Now that you have begun
purchasing your palm trees, this article discusses how to place them
in your garden; including common mistakes, shade problems, space
requirements and other considerations when laying out your garden.
When I first thought
about writing an article on Placement of Palm Trees, I laughed. I
thought, All I need to do is tell about the mistakes Ive made!
You see, here in Southern California land prices are high.
Therefore, most of us are not blessed with expansive gardens.
We must do with the garden space we have. However, we are victims of
palm fever. We are always trying to sneak in another unusual palm.
Therefore, palm enthusiasts gardens can tend to be over-planted.
With time this results in a very crowded garden. Therefore, I must
say for people just starting- do as I say, dont do as Ive done.
If you
are just starting, an important part of your garden and palm tree
care is to have a scheme or plan of what you are doing.
Remember, Haphazard planting gives haphazard results. Unlike other
types of trees, palms are very predictable. You can predict trunk
diameter, crown diameter, and eventual overall height. You also know
whether or not it will have spines, whether it will sucker, and the
cultural requirements. What one must do is give the palm enough
space for what it is going to be, not what it is now or in the near
future. Think ahead. I will discuss multiple topics about palm
placement below.
Giving palms
enough space When growing palm trees, think about
how much space a species will ultimately need. For instance, if you
put in a large species such as Phoenix canaries, give it a lot of
room. Such a plant could easily dominate a 20-foot circumference
area. Likewise, Phoenix reclinata will, in time, form multiple stems
and need a large area. Even a triple Archontophoenix cunninghamiana
needs a fair amount of room. It is true that, when some species have
trunked out and are well overhead, one can add smaller understory
palms near their base. However, if you put a small Chamaedorea
directly next to a Chamaerops humilus, the Chamaedorea will
eventually be lost in the mix. If you cant step back and take a
photograph of a palm in your garden, you have probably planted
things too closely.
Establishing a
canopy of palm trees This is a very important
factor in creating a lush palm garden. Fast growing species such as
Archonotophoenix, Caryota, Syagrus, and some Ravenea will grow fast
and eventually tower over everything else. This is important for
several reasons. It satisfies the enthusiast because he sees
results. It offers shade for species that like less than full sun.
It helps maintain humidity and lowers water requirements. It also
helps create microclimates within your garden, the latter
providing increased humidity, less wind and warmer winter
temperatures. One of our senior Members, Mardi Darian, has said that
creating a canopy is the most important thing a palm grower can
do. He is absolutely right.
Think about sun
and shade requirements Some palms dont like full
sun. Others demand full sun. Proper palm tree care demands
that you do a little research and find out the sun requirements of
any given species. The published Palms for Southern California is an
excellent resource for learning a species sun preference. Also, all
sun is not the same. In Southern California, inland sun is much more
intense than coastal sun. Bismarkia nobilis, Dypsis decaryi,
Chamaerops humilus, Roystonea regia, Acoelorrhaphe wrightii, and
many other species demand full sun. You might keep these species
alive in partial sun, but they will perform better in full sun.
Chamaedorea tepejilote, Chamaedorea ernesti-augustii, and Rhapis
excelsa all do better in filtered light. Most growers will establish
their canopy before planting out their shade-loving species.
Think about the
loss of sun in the future You may have wide open
sun today, but with planting of the fast growing species, your sun
is going to diminish and your palm tree care will suffer.. Plan on
this. In other words, think about where you shade is going to be
when your palms are large. For instance, if you are trying to keep
sun shining on a swimming pool, dont plant canopy-forming species
on the southern side of the pool. Also dont plant a sun-loving
species in an area that you know will eventually be shaded out. I
have lost Dypsis decaryii, Phoenix roebellini, and Aceoelorrhaphe
wrightii in my garden because they got shaded out.
Dont plant too
closely to a structure or walkway In general,
palms do not lift sidewalks nor damage foundations. However, there
is a limit to this statement. A very large species planted inches
away from a houses foundation can cause problems. It is like
trouble waiting to happen. Also consider if the plants crown will
clear the houses eaves. Also, give some distance between your palm
and a walkway or sidewalk. A suckering palm just might crawl right
onto your thoroughfare. Also, never put a spiny palm, especially
Phoenix species, next to an area where people walk or play. Palm
spines can cause serious body injury.
Consider clumping
some species A double, triple or even quadruple
planting of Archonotophoenix is really quite dramatic. Each trunk
nicely curves away from its partners. Such a grouping is also
aesthetic with Roystonea, Howeas, and single trunk Chamaedoreas.
Clumping of individual plants typically does not look good on very
large species, e.g., Phoenix canariensis, Arenga piata,or Caryota
urens. Also, many fan palms are not well suited for clustering.
Dont
just plant pinnate (feather leaf shaped) palm trees
Ive heard many times from new enthusiasts, I dont like fan
palms. Be willing to vary your collection; fan palms look great
with feather palms. Also remember that fan palms are typically
slower growing than pinnate palms. Plant your fans early in the
course of your gardens development so the fan palms can keep up
with your pinnate palms. Be imaginative: use boulders, mounds, or
small walls in your garden to give elevation differences. Strap some
orchids onto your trunked palms. Add some ferns and flowers. All
these things add to the charm of your garden.
Preserve and
accent your views Be selective in planting your
palms so you can maintain views around your home. Preserve panoramic
views by planting less obstructive palms, i.e., smaller and thinner
palms. To preserve views for observing your garden, allow space
between plants and avoid clumping palms near your vantage point.
Rather, utilize clumping palms to hide unsightly fences or walls.
Some people prefer to stair-step plantings; smaller closer up front,
larger in the rear. However, this is up to your own aesthetics. You
can accent an entrance or courtyard with colorful or lush species of
palms. Remember views are important as they affect the way you and
others look at your yard. Think about the ideal planting for your
yard.
Consider specific needs Proper palm tree care
demands that you know that different palms require a wide variety of
conditions; so, it is important to know what your conditions are and
what any given species prefers. Soil type, high and low
temperatures, wind, etc., are some of the important factors to
consider when you plant your garden. Sun requirements should
be known before planting palm trees into the ground.
What plants should you grow? These are all things that you can
learn from references or by talking to people in the Palm Society.
Oceanfront gardens, hot inland gardens, arid gardens, and windy
gardens all have their own specific conditions and preferable palm
species. Within your garden itself, there also may exist different
microclimates. You may have wet areas. You may have dry soil areas.
Take advantage of this and plant species specific to each
microclimate. Research will lead you to the right palms.
Dont
overdo any given species Be experimental in what
you plant. Mix species, textures, types, and looks when growing palm
trees. Importantly, try to avoid planting too many of one species
just because you got a good deal. The latter will lead to a boring
garden. I once knew a man who planted one hundred Queen Palms in his
front yard. He said he got a good price and thought hed make some
money by digging them up later. He planted them all in rows.
Needless to say, it was the worst landscape job I have ever seen.
Eventually he lost money because he had to pay tree-removers to
correct his mistake. Remember the saying that more may not be
better. Its also more fun to expand your collection. One exception
to repetitive plantings might be along a parkway or along a
driveway. In these locations repeating Royals or King Palms look
very nice.
Remember to
acclimate your palms Make sure your palms are
acclimated to your area and your sun before planting palm trees. If
a plant is coming from a greenhouse or filtered light, gradual
acclimate it to full sun over a few months. Alternatively, one can
use temporary overhead shade structures for protection while growing
your palm trees before planting. Remember to water thoroughly
after planting a new palm. If you are craning in large specimens,
you can get some instant shade for under-story palms. Take advantage
of it.
Summary:
Every garden and every palm enthusiasts viewpoints are
different. However, above are some agreed upon concepts. If you
follow them, you will perhaps avoid some of the mistakes I made. So,
you might ask what did I do wrong when I planted my garden. The
answer; lots of things! I lost sun-loving plants that got shaded
out. I planted pigmy date palms next to a pathway. I burned species
with too much sun. I have an over-abundance of King Palms. And
finally, over-planting has definitely visited my garden.
