This bonsai care calendar is specific to the Portland OR area and created by a BSOP member. There are many variables that can affect a tree’s behavior and tolerance, and these suggested timelines provide general guidance and should be adjusted for individual differences such as seasonal variations, micro-climates and the care provided by the hobbyist. 

No guarantees are offered or implied for the efficacy of these guidelines. Special care should definitely be taken if you live outside the Portland, Oregon metropolitan area.
