during the hottest months. Aim for 1-2 inches of water each week and monitor the soil to make sure it doesn’t dry out. In addition to regular watering, soybeans also thrive in high humidity levels.
If your climate is too dry, you can mist the plants once a day or set up an automatic irrigation system.
Fertiliser
Soybeans do not need a lot of fertiliser, but they will benefit from an occasional boost. Organic fertilisers such as compost or manure are best for soybean plants. Once the plants reach maturity (about 60 days after planting), you can add a layer of compost around them to help give them an extra boost.
Pruning and Weeding
Once your plants reach maturity, it’s important to keep up with regular pruning and weeding. Prune any dead or diseased leaves and remove weeds as soon as they appear. Also, make sure to keep an eye out for pests such as aphids, which are attracted to soybeans.
Propagation
If you’re looking to save money by propagating your own soybean plants, it’s actually quite easy. All you need to do is collect the beans from mature plants and allow them to dry on a screen or paper plate.
Once the seeds are completely dry, store them in an airtight container until planting time.
Harvesting and Storing
When it comes time to harvest your soybeans, you’ll want to wait until the pods are dry and brown before picking them. Once picked, they can be stored in an airtight container for up to 6 months.
Troubleshooting
Growing Problems
If your soybean plants don’t seem to be doing well, there could be a few different reasons. The most common cause of poor growth is improperly prepared soil or inadequate watering.
Pests and Diseases
Soybean plants are susceptible to a variety of pests and diseases. The most common are aphids, spider mites, and powdery mildew. To prevent these problems, keep your plants healthy by providing adequate water, sunlight, and nutrients.
You can also use natural pest control methods such as neem oil or insecticidal soap to manage any outbreaks.

How should I prepare the soil before planting soybeans?
It’s important to prepare the soil before planting soybeans in order to ensure healthy plants and successful harvests. First, make sure the soil is loose and well-draining.
Adding lots of organic matter such as compost or manure can help improve drainage and add nutrients to the soil.
Additionally, if your soil is acidic, you may need to add limestone or other amendments to raise the pH level.
Which type of soybeans should I plant?
There are a few different types of soybeans available, including determinate and indeterminate varieties. Determinate varieties produce all their beans in one batch before dying off, while indeterminate varieties continue to produce over time for a longer harvest season. Decide which type works best for your climate and gardening goals.
Which varieties of soybeans are best for home gardens?
Two popular varieties of soybeans for home gardeners are ‘Envy’ and ‘Midnight’. Both varieties have good disease resistance and produce an abundance of small, tender beans. Additionally, they both grow well in a variety of climates and soil types.
Does the soil need to be warm for soybean plants to grow?
Yes, the soil should be at least 65°F (18°C) before you plant your soybeans. If your soil is too cold, it can slow down germination and stunt growth. You can use a soil thermometer or wait until all danger of frost has passed in your area before planting your soybeans.
Do I need to water my soybean plants?
Yes, it’s important to provide adequate water for healthy growth and development. Soybeans prefer moist soil, so make sure you give them about 1-2 inches of water each week while they are growing. As the pods begin to mature, reduce watering to prevent the beans from getting too soft.

Additionally, store your seed in an airtight container away from moisture and sunlight to preserve freshness.
Are there any pests or diseases I should watch out for?
Yes, there are a few pests and diseases that can affect soybeans. Common pests include aphids, whiteflies, and the soybean cyst nematode. Diseases such as anthracnose and bacterial blight can also cause problems. To prevent these issues, use natural pest control measures such as neem oil or insecticidal soap and practice crop rotation with other vegetables in your garden.
Do I need to fertilise my soybean plants?
Yes, it’s important to fertilise your soybean plants throughout the growing season. A balanced fertiliser or one high in nitrogen can help promote healthy growth and development.
Additionally, adding compost or manure to the soil before planting will provide essential nutrients for your plants as well.
What is the best time of year to grow soybeans?
The best time of year to grow soybeans depends on your climate and location. Generally, soybeans should be planted in the late spring or early summer when the soil is warm enough for germination. In cooler climates, you may need to wait until mid-summer or even early fall for optimal growth and development.
Does it matter how long I let my soybeans mature?
Yes, letting your soybeans fully mature will increase the nutritional value and flavour of the beans.
Additionally, waiting until the pods are dry will ensure that they keep longer after harvesting. You can tell when the beans are ready to be harvested when the pods turn yellow and start to crack open.
Do I need to remove the beans from the pod before storing them?
No, you can store both fresh and dried soybeans in their pods. For fresh beans, keep them refrigerated in a sealed container for up to two weeks.
Dried beans can be stored at room temperature in an airtight container for up to one year. Both types of beans should be protected from moisture and heat to ensure longevity.
Can I save soybean seeds from year to year?
Yes, you can save soybean seed for up to three years if stored correctly. Store the seeds in a cool, dry place away from direct sunlight and make sure they are kept in sealed containers or vacuum-sealed bags.
Additionally, any beans that have been damaged or diseased should be discarded before storing.
