Monthly Care (First Quarter)

January can have many rainy days and snow is also possible. The most important thing to do this month is to make sure that bonsai are not standing in water. Tip the pot to ensure drainage. Bonsai need to be protected from cold winds. A simple thing to do is to cover the trees with plastic sheeting on the coldest nights and windy days. Do not fertilize or do any transplanting. Indoor bonsai may need extra lighting. Be sure the trees are not too close to heat sources or drafty windows. Fertilize indoor trees once a month during the Winter.

February is the beginning of early Spring in the Willamette Valley. Camellias and snowdrops are blooming and some deciduous trees may start to show buds. If any of these are scheduled for repotting, this is the time to do so. Wiring can also be done (before repotting) but care should be taken not to break any buds! Do not fertilize deciduous bonsai; evergreens that are not scheduled for repotting may be fed lightly.

March begins the advent of some warm sunny days but rain is still prevalent and snow can still occur, though infrequently. All deciduous bonsai should be root pruned and repotted during this month. Conifers can be wired, but take care not to wrap needles. Conifers, camellias, rhododendrons, and azaleas can be root pruned and transferred from the ground into pots. Grafting should be done this month. Light fertilization can also take place (10-15-10)
