Caring for
your Plumeria:
Plumeria (also known as frangipani) grow to be large flowering trees in the
tropics. The blooms are beautiful and have an intoxicating fragrance. Since
plumeria are so easy to grow, and they have a plethora of fragrances, and
there are such a dizzying array of color combinations they can get to be
addicting? Soon you'll find your house, garage and greenhouse full of these
beautiful tropical plants. Plumeria go into a natural dormant period, so it
is easy to grow them in containers and bring them inside for winter storage.
While dormant, Plumeria do not need to be watered at all.
Plumeria are very adaptable. They can be grown in containers, in the ground,
or you can use the plunging method (sinking containers into the ground).
During their growth season, your plant will require lots of sun, water and
fertilizer to thrive. When your plumeria gets at least six hours of full sun
per day, it will delight you with lots of sweet smelling, beautiful blooms.
This plant feeds heavily and will grow and bloom vigorously if you give it
plenty of its favorite fertilizer. Plumeria also love water, but they can't
stand to have wet roots. Be sure and plant your cutting in fast draining
soil or make sure it has adequate drainage. In tropical areas, plumeria can
grow up to 20 feet high and 20 feet in diameter… but you can control the
size of your plumeria plant by the size of container you choose for it.
Light:
Plumerias love full sun! However, if your plant has been shaded for awhile,
such as in the house, do not just plunk it down in the middle of yard. Move
it gradually so it can adjust to the strong rays of the sun to avoid
'sunburn'. Stems that have been stored for the winter need this same gradual
care. In order to bloom, your Plumeria will require a lot of sun. They prefer
bright, airy spots like sunny greenhouses with good ventilation, or a front
walkway that catches the early morning sun into the afternoon. If your
succulents and cactus like the spot, so will your Plumeria.
If you would like to keep you plants growing even during the winter, consider
growing Plumeria with florescent lighting.
Water:
When watering your Plumeria just use common since. If the dirt is dry give
the plant some water. If the dirt is moist, skip the water this time and
wait until tomorrow. The most important thing to remember with plumeria is
they don't like 'wet feet', don't let the soil become soggy. This has a lot
to do with the makeup of the soil. If you are just starting out with a
cutting, plant the Plumie in the soil and wet thoroughly, do not water again
until you have 4 or five well formed leaves. You can mist the tips every couple of
days if it is very warm and dry out. Once you have 4 or 5, 2-3 inch leaves,
then water once per week for the next month.
The same goes for a rooted Plumeria
that you may have purchased, except for the fact that you can lightly water
the plant once a week until a few well formed leaves begin to grow. After
that, water and fertilize as needed. When the time comes for the plant to go
dormant, these rules go out the window (see dormant Plumerias below). The only time the plant should be
completely dry is in the winter when it has entered this dormant period.
Temperature:
Remember, Plumeria grow in the tropics! Make sure they are kept at
temperatures above 50 degrees Fahrenheit at all times. Once established,
they can tolerate occasional drops to around freezing for very short periods. Frost
will kill the ends and cause a delay in your next bloom. Exposure to freezing temperatures
for longer than a few hours will kill your Plumeria.
As for high temperatures, as long as they have good ventilation, they can do
very well on very hot days. Here in Atlanta I have noticed that the hotter
it is, the happier my Plumeria are. I just have to water every day. Plumeria
need warmth, so if you live in a cool climate, you may want to grow them in
a greenhouse for the best results. For peak growing day time temps should be in the 80s
and 90s while nights should be in the mid 60s to 70s.
Fertilizer:
As mentioned before, Plumerias need a lot of food. Fertilization should be
applied by liquid or time release methods or by spraying the leaves weekly
with a mix of fertilizer. Don't worry about adding soil mix that contains
fertilizer such as Mircle Grow or other plant soil mixes or manure. These do
not have the proper drainage needed and will become soggy and are slow to
filter the water. Let your plant get its food through the water you give it.
If you love to pamper your plant and wish to mix up your own batch of
water/fertilizer mix, it is currently recommended that you use a high
phosphorus (middle number) water soluble mix such as a 'super bloom' type fertilizer
(10-50-10). In this way you can accurately measure the amount of fertilizer
your plant gets each time you feed it. Feeding the plant every other week
will promote healthy branching and most importantly, lots of new blooms. The
secret to lots of blooms is lots of branching. Each tip on your Plumeria
will produce a flower stock or 'inflo' which in turn causes that part of the
plant to branch 3 or 4 times. Now each of those 3 or 4 braches will
eventually flower and create multiple branches on each of those tips. The
goal is to get your plant to flower (for the beautiful fragrant flowers) as much as
possible which in turn creates many more flowering opportunities as the
tree grows. A fertilizer high in phosphorous will greatly aid your plant in
this flowering/branching process. If you are a busy person that does not
have time to mix up your own batches of fertilizer or if you are afraid you
will forget to feed it regularly, you can buy a time released, pellet type
fertilizer that will feed your plant on a regular basis. Again, be sure to
get a high middle number fertilizer. For those of you who really want to rev
up the flower-ability of your Plumie is to supplement the water/fertilizer
feedings with a foliation fertilizer spray. Plants can make much better use
of fertilizer sprayed directly on the leaves as opposed to being added to
the soil. A mix of SNG, a 10-10-10 fertilizer and Coco Wet can a super
booster to your growing periods. Once Spring and Summer have passed and
September roll around it is time to stop the fertilizer feeding and prepare
your plant for dormancy.
Dormant Plumerias:
Once the falls arrives and the days shorten, your Plumeria will begin to go
dormant. During this time flowering will cease and some if not all of the
leaves on your tree will turn yellow and fall off. At this time you should
gradually stop watering the plant until you no longer water it at all.
During this time of dormancy, if winter temps will fall below freezing, you can bring
your potted tree into the house or garage for storage until the next spring.
Some people even take the Plumeria out of the soil, wash off the roots and
hang it from the rafters or put it in the attic. Just be careful not to
break off the roots. As you can see, the Plumeria is almost dead during this
time. But once the temps begin to get back into the upper 50s at night and
70s during the day, you can bring your Plumeria back outside again
(gradually moving from shade to sun) and its flower time again. This aspect
of the Plumeria really makes it an easy plant to grow and take care of. Do
not fertilize or water your plant from around September until it has put on
4 or 5 well formed leaves in the spring. Some people will give a light
watering once a month during the winter.
Soil:
Plumerias require a soil that promotes good drainage. A good mix would be
1/3 sand, 1/3 perilite, and 1/3 bark compost or peat. A bag of cactus mix
will also do well. Even a mix of 50% sand and 50% soil mix will do.
Repotting:
After the first year or two, that 8-10 inch pot your Plumeria started in
will be too small to sustain vigorous growth. A 12-14 inch or even larger
pot will sustain your Plumeria for the next few years. Replant your Plumeria
so the stem is at the same level as before. Sometimes you can skip the
repotting and just top up your soil. To do this, remove some of the soil off
the top of the pot and add fresh mix. You can alternate this with repotting.
Pruning the fine roots each spring is beneficial to the plant. The fine
roots from the year before will die during the winter. These old roots take
a long time to decompose, and may clog your pot. If you prune the roots, you
can put fresh soil around the larger roots for several years, keeping the
same pot. Just fill the space the old fine roots took up with fresh soil. Be
sure to monitor your root system. The key to a healthy Plumeria is a healthy
root system. Once the root system has filled the pot, it is best to move up
a pot size to allow your plant to expand. This will promote a healthy trunk
which needs a growing root stock to promote its growth. Without a healthy,
growing trunk it will be difficult for your plant to support its ever
branching and growing top.
Winter protection:
Once the temperatures begin to fall into the 40s, bring your Plumeria
indoors. Water them before you bring them in. You should not need to give
them water very often, if at all, during the winter. Store the plants in an area
with bright light. They can survive storage in a dark, cool place, but they
will bloom better the next season if they spent the winter with warmth and
light. You'll see the growth will remain straighter and more compact if they
continue to get bright light in the winter. If you have a greenhouse,
keeping the plants at around 70 degrees Fahrenheit is ideal. Alternatively,
you can store them inside by removing the plants from their pots, shaking off
any loose soil and keeping them in a warm attic or closet. If you choose to
remove the leaves, give them a couple of days for the latex to dry before
storage. When the weather warms up in the spring, take them out and trim the
roots before replanting. If you wish, plant them in pots and then submerge
the pots in the ground for easy fall removal. This will also promote good
growth during warm weather. Don't forget to provide some shade from direct
sun for a couple of weeks as they adjust to the outdoors.
Pruning:
You can prune Plumeria at any time using a sharp knife. Be sure to cut at an
angle so the cut won't hold any moisture. The plant will bleed latex sap,
but it will stop in a day or so. If you dip the cut briefly in water, it can
help it stop flowing. If you think the plant is getting too tall, prune it
so the blooms will be at a better height. Your Plumeria will just grow more
branches at the point at which you pruned it and this of course will promote
even more blooms.
Grow Plumeria From Cuttings:
Plumeria
Cuttings for propagation should be at least a foot in length. Allow them to
dry in a ventilated area for up to a week or longer as needed. Basically the
cut needs to scab up or dry. Choose a pot that is 8-10 inches wide and deep.
To plant your cutting make a three inch deep hole in the soil. You can do
this by sticking the cutting into the soil after you have filled the pot and
wet the soil. Take the cutting back out and put some rooting hormone on the
bottom of the cutting. Roots will develop from the bottom of the cutting, so
don't plant it much more than the 3 inches. You may want to pile a few rocks
around the base of the cutting to help prop it up once it is planted. Make
sure it is kept on the dry side (if watered at all). It will take about a
month for your cutting to root (maybe 2 or 3). You will know it has rooted once you have 3
or 4 well formed leaves
(this one needs a few more weeks as leaves are a bit small yet). Here is
what a cutting will look like at around
6
weeks, here it one at
8 weeks (grown
on a heat mat with regular florescent lighting). It is important to provide a warm environment and
bottom heat, it will root better. Just remember that each type of cutting
will have its own growing characteristics and some will emerge quicker than
others. It is best not to attempt rooting until late spring when temps are
at least 65 at night and 75 during the day.
Once planted, if they are kept in moist soil the cuttings may begin to rot.
Cuttings should not be watered until 3-4 leaves have formed (2-3 inches in
size) at the tip
indicating a root system is forming. At that point water sparingly 1 time a
week for the first month. The hotter it is the more you can
water. If it is winter or late fall and you can not provide a heat
mat and strong indoor florescent lighting, it is recommended that you wait to plant
your cutting in late spring. Cuttings can be stored in a cool dry place for
many months. Just wrap them up in some news paper and pull them out when you
are ready to go!
Growing Plumeria from Seeds:
Plumeria can be grown easily from seed, but the seedlings will not remain
true to their variety. All named varieties are grown from cuttings from
plants with excellent characteristics. A cutting will always be just like
the parent. A seedling may have different characteristics from the parent.
If you want to grow your own seed, just let the pods develop and ripen over
several months. The pod will explode sending seeds everywhere, so you may
want to tie a paper bag around it to catch all the seed. Each pod holds
about 100 seeds. Plant the seeds in a 3-4 inch tray with bottom heat. Use a
soil-less mix such as Pro-Mix as the growing medium.
Plant the seeds about ¼ inch deep. Tamp them down firmly and water them
gently. You'll be amazed at how quickly they sprout. Don't overwater. When they have
grown at least two true leaves, transplant them to small pots. They will
grow quickly and will bloom in about 2 to 3 years.
