The Christmas Cactus is a popular holiday gift plant. But this
plant is also the subject of frequent debate among gardeners with
regards to care, maintenance and how to get them to rebloom.
While they are indeed a cacti, they are actually tropical plants that
thrive in conditions not usually associated with cactus.
|A Christmas Cactus will do best
in a sunny window away from hot drafts (like heat vents).
Hot drafts cause the buds to drop. Try to find a window in a cooler
room - the
blossoms will hold longer.
Watering is another
tricky subject with Christmas cacti. While in bloom, water the plant
when the top inch of the soil is dry. Stick a finger into the soil up
to the knuckle to test the soil. Don't overwater.
When the blossoms drop, the plant begins a resting period. During this
time, keep the plant on the dry side, but water if the leaves
begin to shrivel.
When new growth resumes, water more frequently.
What about care during the summer?
A Christmas Cactus will thrive outdoors, but
be sure to place the plant in a shady or semi-shady spot. Then water as
needed to keep the plant from shriveling.
The trick to getting the plant to blossom again is long nights (12
hours of darkness) and short days.
Exposing a Christmas Cactus to cool temperatures (50-55°F) will
also encourage blossoming, so leave the plant outside as temperatures
cool in the fall.
Bring the plant indoors gradually when temperatures get too cold, and
keep in a cool, bright window. You will be rewarded with a lovely
burst of flowers in time for the holidays.
