Check soil moisture daily by pressing a finger into the top layer rather than watering on a fixed schedule, since a bonsai's shallow pot dries out far faster than a regular potted plant and both underwatering and overwatering can kill the tree within days. Water thoroughly until it drains from the pot's bottom holes rather than giving a light splash, since shallow watering only wets the top layer of soil and leaves the deeper roots dry even though the surface looks moist. Prune and wire branches only during the tree's appropriate season, since cutting or bending at the wrong time of year can shock a tree that's actively growing or damage bark that's brittle during dormancy. Remove wire before it cuts into the bark as the branch thickens, since wire left on too long leaves permanent scars that can take years to grow out. Repot on a species-appropriate cycle, generally every one to five years depending on the tree, rather than leaving it in the same soil indefinitely, since old, compacted soil eventually stops draining properly and slowly suffocates the roots. Keep the species' specific light and temperature needs in mind rather than treating all bonsai the same, since some species need to experience an outdoor winter to survive long-term while others must stay indoors year-round.
