Summer Outdoor
Our trees spend most of their lives outdoors. The
growing area is where we see them the most - where they
get their daily attention for most of the year. This is
usually where others see them the most. Thus it is nice to
have a pleasing display. Display areas can range from a
table on an apartment balcony for a couple trees to a yard
full of trees to elegant bonsai gardens. The most common
approach for those with yards is to keep our bonsai on
benches at a level convenient for maintenance and for
viewing. The benches might be on a deck as shown in the
snow. In a more rural area, the collection might be kept
inside a fence to minimize deer brousing. A bonsai
garden is shown from above in the picture to the left
The benches can be supported on concrete blocks,
posts sunk in the ground, or terracotta chimney flues.
Pressure treated wood or cypress wood will last longer
than normal lumber.
There are several more elegant approaches to display,
but they entail greater space between trees, thereby
allowing undistracted viewing of any
given tree. The one shown first is to
provide neutral backgounds behind the
trees. This will often be a stucco wall.
Benches thicker than standard 2x12’s add
drama. These types of displays can bee
seen at the National Arboretum or
Weyerhaeuser’s Pacific Rim Bonsai
Collection. The other elegant approach is
to show the trees on individual posts set in
the ground and topped with wooden platforms or as shown
below, concrete disks. While very elegant, this approach
requires lots of pre-planning and hard labor and will take
longer periods of time for watering. It also requires lots of
open space in an elegant setting to pull off well, though I
have seen it pulled off well in a small yard surrounded by
a high cedar fence.
Winter Storage
While it would be nice to display all of our trees year-
round, it is not practical in the mid-Atlantic where
temperatures pass thru freezing about 60 times per winter. Those temperature transitionsed are hard on pots and roots.
Thus, most of us have some provision for winter storage of trees. For a couple trees on an apartment balcony, the
protection can be as simple as placing the trees under a table with plastic draping for protection from the wind. Other
methods for smaller collections include enclosed breezeways or on the steps under a Bilco door to the basement.
For larger collections, once can construct cold-frames such as those shown to the left. These are topped with clear
plastic and can be openned on sunny days so that temperatures do not get too high. The trees are placed on the bottom
of the cold frame with no protection until themperaturee have gotten low enough for mice to find their winter homes.
After the threat of mice is over, the root of the trees should be covered with mulch for additional thermal protection.
Another method of winter protection is to
store trees in an unheated garage as shown
below. The trees are well protected. Trees that
come out of winter dormancy early (quince,
larch, maples and crab apples) should be stored
low and close to the garage doors while more
sensitive trees (Chinese elms and crepe myrtles)
should be stored high and closer to the house.
Cold greenhouses are an option for more
professional growers. And in
the Pennsylvania and
Delaware areas, old spring
houses provide an ideal
environment. One of our
members has a concrete block
shed set into a hillside such
that it is largely below ground
level. A 55 gallon drum of
water provides moisture and
thermal ballast - a wonderful
solution available to few.
