CULTURE REPORT
use of a supplemental chelated
iron or petunia-specific fertilizer
may be used to prevent these issues
from arising.
to maintain proper growth. An
additional cut-back or shear can be
used for growth control too, but it
can take up to three weeks for the
plants to rebloom.
LIGHT
Supplemental lighting is a great
option when growing the Hot+
series. It will not only encourage
early flowering but will also improve
the overall plant performance.
FERTILITY
Fertilize lobelia at a medium rate to
allow for healthy growth; for example,
use 150 to 200 ppm nitrogen of a
20-10-20 option. An EC between
1.0 and 1.3 (using a 1:2 extraction
method) and a pH between 5.6 and
6.4 is recommended. Be sure to
regularly check soil pH and EC as
part of a comprehensive plant health
management program. Also, flushing
with clear water will help to avoid
excessive salt build up in the soil.
BEST USE
The lobelia Hot+ series is
best used in 4-inch pots and
quarts, hanging baskets and
combination planters.

ADDITIONAL NOTES
Although selected for increased
tolerance, lobelia can be sensitive to
high soil pH nutrient deficiencies. The
ESTIMATED FINISH TIMES
Finish times for the Hot+ series
depend on pot size and the number
of plants per pot. All grow times
given are based on the number of
plant plugs from a 102-cell tray
transplanted into the specified pot
size. One plant per pot in a 4.5-inch
pot will take six to eight weeks to
finish; a 6.5-inch pot with two plants
per pot has a grow time of about
seven to nine weeks; and a 10-inch
pot with three to four plants will
take the longest at 10 to 12 weeks
for finishing.
