How to Grow Hyacinth Beans
If you are planning to add hyacinth beans to your garden, there are several things to consider to ensure optimal growth and a bountiful harvest.
Ideal Growing Conditions
Areas with warm climates with abundant sunlight are best suited for hyacinth beans. They need to be in full sun and direct sunlight for at least six hours, and like many plants, they are better suited to USDA growing zones 10 and 11. They prefer poorly alkaline soil conditions, have good drainage, and contain prostate organic matter. Even though they are moderately resistant, they require a warm climate to grow effectively. If you live in a cold climate, you can grow them in containers, but you will need to move them to warmer areas in the winter.
Soil Preparation and Planting
Make sure the ground has plenty of nitrogen and is well drained when preparing it for planting. Grow hyacinth beans on slightly acidic to neutral pH soil. As an initial step, apply a top dressing of organic compost to the soil to provide the necessary nutrients. To plant your hyacinth seeds, dig holes in the soil about 1 to 2 inches deep, then space your holes about 6 inches apart. This spacing will give each plant enough space to spread out and grow well.
Hyacinth beans are climbing plants, so it is very important to train them to support, such as a trellis. This will help the plants grow upwards rather than horizontally, reducing competition for space, air, and sunlight for each plant.
Watering and Care
Once established, hyacinth beans can withstand drought, but during their early stages, they require weekly watering. The soil should be moist all the time but not soupy. However, overwatering will cause root rot in the plants, so it’s best to let the soil dry out a bit before watering again.
Fertilization
If one wishes to fertilize hyacinth beans, a balanced fertilizer rich in phosphorous and potassium enhances the flowering and podding of the plant. Take care not to overfertilize with nitrogen because this will result in a lot of leaves and a few beans.

Purple hyacinth beans are sometimes harvested after the pods have dried and become brittle. If you want to use it, you only need to open the beans gently, and you will see the beans inside. The beans at this stage can be prepared to be part of people’s meals, or they can be stored to be used for planting later.
