Overwatering
From BonsaiWIKI
Overwatering is problematic for most species. Oaks and Pines are particularly subject to root rot.
Needles and leaves will yellow and fall. Other trees will suffer from a loss of oxygen in the bonsai soil.
Overwatering can cause putrefaction of the bonsai soil, encourage the growth of hornwort and fungi. Other trees, like Bald Cypress, Wisteria and willow are notable exceptions to this rule and have high water demands during the summer. Throughout the summer we place our wisteria bonsais' pots in a saucer with an inch or two of water available at all times.
