As a gardener, in my experience “volunteer” plants that randomly sprout up tend to be way more robust than the ones you plant. I believe that this is because of all the seeds that have randomly been scattered without care, the ones that manage on their own have genetics that better suit them for the environment. As a consequence, when I see a random tomato plant (or other) growing I’ll usually carefully dig it up and replant it in my garden. If the plant was thriving without care, giving it just a little bit of care makes it grow even better.
I saw a neat video recently from one of those rewilding organizations about how they’re doing basically the same thing to expand native forests at a rate faster than it would regenerate on its own. Apparently the nursery grown saplings tend to drop dead when someone stops caring for them, but saplings transplanted from a few hundred meters away were already taking care of themselves and are more likely to survive.
That’s awesome!
There’s a brick wall at my work that has moss on it, and growing from that moss is a plant. About 7 feet up a brick wall. It’s very silly to look at.
Some things used in water treatment may be more detrimental to plant growth. You can try letting the water sit for a day before using so some things may evaporate out.
