Identify my cotyledon
Cotyledon orbiculata, the pig's ear, is a shrubby plant with thick, persistent and fleshy leaves that grow in opposite pairs.
The thick leaves store water and are covered with a cuticle to limit the evaporation of water by the leaves, which allows you to space waterings widely.
It develops from a basal rosette, from which emerges a bulging stem. It can reach one meter in height, in its panicle inflorescence. The flowers have a tube shape, weeping.
Plant my cotyledon
A plant of rather warm climate, the pig's ear will adapt rather well inside our houses and our apartments.
It will grow well with a temperature of 18-22 ° (less in winter, if possible) and needs a lot of dim light.
Avoid placing it directly behind a glass too exposed! Plant preferably in a mixture of special soil for succulent, i.e. sandy and lightened with some gravel.
Plan a pot heavy enough because otherwise your plant may tip over.
Water my cotyledon
Your cotyledon fears 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 cotyledon
In dry weather, spray your plant with water not too hard 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 cotyledon
When some branches do not have a good appearance or are too old, you can prune, ideally in spring, after flowering.
The best is to cut by hand by breaking the stems gently. Be sure to keep 3 to 5 leaves on each branch, as this may weaken it too much.
Fertilize my cotyledon
From time to time.
Repot my cotyledon
At the end of the winter every 3 or 4 years, repot in a pot slightly larger than the current, with a mixture of sand and potting soil.
Propagate my cotyledon
Your pig's ear is multiplied 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 cotyledon
Watch for aphids. Well, actually, even if you see some it is not very serious, cleaning the leaves from time to time will slow them down.
Put outside my cotyledon
Do not hesitate to bring out your pig's ear for the summer! Just avoid placing it directly in direct sunlight or in a poorly sheltered situation - acclimatize it gently, and of course, watch the watering! You should put it back inside at the end of the summer.
Shelter my cotyledon
Bring it inside well before the first cool nights, in a room not too heated so that it "feels" that it is winter: 5 to 10 ° C at night without artificial light!
You should stop all watering until spring.
