Why rain water is good for your plants | Gardening 101 | Gardening Australia

That’s because the atmosphere has a high percentage of nitrogen, which makes up a large proportion of chlorophyll, the chemical in leaves that makes them green. Plants need that nitrogen to be strong and healthy, but they can’t take it directly from the atmosphere - they need it to be converted to a usable nitrogen source.

During rainfall - and in thunderstorms - that nitrogen is washed in so the plants can use it and become healthy and strong.

Excellent! We were just discussing the possible reasons the other day 👍

I reckon it's got something to do with plants being around for millions of years and have evolved to adapt rain as their main water source. Ol' John Gardener has only been around with his backyard hose for a fraction of the time in comparison.

That’s what I thought. Anyway to replicate the process artificially during droughts?

To much Nitrogen also brings Powdery mildew and aphids. Are they really had bugs or are there job to retire and Elance Nitrogen? When Aphids leave plant do grow well afterwords.Mildew is another story

🤔
Let's go into why NOT 2 use tap water... 'If' possible ...
Heavy Metals, Chemical Treatments ie: pH bufferz, Flouride etc... & wat that does to a plants immune system...
Then maybe go into 'NATURAL' O³ sanitization... mmm that smell ov rain... 🤷🏼
Either way... Good post

Be nice to know if town/city water can actually harm your plants. We have recycled water and I never use it on my edible plants because I suspect they will uptake any contaminants.

Also, does rainwater stored in tanks lose its nitrogen content over time?
