Growing a Hyacinth Bean Vine Growing a Hyacinth Bean Vine
A hyacinth bean vine is a fast growing annual that blooms from early summer to early winter. With a deep green foliage and fragrant purple flowers, this dark maroon vine can grow up to 20 feet in one season, twining itself around trellises, fences and posts.
The following simple steps will help you grow this beautiful vine in your garden, and attract hummingbirds.
Step 1 – Prepare the Soil
Pick a sunny location in your garden to plant the seeds. Hyacinth bean vine thrives in an area with direct sunlight or partial shade. Plant your seeds into moist well-drained soil, only after the last frost has passed. Add some compost to the soil to enrich it with the necessary nutrients needed to fuel their season-long growth. Fertilize often, at least once a month.
Step 2 – Plant the Seeds
Plant the seeds an inch deep into the soil with about 6 inches between them. Dampen the soil to make it moist. Adding mulch will increase the appearance and prevent weeds from growing. Water the seeds everyday except when it rains.
Germination will occur between 7 to 20 days.
Step 3 – Thinning the Seedlings
When the seedlings are 2 inches tall, thin them out to space them 10 to 12 inches apart. This will help the remaining seedlings grow stronger to form a healthy vine, without sharing resources.
Step 4 – Caring for the Hyacinth Bean Vine
Hyacinth bean vine is generally low maintenance. Once established, it can grow well even if it is left unattended. Keep the soil moist, not wet. Plants require moderate watering twice a week, more during dry periods.
Pests and diseases are infrequent but will require mild treatment with insecticide if a problem arises.
As the plants grow you may want to support the delicate vine with a trellis or fence. Make sure it is sturdy enough to hold 15 to 20 feet of growth. The vine wraps around any pole or fence that it is provided with ease and requires little training.
Step 5 – Bloom Period
Plants will begin to bloom in the summer and continue until fall. Purple pods will appear after the bloom period and can grow up to 3 inches. The beans inside the pods are poisonous so make sure you keep children away. Collect the raw beans and boil them for a few hours to kill the poison and make them edible.
Hyacinth bean vines have the ability to re-seed, provided the pods are allowed to open naturally and drop their beans. But they will have a better chance if the seeds are collected and stored indoors in a cool dry place until the next growing season.
Enjoy the look of your garden with this pretty plant and its striking color combination all through the summer.
