What is it about rainwater?
I get that in heavy or persistent rain, the ground gets well soaked and there's plenty of moisture for your plants.
However...... How is it that after a good soaking of rain, potted plants that you've been keeping watered make a growth spurt?
For example, I bought a tray of mixed verbena, cheap. I decided to pot them up until I could see what colour they were going to be. We had apocalyptic rain and hail this afternoon and when I looked out this evening, they were about twice the size. Is there something in the rain or is it the humidity?
