GARDENIAS
The beautiful foliage and blooms of gardenias, plus their
wonderful fragrance
makes them almost irresistable to most plant lovers. They can,
however, be a real source of frustration if all the buds fall off as
soon as they are taken home.
There are two reasons this might happen. Buds will drop if moved
to a location of low humidity (from the greenhouse into your
home). Rapid changes in temperature can cause bud drop and
temperatures too low or too high can prevent new bud formation.
Humidity indoors can be increased by the use of a “pebble tray”.
This consists of an oversized pot saucer filled nearly full of pebbles,
and filled with water to about half the depth of the pebbles. The
gardenia pot will rest on top of the pebbles with its roots above the
waterline. The water evaporating around the gardenia will supply
the extra humidity it needs. Careful attention should be paid to
the water level in the tray. It should not dry out, nor should it
be high enough to touch the roots as they will rot if kept constantly
wet.
Bud formation takes place at daytime temperatures of around 70 degree
and nights of around 60 degrees. Plants kept indoors require as
near full sunlight as you can provide.
Outdoors shade during the hottest part of the day is best.
Fertilize with an acid type fertilizer such as Miracid. Despite
its love of humidity do not mist the leaves of this plant as that can
lead to fungus problems.
