CULTURE REPORT
color patterns: First Blush, with silver
leaves, highlighted by raspberry with
a chocolate center; Painter's Palette,
a mixture reminiscent of a Tartan plaid
of white, red, black and green; Ruby

ruby-colored leaves marked with an
ebony star; St. Nick, a jolly white, red and

green combo that looks like festive
ribbon; Stardust, a rose-pink and silver
combo, studded with thousands of tiny
white dots; and newly added Dancing
Peacock, an exotic, vigorous growing
plant featuring palmate leaves liberally
splashed with silver, rose, lavender,
green and black.
Propagation. Always start with
clean lab stock. TC material is
slightly more expensive than cutting
propagation, but the certainty of
virus-free, Xanthomonas-free plants is
worth it. TC plants also have a faster
finish time and fuller appearance. At
the end of the day, the pennies spent
up front are a good insurance policy
for peace of mind.
Finish Times. From a finished plug,
these varieties will finish a 4-inch pot in
four to six weeks and a gallon in eight
to 10 weeks. It is recommended that
liner not be placed directly into gallon
containers, but rather be transferred to
a 4-inch pot, then a gallon to finish. The
T-REX series can be grown cooler than
typical begonias, but it also takes heat
extremely well, surviving heat trials in
Australia where temperatures reach
well over 100° F; optimal temperatures
are between 55 and 75° F with typical
begonia shade.
Media and Fertilization. A wellThe

drained potting mix consisting of peatlite
mixture works well for these types
of begonias. Fertigate at 150 to 200
ppm of typical bedding plant fertilizer.
Once established, they benefit from a
small amount of slow-release fertilizer.
The EC has a moderate range of 1.2 to
2.4. Watch for salt build-ups. Flush with
clean water should this happen.

accurately dispense your chemicals.
Portable
None required. The T-REX series
branches well from the base and is
compact growing.
Pests and Diseases. Fungus gnats
can be a problem in sodden soils, so
watch watering and let dry slightly to
avoid infestations. Slugs and snails
can mar foliage if not attended to.
Growers usually see very little problem
with mites and aphids. Pythium and
Phytophthora are possible but easily
controlled. Xanthomonas is fatal to all
begonias, so always start with tested
lab stock.
