Does Microwaved Water Really Kill Plants?

There is a popular belief that microwaved water can kill plants. The theory is that the molecular structure of water is altered when it is heated in a microwave, making it harmful to plants. But is there any truth to this?

The Science behind Microwaved Water

Microwaves work by directing electromagnetic radiation towards the water molecules in food, causing them to vibrate rapidly and generate heat. This heat energy is then transferred to other molecules nearby, cooking the food. When water is microwaved, the same process occurs, causing the molecules to vibrate and generate heat.

However, there is no evidence to suggest that the molecular structure of water is altered by microwaving it. Water molecules consist of two hydrogen atoms and one oxygen atom, and these atoms are not changed by microwave radiation. The only change that occurs is the generation of heat energy.

The Effect of Microwaved Water on Plants

So if microwaved water does not alter the molecular structure of water, can it really be harmful to plants? The answer is no. Plants can absorb both microwaved and conventionally heated water without any adverse effects.

Research has shown that any temperature above freezing is sufficient for plants to absorb water. In fact, some studies have even found that microwaved water can be beneficial for plants. The heat generated by microwaving water can help to eliminate harmful bacteria and organisms that may be present in the water, making it safer for plants to absorb.

The Bottom Line

The idea that microwaved water can kill plants is a myth. There is no scientific evidence to support this claim, and plants can absorb both microwaved and conventionally heated water without any negative effects. In fact, microwaved water can even be beneficial for plants by eliminating harmful bacteria and organisms that may be present in the water.

So the next time you need to water your plants and don't have time to heat up water on the stove, feel free to use your microwave without worrying about harming your greens. Just make sure the water is not too hot when you pour it onto your plants to avoid scalding their roots.
