FAQ'S
About The Sago Palm
-
“Do
I have a Sago Palm?”
The best way to tell this is to look at
photographs of Cycas revoluta
and see if that is your plant. There are other species of Cycas that
look similar to the Sago, but this species is easily identified once
you become familiar with it. If it looks like the photos of a
Sago Palm and you didn’t actively seek out a rare species when you
bought it, the chances are that you have a Sago Palm. If you bought a
new property and it happens to have a cycad in the garden, and it
looks like a Sago, the chances are once again that it is a Sago Palm.
Other species are more rare, but there’s always a chance that it
could be something different. Look at our Cycad Photo Gallery.
That might help you determine this.

“How
fast does a Sago Palm grow?”
The answer to this
question depends on where you live, how much sun it gets, and overall
culture. This species is much faster growing in tropical areas of the
world. Contrast this to a plant that is being root restricted in a
small container, and one sees a whole gradient of growth rates.
However, under most conditions, the Sago Palm is a good grower. It can
put on a foot of trunk in eight to ten years. Typically plants will
not cone until they are over ten years, sometimes much longer. If you
live in our locality in California, a plant that has three to four
feet of trunk is typically about 20 years of age or older.
-
“Can I dig and move my Sago?”
The answer is yes. One would preferably
dig a very large rootball, giving ample distance from the trunk. This
would optimally be done during the Spring or Summer. Care should be taken
not to cut through any sizeable roots (greater than one inch) or rot could
set in. It is also advised to remove a good portion of the leaves before
attempting to relocate the plant, especially if a smaller than desirable
rootball is unavoidable. Water it adequately after moving, making sure not
to over-water the plant. The Sago Palm is quite durable. As a nurseryman,
it is quite easy to reestablish plants that have had all of their leaves
and roots removed. But, common sense would lead you to avoid damage to
existing roots if possible.

“Can I remove the babies on my Sago Palm?”
Yes. It is best not to
remove the basal suckers until they are at least 10 to 15 cm in diameter.
We recommend removing most or all of the leaves. Clean equipment must be
used. The sucker is removed at its base, without scaring or damaging the
mother trunk. This is best done with a somewhat curved saw blade or a
sharp chisel. Protect the mother trunk by moving dirt away from the point
of attachment and letting it callus over for a few weeks after removal of
the offset. Many people will treat the cut surface of both the offset and
mother plant with a fungicide and some type of sealing material such as
tar or wax. The removed offset can also be treated with growth stimulants.
It should be place in the shade in a rapidly draining mix. We prefer to
use pumice (ground lava foam), although people often use sand, perlite, or
other materials. Water just to keep the pumice slightly damp. Avoid
watering the offset; rather water the soil. The pup should root out and
leaf within six to twelve months. Failure will be discovered if the offset
collapses or becomes very soft on squeezing. Once rooted and leafed,
gradually move the young plant can be repotted into a regular cycad soil
and moved into brighter light. A greenhouse environment may speed up this
propagation process. Bottom heat is usually not necessary, but can be
used.

“Can I grow plants from my seeds?”
The answer to this
depends on
whether or not you have fertile seeds. Did the cone get pollinated?
Remember, females can produce seeds that look good but are infertile and
will never germinate. If you have a male that is coning, the pollen can be
collected from the male and put into the female cone. This can be done dry
or with a solution of pollen. Multiple attempt should be done to pollinate
a receptive female. If you do have fertile seeds, the red fruit should be
removed and the seeds allowed to dry and age for about three or four
months. One can actually cut open these aged seeds and look for a maturing
embryo inside the seed. It will appear as a ribbon like structure or a
cream colored band in the center of the seed when the seed is cut on a
longitudinal basis (along the long axis of the seed). As the seed matures,
this embryo starts extending toward the end of the seed where it will
eventually emerge. To germinate cycad seeds, most growers utilize bottom
heat or a greenhouse. However, this is not mandatory. Use a well draining
mix like a peat moss/perlite mixture and water about every third day.
Frequent misting is not necessary. When the seed has established and put
up one firm, opened leaf, the seedling can be removed from the germination
mix and potted into a small container.

“Do I have a male or female
plant?”
You can only tell if your plant is
a male or female when the plant is or has shown its reproductive cones. In
many types of cycads, the male cone looks like a yellow-cream colored corn cob
and the female looks more like a
cabbage head. When ready, the male cone will dump
out a powder like white substance called pollen. This pollen needs to be
transferred to the female cone. The female cone is usually larger than the
male, especially after it has been pollinated and is setting seeds.
However, with the Sago Palm and other Cycas species, the female cones
appear different. It does not look like a pineapple. It emerges from the
central area of the crown and sort of look like a round mass of twisted
and compacted tiny leaves. You might say it looks like the plant is having
a “bad hair day”. The female sporophylls (reproductive parts) of this
reproductive part are cream colored and circular. The male cone is
upright, somewhat bristly, and looks like a long rough torpedo. Pollen is
released from the male and is transferred to the female when receptive.
When receptive, the female can be seen to open up slightly between the
many sporophylls. Sagos typically cone during the Spring or Summer. If a
plant cones, it might not put out new leaves that year. Also, it is not
unusual for the leaves of a female plant to lay down in a near horizontal
plane when the female plant blossoms. Even if the plant is not actively in
blossom, one can often tell if it’s a female because of the frilly
sporophylls that lay down on the upper outer side of the trunk near the
leaves (see photos). Or, you might see an old brown male cone laying on
it’s side inside the crown of leaves, showing that you have a male
plant.

“Are the seeds on my Sago Palm good?”
If you have a male plant nearby
and you live in the tropics, it is possible that insects could have
transferred pollen to your female. But, if there are no male Cycas nearby
and you didn’t artificially pollinate the cone, then the chances are
that your seeds are no good. Infertile seeds won’t show an embryo inside
when you cut open the seeds. They also will often have an empty central
cavity (where the embryo should be) and consequently float in water. It is
possible for some Cycas seeds to float and still be good, but ideally your
seeds will sink in water.

“When can I pick my Sago Palm seeds?”
Do not harvest your seeds if
they are not mature. As the seeds form, they increase in size and change
from a cream or yellow color into a bright orange color. Mature seeds will
turn a colorful orange color, are somewhat hairy, and are mixed among the
female sporophylls. It is best to collect them when they fall on their own
from the sporophylls or can be removed with a minimal touch of the seeds.
Sometimes the seeds will actually get hung up inside of the female blossom
and must be coaxed out with an instrument. If you have to “yank” them
off the blossom, it is best to wait until they can be removed easily.
Remember to clean off the fruit, allow them to dry, and store them for
several months (in a sock or woman’s nylon for ventilation) as this type
of cycad has an “after-ripening period” that is needed before the
seeds will germinate. The fruit is firmly attached initially. One can soak
the seeds for several days (changing the water daily) to soften up the
fruit. Typically it can be removed with a knife or other implement. After
you store the seeds for a few months, hydrate them with a 24 hour clean
water soak before potting them up.

“How do I germinate my seeds?”
After storing and
hydrating the seeds
as above, place them on their side in your growing medium. We usually use
about three parts perlite to one part peat moss and put many seeds into
one container (a community pot). One can use other mediums including sand
if you wish. Although not space efficient, you could place one seed into a
tiny pot for initial germination. The seeds should be submerged about half
their depth into the soil mix. Place the container in the shade in a warm
location. One can use a greenhouse to get faster results. Water to keep
the mix damp. Don’t over water. The seeds will germinate out of the end
of the seed, first showing a growing radical (tap root) which will go down
into the mix. Following this by a month or two will be the leaf. It is
quite fragile when young and can break if handled roughly. Once this leaf
is firm, the seedling can be carefully removed from the germination
container and potted up individually.

“My Sago Palm hasn’t put out leaves for several years. What’s
wrong?”
Failure to put out new leaves can be from many causes. Perhaps
your plant is not in enough sun or your locality is too cold for good
growth. It could be that there is an unrecognized root problem or rot. It
could be the plant is nutritionally starved. Or, the plant may be getting
ready to put out its reproductive cone. We usually recommend correcting
cultural problems and giving the plant time. Most plants grown well will
eventually put out new leaves.
-
“The leaves on my Sago Palm look bad. What’s the problem?”
This is a
complicated question. You might want to read our article “My cycad is in
trouble”, elsewhere at this website. The plant might be stealing
nutrition from the old leaves in preparation for production of new leaves.
Or, you may have a cultural problem. If you have total discoloration of
the leaves, check the caudex or stem. Is it firm and hard? Or, is it
getting soft or mushy. The latter almost guarantees that the plant will
die. If there’s just a big of brown tipping on the ends of the leaflets,
this can mean a lack of fertilizer or can appear before the plant throws
new leaves. We recommend fertilizing the plant and waiting. If the problem
is new leaves are coming, time will explain the observed leaf
discoloration. If no new leaves appear for a year or more, your problem is
probably some type of cultural deficit.

“Are there other types of Sago Palms?”
The answer is a definite yes!
We do sell Sago Palms, but our real love is for the whole family of
cycads. We are presently growing over 150 species or varieties of cycads.
There are over twice that many that are known to exist somewhere on this
planet. Cycads vary in size; some are quite small, others get massive. The
colors of the leaves are quite variable; some are green, others gray, and
some as blue as the morning sky. Some a prickly, others soft and
touchable. Some are quick growing; others are slow and never get big. Some
like sun, others like protection and shade. Some like tropical conditions;
others like it hot and dry. As long as your area doesn’t get really
cold, there is probably a species of cycad you can grow. Cycads are truly
a remarkable group of plants and great for any landscape areas. But, I
must warn you of one thing. Cycads are addictive. Once you get hooked on
them, they are like the lure of a beautiful orchid. You just want to try a
few more. Look in our Cycad Photo Gallery and you will see why cycads are
becoming on of the fastest growing collector and landscape plants.
