Jade, Crassula argentea, is a succulent. It does bloom under
just the right circumstances, similar to Christmas cactus, but
mine have never bloomed in four years. Many times when
they are grown as houseplants they don't bloom, or at least
not until they are very old. In their native environment jade
plants can grow up to 10 foot tall!
Jade plants are slightly finicky, but given the
conditions they need, they are a good houseplant
that will last for years and years. You can
water too little, or too much and the plant isn't
very happy. The soil should not become bone dry,
but yet you don't want it to be moist either. I
water a little more in the winter since it's so
dry in the house. Light can be bright to
average, but in the summer you may want to avoid
the hot direct sun. A sunny southern window is great
in the winter. If you notice brown edges on any
of the leaves then it may be getting too much
direct sun. If the leaves look a little "withered",
it's not getting enough water. If you notice new
leaves forming then it's going through a growth
spurt and you can water more freely for a time.
The potting soil should be average with a little
sand added. Start out with a small, inexpensive
Jade plant to try it out; they grow at a nice pace,
as most succulents do if given enough light and
the right conditions.
Most of the emails I receive ask about various problems with
the plant. Jade needs temperatures above 55 degrees, and it
should be fairly consistent--not up and down. You also don't
want to provide too much humidity, so don't leave water in the
bottom of the tray if you are using one or keep it in a humid
room. There are quite a few things that can happen to a jade
plant such as scale, pythium rot, and certain kinds of mold. If
you notice any white spots or bumps, try placing the plant in
the tub or kitchen sink and spraying it off with a hand sprayer
or handheld shower head. Make sure you get the underside of
the leaves and the stems too. If this doesn't seem to make a
difference, you can also clean the leaves with a cotton ball
that has been soaked in rubbing alcohol.
Rot can be by overwatering or watering from overhead rather
than from the side, or too much humidity or temperatures. The
jade is not a cactus, but it needs even less watering than an
African Violet, and a similar type of soil. Be sure to water it
before it completely dries out, but don't keep the soil moist.
Try to establish a pattern to your watering--once a month is
generally a guideline. Put your jade plant on a schedule and
keep it whenever possible. You can fertilize lightly during
the warm months, but withhold it around October through
February, when it's somewhat dorment.
Another thing that is important is to always remove dead leaves
or stems from the plant and pot. Keep the jade neat. They will
tend to get dusty, especially in old homes such as mine. Wash
them gently with water, but don't use any type of plant cleaner
on the leaves or oils. You can trim your jade plant or "pinch"
it to encourage branching. The removed stems or leaves can
be left out for the ends to dry for a day or two, then place the
ends in a pot with commercial potting soil that you've mixed in
a little sand. Plant the cutting an inch or two deep and give it
VERY little water until it roots.
Most people want to know why their jade is losing it's leaves.
Unfortunately there isn't just one answer. Overwatering or
underwatering can cause leaf loss. Also, too much sun or
not enough can cause this too. The best thing to do is try to
provide the best care based on what I've mentioned and
if all else fails, take a cutting and start over.
QUESTIONS & ANSWERS
I have a Crassula argentea and I live in Florida in the forest
and I was wondering if I could plant my Jade in the ground and
where should I plant it? In the sun or the shade? ~Vickie
The jade plant needs a warm climate in winter, and it also needs
some protection from very hot direct sun. The leaves can scorch
and then it needs to be moved to a cooler place. It can only
survive outside in temperatures above 20 degrees or so. This
would usually include Zones 9, 10, 11 and 12. Also avoid a wet
soil or the roots could rot. A partial shade in a dryer soil should
be good for it. If your forest location isn't soggy and has some
sun it should work fine for the jade.
I took a clipping off of a friends jade plant, and I'm wondering
if it will grow. I put it in a cup of water to try and make the roots
come out, but I'm wondering if that is what I should have done
and how long the roots will take to sprout if I did it right.
My jade plant has grown so much that the stems can't support
the weight. I have tried staking it up but the weight still makes it
droop. Should I cut it back severely, I tried repotting it into a
larger pot but that didn't help. ~Thanks, Marian
Let's start with the rooting of a jade plant. Use a very sharp
sterile knife and cut the piece off. Make sure it's healthy
with no signs of rot or disease. If you have it, dust it with a
rooting hormone. Leave the cutting in a warm, dry place
until what looks like a callous forms over the cut. This usually
takes 1-2 weeks, and at this point you can plant the cutting
into sterile potting soil. VERY lightly water it just to dampen
the soil. Gradually add a little more water each week as the
root develops. Keep the pot at 70-75 degrees F. Do not use
fertilizer during the process till the plant is established.
As far as the jade plant falling over, this usually means it's not
being watered deep enough. I've had this happen. First I took
a thick piece of wood-- I used a piece of trim I had laying in
the basement. It's about an inch thick, and I put it in the soil
carefully so I would injure any of the roots and I leaned the
plant on it. Every plant is different, but if you get the right spot
it will work. I didn't have to tie it, but you can. Next don't water
MORE often, but water the pot deeper. If you do this, your
stems will become stronger and will stand on their own.
READER'S TIP:
Rooting techniques for jade plants....firstly jade is slow growing
so patience is required. I had found it difficult to root from a
stemmed cutting because the roots that grow are so small that
it is difficult to support such a "large" plant. When we visited
the Franklin Park Conservatory in Columbus Ohio, there were
jade leaves lying on potting medium, so I thought I'd give that a
try....Amazing! Since spring I have a small jade that is about
four inches tall with another beginning to grow from that sprout
as well, and the roots seem very able to support the plant since
they have grown together. ~Carol
