why do plants do well sitting with their roots in just water, but once you’ve planted them they start to rot if the soil is too wet?

* when roots are submerged in a lot of water, there is sufficient oxygen in the water for them to absorb…in soil, the oxygen in the water is quickly used up and the deoxygenated water blocks the air
* rot is often caused by mold, which requires both water and nutrients from soil…no soil, no mold

Root rot is usually because of lack of oxygen! Lots of plants have no problems with submerged roots, as shown with successes in hydroponics. But the key is that the water solution is aerated and moving rather than stagnant.

Life is the simple answer. Rot begins when life forms begin eating away at organic matter.

In the soil are all kinds of microorganisms, many of which decompose organic material. Those life forms generally have trouble living in water, thus cannot rot the roots. There are life forms that can do that in water however, which is why you keep your water clean.
