Understanding Tree Categorisation

One of the ways we navigate how to understand a trees physiological processes is to define certain trees into a number of categories. Our method works with two major categories and a number of sub categories.

  • Elongating

    • Scale Junipers

    • Pines

    • Casuarina

  • Broadleaf

    • Broadleaf-evergreen

    • Deciduous

    • Tropical

 

Elongating

Elongating species defines those trees species that in the Spring create a highly phototropic elongating piece of growth. This is usually a single flush or a high degree of discrepancy in the strength of the Spring flush and subsequent flushes. Metabolisms will be high and growth strong for Elongating species. IN order to harness the mighty strength of Elongating species requires precise Spring techniques for management and perpetuation of growth management and wire as a major tool for design. For the majority Elongating Specie almost entirely are made up of Confiners.

Australian Native:

  • Callitris sp.

  • Mt Spurgeon Pine

  • Araucaria sp.

  • Podocarpus sp.

  • Pencil Pines

  • Huon Pine

  • Casuarina & Allocasuarina

Exotic species:

  • Spruce

  • Hemlock

  • Fir

  • Redwood

  • Cedar

  • Cypress

  • Single-flush Pine

Elongating Species Sub-categories

You May notice in our schedule of classes some times Junipers & Pines are included in Elongating focused classes and at other times they are separated, although these two genus behave inside of the guidelines for Elongating they have their own specific nuances that require different attentions when handling.

 

Junipers - specifically Scale junipers

This unique Genus of plants having a foliage mass that is neither leaf nor needle curiously has an adventitious growth pattern in which enables it to slowly, but perpetually grow. This adaptation if handled correctly makes for an excellent Bonsai subject and hence their historical popularity. Handling the foliage correctly is paramount to their success and usually divides our time into Juniper times and Juniper hands off times.

  • All Juniper species

    excluding the needle junipers - Junipers rigida & Juniperus Communis (Strictly Elongating)

 

Pines - Specifically Multi-flush pines

The Primary nuance of Multi-Flush Pines is the ability to entirely remove the new seasons growth as a mechanism to trigger energy dilution into a second flush. This is a unique ability not shared among other Elongating species.

  • Japanese Black Pine

  • Japanese Red Pine

  • Monterey Pine



Broadleaf

Broadleaf trees are characterised simply by having a ‘broad-leaf’ this is relative and some broadleaf trees have extremely tiny leaves that are narrow. Though this does not change the functionality of that broadleaf.

A Broadleaf tree has an efficient solar panel and is able to produce very abundant amounts of resources from this system. Understanding this mechanism enables us to use this solar panel to control and allocate sugars often multiple times a season.

To understand broadleaves there are a number of ways to devide the Broadleaf world to gain firther control over this genre;

Broadleaf-evergreen

Broadleaf-evergreen simply implies that it is a broadleaf tree that holds its leaves all season. This means these trees have the opportunity to photosynthesis all year round.

Exotic:

  • Eleagnus

  • Evergreen Oaks

  • Contoneaster

  • Pomegranite

  • Irish Strawberry

  • Olive

Australian Native:

  • Eucalyptus

  • Kunzea

  • Leptospermum

  • Melaleuca

  • Syzigium

  • Banksia

  • Ficus

  • Nothofagus

 

Deciduous

Deciduous are trees that will expire their leaves for the turning of the season. Be this for Winter dormancy or for someTropical species, a summer dormancy. Deciduous trees are almost always are Broadleaf trees except for a few outlying Confers, that although loose their leaves still need to be treated physiologically as Conifers and subsequently moves them to the Elongating genre.

To understand Deciduous Broadleaf tree is to understand that comparatively to Broadleaf-evergreen Deciduous Broaldeaved ahve aperid of the ear that the are not photosynthesising which dramatically chanegs the way they interect with th growign season.

Exotic:

  • Maple

  • Beech

  • Stewertia

  • Hornbeam

  • Elm

  • Prunus

Australian Native:

  • Nothofagus Gunii

  • Toona




 

Tropical

Tropical trees aost alwsy are Broadleaf trees. As mentioned above, some Tropcal trees wull also finction as deciduous during hte summer. The differnetiating factor between Tropical and our other two subctaagories of Broadleaf is the ability to metabolicaly finction efficiently at higher temperatures and have less a functionality at lower temoeratires. So Woring with Tropcal-broadleaves ingoverned by temperature ranges and how much can be acieved in that period allocated dring the growign season.

Exotic:

  • Ficus

  • Buttonwood

Australian Native:

  • Ficus

  • Brachychiton

 

Large-leaf Broadleaf

Large-leaf Broadleaves are characterised via relatively large leaves that generate a great deal of photosynthetic surface area per internodal zone. The internodal potentila is less than that of a small-leaf broadleaves and as such control of the indiviudal solar panel or leaf is pivotoal to energy diluation and maximisjng internodal sites for diltuon of ramifiaction.

Eg. Ficus, Maples

Small-Leaf Broadleaf

Small leaf Broadleaf is defined by the size of leaf being small. When leaves are naturally small there is a relatively smaller size and more numerous quantity of internodes allowing for greater inter-nodal potential. The priorty of Smal-leaf broaldeaves is not to control growth via the indvudal manipulation of leaves but rather by the reduction of potetnial interodnodes to dilute disperse enrgy.

eg. Olive, Kunzea, Melaeuca, Elms
