I have two plants on the draining board in my kitchen. One plant - a Begonia - has had a rough time over the last five or six years. I bought it in a garage on the way home from the theatre. After flowering once, it went into a steep decline and broke off from it's roots.
My first reaction was to put it in the bin, but I just couldn't, not while there was life in it. I stuck the rootless stem back into the soil and for the next five years it did little other than just hang on in there. Then last Christmas, my other plant, an anonymous specimen, decided to flower.
One night, after watering the mystery plant, I left it with the feeble begonia. I don't know if it was love or envy, or copycat behaviour, but within days, the begonia had started to grow rapidly.
I was (and still am) unsure if the stem has re-rooted and so I built a scaffolding comprised of a clothes-peg, a chopstick, a pencil and some wire. Every evening, when I was home, I would tell the re-energised little plant, just how clever it was and how beautiful it looked...
...Then one night around mid January, I noticed a tiny red bud. The buds multiplied and started to flower - It took two months for the buds to fully bloom - and now I see there are three new buds preparing for their slow-motion debut.
Give out good vibrations. What works for your pot-plant could work for humanity.
