I bought a bonsai maybe ten days ago. The man who sold it to me said that I should check the soil daily and expect to water it every few days. I bought it on a Friday and watered it on the Sunday; today is the Monday of the following week (so eight days after watering) and the soil is still damp to the touch. What gives? The tree doesn't seem to be in any kind of distress -- in fact it seems to be sending up little shoots from the branch ends -- but I was warned that by the time a bonsai is visibly distressed it's already past saving, so I'm concerned that I'm missing something.
What is going on here?
