Beans need a lot of water when they are first planted. In fact, you should water them daily until they sprout. Many people like to soak their seeds in water before they plant them.
This allows the outer shell to soften so the plants can germinate faster. If you choose to do this, you will need to plant the beans within 24 hours of soaking them. Once the beans sprouts, they require less water but should be checked regularly to ensure that they are not drying out.
If the beans receive too much water, the water could set near the roots of the plant and lead to root rot. It’s a good idea to plant the beans in soil that is well-drained. This will ensure the plants are getting all the water they need without being overwatered. The water can drain down into the soil, and the plants can absorb it as needed.
