maintenance schedule

 

Things to do

Please note that this schedule should be taken as general advice only and must NOT be used as a substitute for expert advice.  Seek advice for specific plant species and local climatic conditions.

 

 September

Most, but not all bonsai begin their growth this month with typical weather conditions and consequently require more care and attention, particularly with the possibility of weather extremes. Partial shade may be better to avoid the possibility of leaf burn.

 

 October

Similar to September but the growth cycle is more advanced. The tree healing process is most efficient.

 

 November

Too much sun can dry out the leaves and turn them brown.  Filtered sunlight may be better for tender leaved trees.  Mildew can start to form.

 

 December

Similar to November.  Do not over fertilise or over-water.

 

 January

Heat can be extreme.  Avoid watering during hot sun, and water only at morning or evening - never late at night.  Protect plants as needed.

 

 February

The growth cycle can start to slow down.  Pruning should be selective and light.  Check brittleness of branches before shaping.  Check to see if pots are draining properly.

 

 March

Continue to protect leaves from sun burn. Slightly trim new bonsai still in the growth cycle, after shoots have matured. New bonsai can also receive half strength fertilising.  At the end of the month deciduous trees can be transplanted from one pot to another if only light root pruning is required.

 

 April

Partial shade may be better to avoid the possibility of leaf burn.  Prepare for the coming winter and care is required with the possibility of weather extremes.  The possibility of early frost means some bonsai may need to be protected.   Deciduous trees can be transplanted with root pruning.  Remove tight wire and trim shape on deciduous trees.  Trim strong growth on conifers and pines.

 

 May

Less water required , but do not let trees dry out even though dormant.  Check on pot drainage.  Never water when frozen.  Most branches are too brittle to wire. Protect from severe cold weather.

 

 June

Watering should continue as for May. Trim plants with care.  Trees are dormant in the  coldest months and it is the best time to attempt grafting.

 

 July

Trees should still receive a little time every day.  Water every second day.  Study the structural lines and form of deciduous trees.  Shaping and trimming should be done with care as branches may be brittle.  Tropical or semi-tropical trees should be protected in a green house or under a tree with thick foliage.  Take care to protect from frost.  The best time to attempt grafting.   Spray deciduous trees.  No fertiliser.

 

 August

Water every second day.  Shaping and trimming should be done with care as branches may be brittle.  Tropical or semi-tropical trees should be protected in a green house or under a tree with thick foliage.  Take care to protect from frost.  If a deciduous tree starts sprouting and/or blossoming it should be brought out of the shade. Watch out for the start of aphids.  Fruit bearing trees can be pruned after they have blossomed.  Early in the month, check growth on azaleas and camellias to see if they are ready to transplant or re-pot.
