5. Why does a plant die when it is pulled out of soil?
Answers
Answer: Most soils have a large supply of nutrients in them, and they get taken up by plants when plants absorb water. ... Nutrients need to be added to replace what is taken out, and the best way to do this is test the soil. Too many nutrients, and it pollutes streams and groundwater, and too little, the plants may die
Explanation:
Sure, some plants will do just fine. Back in the old days over here in Europe, cactus collectors would pull out their specimens from their soil in fall, wrap them up in newspaper and store them in the attic until spring.
Then re-pot and the cactus will do just fine. Most of the roots will be dead, of course, but not the taproot or root-base. It will grow them back once there is some moisture available. The reason for doing this was to avoid keeping the plants in the warm living room for winter, and avoiding them to rot when being kept in soil in the dark attic. If you keep a cactus warm for the usually sunless winter months it will produce unhealthy, ugly growth.
You can even cut off a cactus at its base and leave it sitting for a few weeks protected from direct sunlight and rain. Then place in sand and it will grow roots again. Some cacti, specially bigger ones, can live for more than a year out of the pot. Or in completely dry soil. They may shrink, but they will be fine once being watered again.Some plants, if pulled from the soil but left lying on top of the soil, will just go on growing.
Some plants do not do well even if you replant them and will likely die no matter how much care you give them.
Answer:
Because plants need water to grow and the reproduce in soil . so, when we pull then out from the soil they die.
