The warmer it is, the faster the French beans will germinate. A floor temperature of 20 ° C is ideal. In this case, a germination time of only 10 days, possibly even less, would be expected. The warmer the ground at the sowing, the bigger the harvest will be, which is why it is advisable not to sow French beans until June or July. In addition, the plants are more resistant to pest infestation.
If you don't fully trust the climate and want to be on the safe side, you can prefer your French beans at home.
