The pros and cons of bush beans in the greenhouse

Growing French beans in a greenhouse comes with both advantages and disadvantages:
The advantages:

  • the bush beans can be sown earlier and thus harvested sooner
  • the French beans grow a little faster
  • they are less susceptible to the bean fly
  • Damage or crop failure due to late frost is almost impossible

The only disadvantage:

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. Soil temperatures should be above 8°C at sowing and the air temperature at least 12°C. The warmer the soil and air, the quicker the French beans will germinate. The germination period is usually 10 to 30 days.

How long does it take to harvest?

The time to harvest is reduced by up to two weeks when growing in a greenhouse. Instead of the usual eight to ten weeks, you can harvest your bush beans in the greenhouse after about six weeks.

How are French beans grown in a greenhouse?

French beans are weak feeders, but that doesn't mean they don't need nutrients. It is therefore advisable to mix a portion of compost under the soil before sowing.
The most important key data for successful cultivation in the greenhouse are:

  • The seeds are planted 3 to 4cm deep.
  • A planting distance of 30 to 40 cm is advisable.
  • Bush beans like a sunny or partially shaded location.
  • In contrast to pole beans, French beans do not need climbing aids because they do not grow particularly high.
  • Bush beans in the greenhouse should be watered daily. The soil should never dry out, especially until germination.
