The advantages and disadvantages of bush beans in the greenhouse
Growing French beans in a greenhouse has both advantages and disadvantages:The advantages:

When can beans be sown in the greenhouse?
Since the temperatures in the greenhouse are significantly higher than outdoors, beans can be sown here as early as the end of April. When sowing, soil temperatures should be above 8°C and the air temperature should be at least 12°C. The warmer the ground and air, the faster the bush beans germinate. The germination period is usually 10 to 30 days.

- A planting distance of 30 to 40cm is advisable.
- Bush beans like a sunny or partially shaded location.
- In contrast to pole beans, bush beans do not need any climbing aid as they do not grow particularly tall.
