Bush beans germinate within 10 to 30 days, depending on temperature and sowing depth. Below you will find out which conditions favor the germination of bush beans and how you can harvest earlier.
How long does it take for bush beans to germinate?
The germination period of bush beans is between 10 and 30 days, depending on the temperature and sowing depth. A soil temperature of 20°C, an air temperature of at least 12°C, loose, moist soil and as little wind as possible are ideal for rapid germination.
Optimum conditions for germinating bush beans
Bush beans are very sensitive to cold and should under no circumstances be sown outdoors before May. To germinate you need:
- at least 8°C soil temperature
- at least 12°C air temperature
- loose, moist soil
- Sun
- as little wind as possible
The bush beans will germinate at a soil temperature of only 8°C, but it can take up to 30 days until you see the first plants.
The warmer it is, the faster the bush beans will germinate. A soil temperature of 20°C is ideal. In this case, a germination time of only 10 days, possibly less, would be expected. The warmer the ground when sowing, the larger the harvest will be, which is why it is advisable not to sow bush beans until June or July. This also makes the plants more resistant to pest infestation. If you don't trust the climate completely and want to be on the safe side, you can prefer your bush beans at home.
Prefer bush beans
Bush beans can be preferred in different ways:
- on the windowsill
- in the greenhouse
- in the cold frame
To grow bush beans at home, sow the beans in seed trays (€35.00 on Amazon) or place the seeds on damp cotton in an elongated, shallow container. Then stretch a piece of cling film over the beans. Make sure that the substrate or cotton never dries out.
Tip
Bush beans thrive on raised beds because the soil temperature is higher. You can find out how to grow your bush beans on a raised bed here.
