Trimming Bonsai
There are two types of trees, conifer and deciduous.
Everything about deciduous is fast. Fast growth, fast to regrow, fast to drop a branch if stressed, fast to take the shape of wire. I have the following advice for these trees. 1) leave extra branches on these plants. 2) protect them from winter cold, and from drought.
Conifer trees (pine, hemlock, yew, boxwood, cedar) grow much slower. But, conifers tend to be tougher and more hardy plants.
There are three main types of Bonsai Trimming. Scaly plants, needle plants and leafy plants.
1: if the plant is scaly like a juniper, sequoia, chamecypress, thuja/cedar, or some heather, then you let it grow. These plants tend to form compact foliage clusters which can be shaped every couple years to increase structure. Trim off long growing shoots down to the rest of the foliage mass.
2: if the plant has needles that come from a growth candle (spike with no needles or leaves) or one that has a leaf or needle every couple millimeters, then one needs only snip the candle or branch at 1/3 its size, during the growing season when it slows down enlarging.
3: everything else has leaves. Maple, rosemary, escallonia, boxwood, thyme, and fushia are some examples. Cut the growing branch off leaving at two leaves on the new branch, not including the leaf the branch came out of - if there is one. If the branch still sticks out a lot, cut the branch to one leaf. Do not do this after September.

Eventually, your bonsai will get bigger. Think about it - five years of trimming at 2 branch nodes, twice a year or more. This means your tree will grow by 20 branch nodes in five years!
Some of this will be good for the tree. As the branches become smaller and more plentiful, your tree will look like it is a more mature tree. Some growth from the original size of your bonsai is great for the look of the plant.
Some of this will not be good for the tree, the branching will make the plant look like a shrub. There a few types of trimming to be done to prevent ones tree from becoming a shrubby mess.
1: pluck clean the branches and twigs growing from the trunk or base of the larger branches. These will only conceal the beautiful trunk and branching of your bonsai.
2: as the tiny end twigs become more numerous, try to eliminate some of the larger branches. One can use the excess twigs from a still attached branch to hide the spot where the other branch has now vacated. The reason one does this is to encourage taper and movement; and to simplify the tree in a zen sort of way. This also can help to reduce the overall size of the tree.
