Some locations experience two growing seasons where summer dormancy is indicated by mature terminal leaves. At the end of this semi dormancy, terminal buds begin to enlarge but before the new leaf unfurls. This is the better way to explain the correct time for root-pruning rather than using seasonable terminology.
Within the Sydney region on roughly latitude 33 deg. S. the correct timing for pruning the roots of many plants is late summer & late winter repotting. This can still mislead as we have three varying degrees of temperatures in the greater metropolitan area, enough to make it slightly unsafe for some if we all repot on a given date.
Many people sill repot in autumn ie. April, May. but may run into difficulty if the temps. fall dramatically before the roots have time to regenerate. As well we have some species that prefer to be root-pruned at the height of summer where they require continuing high temperatures to enable stress-free regeneration.
The weather in Sydney has been unpredictable lately, making it difficult to know whether it will be safe to proceed with late summer root pruning. The determining factor for success is the guarantee of temp. stability.
Regeneration will still take place where a slight increase in the spring and slight decrease in the autumn night temperatures for several weeks after The object of this tip is to allow your plant to inform you when it is ready for its 'little operation'.
The bonsai guidelines were created in order to help enthusiasts to be able to style their plants to obtain an artistic arrangement of the plant’s structure.
This can be most helpful for those who are not naturally artistic. Some aspiring artists labour at styling; not knowing which way to go and getting nowhere. Conversely, others not knowing the guidelines create very creditable bonsai.
These people have a natural instinct for the beauty of line, the balance of space and mass, stability and direction. Some of the best landscape artists are self-taught, balancing mass and space effectively.
