What to do with your plumerias if you move
from perfect SoCal plumeria weather
What you tell your relatives when you
send them cuttings
Cold/High latitude growing
CHALLENGES
– Less photons per square inch hitting leaf
– Shorter summers-on avg 180 days of sun
– Temperature swings 50 degree swings several
times in spring and fall
– Low evaporation rates(usually)
– Much colder on average all the time
– Many Freezes/Frosts
– High humidity with colder weather in KC
Surviving Freezes and Frosts
Kansas City has roughly 100 freezes a year not
counting frosts
At least 30 days total under pletely
each year.
Our freezes can last 200 straight hours
Interior Continent-harsher than edges of the
country –record low
-22F, record high 112F
Plumerias out from May to October
Personal History
Rec’d a cutting in 1986 as gift, the person said,
these plants smell really good! it died.
Went to Hawaii in 1994, got dime store cutting.
Got cutting from Hawaii dime store, didn’t know
which way was up. Put it in soil dug out of
yard. Six months later I realized it wasn’t
going to make it
Went to Kansas City garden show, no one there
knew what a plumeria was (!)
THIS IS WHERE MOST PEOPLE QUIT IN
COLD CLIMATES I THINK
Out of frustration, I decide to get another one…
Learned about the PSA from Book Gardening by
Mail, joined the PSA in 1994
Failure failure failure
Rotted easily over 150 cuttings from 1994-1998
Never knew why-no one to ask!
3 years to bloom
Bare-root storage killed many newly rooted
cuttings
Many plants would put up inflos, then they
would drop them right before blooming
Root rots, stem rots
Got better when I built my greenhouse in 1998
Personal History
Did bare-root storage in bas
