This Japanese white pine won the Prime Minister's Award at the 2005 Sakufu Ten Bonsai Exhibition. Though it has nothing more to do with watering than any other bonsai, the photo is from Michael Hagedorn's Crataegus Bonsai, as is the text below.
Yet Another Watering Problem…
The following is by Michael Hagedorn from his website Crataegus Bonsai.
“Probably the worst thing we might encounter when we have a hose in our hand is a tree that, when we think about it, has not dried out in three days of sunny summer weather. That ought to send off all kinds of alarm bells in your head. If none go off, install some.
“First of all, don’t water the tree if you want it to live. Secondly, place it in semi-shade and mist it frequently. The roots are not working, they are not drawing up moisture. Usually what has happened is root rot: the small roots got crispy dry, then they got waterlogged, and now the soil is staying waterlogged and everything that was living is slowly decomposing. This is like a heart that just stopped pumping and the medics are scrambling for the jump-start. If those small rootlets don’t start growing out again soon, the tree will die.
“Tip the pot up on a block to let the excess water run out the bottom of it. The pot must be kept a bit on the dry side, and water introduced by misting onto the leaves to get the tree going again.
“This is one of those cases where prevention is worth it’s weight in platinum. Don’t let your trees get COMPLETELY dry, and be ever alert to those that are not drying out as you would expect.
