Plant my silver jade plant
Typically a mild climate plant, Crassula adapts especially well to the interiors of our homes and apartments. It develops well between temperatures of 18-22°C (slightly cooler in winter, if possible), and it needs light. Be careful nonetheless. Avoid placing the plant directly behind a window with too much sun exposure! It is possible to keep your crassula outdoors if the temperatures in your area don't dip below 0°C. Otherwise, keep it inside!
Water my silver jade plant
Your crassula dislikes humidity, and its water needs are pretty limited — it stores everything it needs inside its thick leaves!
During growth seasons (spring, summer), watering should be regular, about once or twice a month, but controlled, to make sure the roots don't rot. In autumn, gradually reduce watering until winter, when once-monthly watering will suffice.
Spray my silver jade plant
In dry weather, spray your plant with soft water and clean the dust on the leaves: it will be all the more beautiful! Note that this plant tends to grow in the direction of the sun : turn it around it a little, regularly !
Prune my silver jade plant
When some branches do not good look anymore, or are too old, you can prune, ideally in spring, after flowering.
The best way is to cut by hand by breaking the stems gently. Be sure to keep 3 to 5 leaves on each branch, otherwise pruning may weaken it too much.
Fertilize my silver jade plant
Never ! Your crassula likes poor soils, really!
Repot my silver jade plant
At the end of the winter every 3 or 4 years, repot your plant in a pot slightly larger than the current, with a mixture of sand and potting soil.
Propagate my silver jade plant
Your crassula multiplies very easily by cuttings: it survives in fact several days without roots!
Take a twig of 7 to 10 centimeters, but sometimes a simple broken leaf can do the trick!
Let it dry for a few days until a "callus" appears - it's a small bulge - at its base, normally within 4 days.
Then put it in a pot on the surface of a sand substrate or mix slightly damp soil / sand.
Keep it in a room at about 20-25 ° C, and in a location with lots of light, but not in direct sunlight! Water moderately, allowing the surface of the substrate to dry between 2 waterings. After a few days, an identical seedling will appear at the base of the leaf: transplant the seedlings into another pot after about 3 months.
Check on my silver jade plant
Crassula is not very sensitive to diseases, except when it is too watered. It can then be attacked by mealybugs or kermes, mildew or thrips.
Mealybugs are sucking biting insects covered with a sort of waxy or powdery shell. If the leaves become sticky and become covered with sooty mold and the infected parts of the plant dry up, spray rapeseed oil to smother them.
Thrips is a small, 1 to 2 mm pitting insect that appears in hot, dry weather, much like red spiders. A spray of water slightly soaped on the leaves at the first outbreaks may contain it.
In all cases, check the frequency of your watering, and possibly the hygrometry of the room.
Put outside my silver jade plant
Do not hesitate to take out your crassula for the summer! Just avoid placing it directly in direct sunlight or in a situation with too little shelter - acclimatize it slowly, and of course, watch the watering! You should bring it inside at the end of the summer.
Shelter my silver jade plant
Bring back your crassula inside long before the first cool nights, ideally in a room not too heated so that it "feels" it is winter.
It is also on this condition that it will produce small white or pink star-shaped flowers in early spring: a good winter period cool with 5 to 10 ° C at night without artificial light is needed!
You will water once a month in winter.
