The
Succulent Jade Plant
The
Crassula family has about 300 species of succulent herbs and
shrubs, native mostly to South Africa. The best known and
most loved is Crassula argentea, better known as Jade Plant,
Money Tree, or sometimes Chinese/Japanese Rubber Plant. It
is easy-going. It is beautiful and graceful. It is striking.
It is a great beginner’s plant.
It is also often the victim of being loved to death!
Jade plants need to be treated with benign neglect. A properly
neglected plant can become an heirloom: the one at the Volunteer
Park Conservatory is over 80 years old and going strong!
Here
are some tips on neglecting your Jade properly:
- Light:
it likes bright light with some direct sunlight. If there’s
too little light it won’t flower; also the stems will
become thin and it will drop its leaves.
- Heat:
for an African plant, this guy takes it cool! It’s
perfectly happy at temperatures under 55°F in winter.
It’ll survive temperatures down to 40°F without
complaint.
- Watering:
when it’s actively growing (usually between March
and September), let the soil dry out and remain dry for
several days, then water thoroughly. In the winter, water
even less: several weeks to two months can and should pass
between drinks. (When it’s cooler and there is less
light, plants take much longer to dry out.) Tender overwatering
is Jade’s main cause of death!
- Feeding:
cactus food or houseplant food at one half strength once
a month during active growth.
- Humidity:
Jade plants prefer dry air. Too much humidity, and the growth
will be soft and discolored.
- Repotting:
Again, neglect is good! Jade plants like being pot-bound;
they can live in the same pot for years. Only repot when
absolutely necessary (like, they are ready to burst out)
and then only go up one pot size. Use a good cactus/succulent
mix or make your own: 3 parts potting soil to 1 part coarse
sand or perlite.
- Flowering:
tiny pink or white star-shaped flowers on mature plants
(7-8 years old) during the winter. Jade plants needs lots
of light to bloom.
- Insects:
mealy bugs love Jade plants. They usually develop where
the leaf joins the stem. The safest way to treat is to swab
the mealy bugs with rubbing alcohol on a cotton swab. Some
sprays are effective; make sure the label list Jade Plants,
because Jades are sensitive to a lot of sprays.
So
if you’re looking for a plant to bequeath your grandchildren,
buy a jade and ignore it! Happy indoor gardening!
