Product Description
Blue Lake Climbing Bean is one of the most widely grown pole bean varieties in the world. It combines excellent eating quality with strong garden performance, making it a reliable choice for home gardeners, market growers and seed savers.
The vigorous vines produce long, smooth, round pods that are crisp, tender and naturally stringless when harvested young. Regular picking encourages continuous flowering and helps maintain heavy production throughout summer and early autumn.
Unlike bush beans, Blue Lake grows vertically, allowing gardeners to maximise productivity from small growing spaces. Plants perform best when grown on a sturdy trellis, netting or fence where pods remain clean, easy to harvest and highly visible.

How to Grow Blue Lake Climbing Beans
Direct sow seeds into fertile, well-drained soil once temperatures have warmed and frost danger has passed. Beans dislike root disturbance and perform best when sown directly where they are to grow.
Install a trellis, netting, fence or climbing frame before sowing. This allows young plants to establish quickly and climb naturally as they grow. Keep soil evenly moist during germination, flowering and pod development.
Mulch around plants to conserve moisture and suppress weeds. Avoid excessive nitrogen fertiliser, as beans naturally fix nitrogen and excessive leafy growth can reduce pod production.
Regular harvesting encourages continued flowering and helps maintain high yields throughout the season.
Harvest
Harvest pods when they are young, smooth and tender, typically around 12–15 cm long. Pick every few days during peak production to encourage new flowers and ongoing pod development. For the best eating quality, harvest before pods become overly mature.
