Permanent wilting point

The permanent wilting point is a point in the soil where there isn't enough water for plants to grow. It's like when you're thirsty and your parents forgot to fill up your water bottle. You can't just get a drink from the faucet, so you have to wait until your parents remember to fill up your bottle.

Plants need water to grow, just like you need water to survive. But if there isn't enough water in the soil, the plant's roots can't take up the water they need. When the soil gets really dry, the roots start to dry out too. If the soil stays dry for a long time, the roots will die and the plant won't be able to grow anymore. That's the permanent wilting point.

So, the permanent wilting point is like the point of no return for plants. Once the soil gets too dry, they can't recover no matter how much water you give them. It's important for farmers and gardeners to know about the permanent wilting point so they can water their plants before they reach this point and keep them healthy.
