Streamline produces a fine crop of long beans (30-45 cm). Flavoursome pods and they stay fresher longer on the plants than many other runner beans. Ideal variety for freezing.
For earliest crop sow the runner bean Polestar seeds inside in individual pods about 3 weeks before the last expected frost.
Sow seeds individually in small pots 3-4 cm deep. Keep the temperature between 17-22 Celsius. Transplant outside late June when the plants are strong and all risk of frost has passed.
Outside sowing can be done in late spring (late May- June) when the soil is warm enough for the runner beans. Typically June sowings are recommended. Runner bean seed germination can be eradicated in cold soils, so make sure the soil temperature is around 15 Celsius. Sow the Streamline seeds 3-4 cm deep in well prepared soil. Dig a deeper trench and fill it up with newspaper or cardboardor with half rotted compost, cover this with a bit of soil and sow the runner bean seeds on the top, then cover the seeds with about 4 cm thick of soil. This way the rotting material underneath will provide some heat for the seds and they will germinate successfully and the compost will provide further food for the plants during the growing season.
Allow 15-20 cm between the bean seeds, this is a large seeded runner bean variety. Prefers full sun and rich soil. Pole, trellies, fence or any other form of support is a must for growing runner beans. Unless you want to try our dwraf variety Hestia. Runner beans are one of the most popular vegetables in the UK.
