Water Venus flytraps every 2 to 4 days, depending on the season. The soil must be moist but not inundated at all times. They need to be watered when the soil is somewhat less damp but not completely dry. If there are no signs of life when you water, then overdo it and let the soil become completely dry out between waters. If you overwater them, the plant will die back to the root system and need to be restarted from a new stem. Underwatered plants may appear fine but will eventually succumb to dehydration. Venus flytraps use their leaves as sensors to know when to open their traps. When they detect something with the smell of moisture or food, they close their leaves tightly in order to conserve energy. Then they open their traps when conditions are right for growth. This process repeats itself each time you water your plant. As long as the soil remains moist but not saturated, the plants will continue to grow and develop their seeds pods flowers everything else. When you water your plant too much or not enough, you are causing it to suffer from drought or flooding stress, respectively. Both of these situations can cause serious problems for your plant's health. Overly wet soil can cause the plants' roots to rot if they are not able to breathe properly.
