CULTURE REPORT
Lobelia
Hot+ Series
This next generation
of heat-tolerant
lobelia offers larger
flowers and more
uniform plant habits.
BY BART HAYES
T
he Hot+ series of lobelias are
an improved version of the
classic series that redefined
lobelia. This exceptionally heavybranched,
mostly mounding series
takes all of the best attributes of the
original Hot series of lobelias -
like incredible heat tolerance and
heavy flowering - and makes the
flowers larger and brighter. They are
ideal for 4-inch pots, with inclusion
in combination and hanging basket
programs giving amazing results as
well. The season-long flowering and
uniform habit make it easy to produce
for growers and give home gardeners
better performance.
STICKING
Hot+ cuttings can be stuck into
a 105-count tray filled with welldraining,
loose-filled propagation
media or an engineered soil plug for
best results. They hold up best at a

steady temperature of 68 to 76° F. It's
important to mist only enough to keep
the soil moist and humidity high until
root initials are visible.
ROOTING HORMONE
Using KIBA rooting hormone at
100 ppm is recommended to enhance
the rooting speed and uniformity
of lobelia.
CULTURE NOTES
A light pinch is recommended once
the plants have rooted to the side of
the propagation cell and have started
to produce new growth, which
usually occurs 17 to 20 days after
sticking. This will enhance branching
and help control the growth habit of
the Hot+ series.
GROWING
Lobelia plants can be transplanted
once they are very well rooted into a
well-balanced, well-drained soilless
media. Keep a steady temperature
range of 68 to 72° F for the soil
throughout the rooting period, then
gradually reduce the temperature
to around 62 to 66° F for finishing.
Cooler temperatures can be used for
additional height control, if needed,
but keep in mind it will likely take
additional time to finish.
After the lobelia are initially
established, continue to water plants
early in the day to allow foliage to dry
and allow the soil to dry slightly in
between watering for best results.
GROWTH REGULATION
Good water management and cooler
growing conditions - 58 to 62° F -
will help restrict excessive growth
and result in overall better quality. If
more control is needed for your lobelia
production, B-Nine (daminozide) at
1,500 to 2,500 ppm can be used
