The Aeonium urbicum (Saucer Plant) succulent plant is a beautiful addition to any garden or home.
But, before you get an Aeonium urbicum, you must know how to take care of it and propagate the plant so that your succulent can have a long and healthy life in your green space!
In this guide, we will cover everything you need to know about Aeonium urbicum care and propagation.
The Aeonium urbicum succulent plant is a member of the Crassulaceae family and is native to Tenerife.
Aeonium urbicum plants are tall succulents with a single large rosette and an unbranched stem that can grow up to 6.6 feet (2 m) tall. The rosette can grow to be up to 13 inches (32.5 cm) in diameter.
The Aeonium urbicum is usually called the ‘Saucer Plant’ because it has thick, bright green leaves which grow in a flat circular shape that covers a wide area like a saucer.
It has the characteristic that the tips of its leaves tend to turn red when the plant is under stress.
The Aeonium urbicum plant produces hundreds of small, star-shaped, white-to-pink flowers on a 3 foot (90 cm) tall inflorescence during the summer.
How To Care for Aeonium Urbicum (Saucer Plant)
Aeonium urbicum care is very similar to Aeonium care in general.
Below are the main points to take into consideration when caring for an Aeonium urbicum succulent.
Sun Exposure & Light Requirements
Aeonium urbicum plants need full sun to partial shade.
This Aeonium species are sun-loving succulents that need a minimum of six hours a day without shade to thrive and grow well.
A perfect spot for these succulents is a place with morning sun and afternoon shade, preferably outdoors. Still, if not, then a sunny window indoors will do just fine!
Aeonium urbicum plants need a thorough watering once a week approximately.
They are a succulent (they store water in their leaves), so they don’t need as much water.
It is best to allow the soil to dry out completely before giving it a thorough watering.
The Saucer Plant needs to be watered in the morning if you live in an area with a lot of sun during the day.
If you live in an area where it is cloudy all day, they need to be watered at night.
Aeonium urbicum plants do well with a soil mixture of sand, peat moss, and perlite to allow good drainage.
The top layer should be a mix containing between one-third and two-thirds sand or fine gravel.
At the same time, the bottom third is more coarse material such as a cactus potting soil mixed in equal parts with generic garden loam (Top Layer: Sand/gravel; Bottom Layer: Garden loam).
What is essential is a mix of materials that will allow for good drainage.
The soil should be kept moist but not wet and soggy, leading to root rot in this Aeonium variety.
Temperature and Humidity
The Aeonium urbicum likes warm temperatures that usually range from 50 degrees Fahrenheit up to 95 degrees Fahrenheit year-round, with nighttime lows not falling below 60 degrees Fahrenheit or 18 Celsius.
It prefers humidity levels between 40% – 70%. A humidifier can be used if necessary; this should only happen once a day for four hours during dry periods.
If you live somewhere hot enough without needing a humidifier but still want one, then it’s best to use a humidifier that is a cool mist or a vaporizer, not a warm mist.
Here are some tips for managing humidity in the home:
- Use a dehumidifier to remove excess moisture from your home’s air. The device will absorb water molecules found in the air and store them inside a bucket located on top of it until you need to empty it later on.
- Open windows during dry periods can help increase airflow while also pulling dampness indoors due to higher levels of atmospheric pressure when compared with low pressures at night time). This may cause an overgrowth of mold, but this should be mitigated somewhat since fresh outdoor air will be entering the room if you have a ventilator in place.
- Use a humidifier to increase humidity levels in your home and keep a constant flow of fresh air by opening windows, using a dehumidifier, or installing a ventilator that moves hot indoor air outside while bringing cool outdoor air back into the house.
The Aeonium urbicum does not need a lot of extra fertilizer. The occasional use of a diluted liquid fertilizer at about half strength should be enough to keep this succulent healthy and green all year round.
When grown indoors, Aeonium urbicum plants should be fertilized at least once a year during the growing season.
Outdoor Aeonium succulents will generally not need fertilizer. Still, a diluted liquid fertilizer a couple of times a year will replenish any nutrients leached out by the rain.
Potting and Repotting
The Aeonium urbicum plant is best grown outdoors.
This is a hardy plant that will not require a lot of care. However, you may choose to move your succulent into a pot if the weather becomes too dry or hot for it to survive outside.
- The best time to repot an Aeonium urbicum in a container is when it has outgrown its current one and appears healthy and sturdy enough for the project.
- Potted plants should be transplanted during late fall, winter, or early spring. This period provides extended hours of sunlight while avoiding freezing temperatures.
- When transplanting the succulent into a new container, make sure there is at least one inch (about 25 mm) between the bottom edge of the root ball on top of the soil level.
- Don’t disturb the roots, and use a general potting soil that drains well.
- Make sure there is a hole in the bottom of your container big enough for water to drain out freely. Otherwise, it may end up sitting stagnant through winter, which will kill your plant.
- Water thoroughly after transplanting.
Aeonium urbicum only needs a light trimming a couple of times a year.
You will want to trim any dead leaves or flowers as they wither to keep your Aeonium urbicum healthy.
You may need to remove older leaves at times too if they are looking battered by environmental factors such as frost or drought.
These plants grow slowly, so regular removal of old growth is necessary for them not only to survive but thrive.
Pruning Aeonium urbicum is a delicate process because these plants are slow-growing. Any harsh cutting could cause them to stop growing for a while as they recover from the trauma of being cut back too hard.
Pests and Diseases
Aeonium urbicum is a succulent plant that can be susceptible to a few pests.
The most common pests of Aeoniums are mealybugs, aphids, and whiteflies.
These pests usually live in the plant’s leaves, where they feed on sap and excrete a sticky substance that clogs leaf pores.
The best way to get rid of these bugs is by spraying them with a strong spray from a garden hose or other water source.
If Aeonium succulent plants are overwatered, then fungal diseases may also become an issue.
Fungal diseases can be controlled by reducing watering frequency and increasing air circulation around the roots in dry climates.
Excess water and a humid environment should be avoided.
How to Care for Aeonium Urbicum in Winter
The Aeonium urbicum is not a cold-hardy plant and will need a warm winter climate to survive.
The plant is sensitive to frost, breaking its leaves off and causing them not to regrow in the spring.
Aeoniums also cannot withstand a temperature below 15-16 degrees Fahrenheit (- nine Celsius).
When temperatures are that low, water should be withheld from the succulent plants until they reach a more suitable temperature for growth again.
This will help prevent root rot or other fungal diseases from occurring due to too much moisture around roots in dry climates during cold winters when air circulation is poor.
How To Propagate Aeonium Urbicum (Saucer Plant)
The Aeonium urbicum are easy to propagate succulents. They can be propagated by stem cuttings, leaves, or offsets.
Aeonium urbicum can be propagated by a small piece of a stem.
A small Aeonium stem cutting should be taken from a healthy plant, usually a diameter of about half-inch or more.
The cuttings should be allowed to callous for a few days before planting it in a well-draining soil.
The cuttings will produce a new plant very quickly. They can be propagated by more stem cuttings to create a continuous supply of aeoniums for your garden.
This is also an excellent way to propagate an Aeonium that has lost its leaves or been damaged in some other way, such as from frost or insect damage.
Aeonium urbicum plants can be propagated by leaf cuttings.
To propagate the Aeonium urbicum succulent plant, you must carefully remove one leaf from a healthy mother plant.
Allow the cut end of the succulent to callous for about a few days before planting it in well-draining soil.
The leaves are much less sensitive than stem cutting. They need not wait as long after being cut before replanting them into good quality potting mix or garden soil.
They should be watered regularly but sparingly until they have rooted and started to establish themselves again.
Then water more liberally so that there is no chance of drying out while waiting for established roots to provide moisture on their own.
The Aeonium urbicum produces offsets or pups.
A relatively mature Aeonium will produce an offset once a year, with growth rates varying according to climate and temperature.
Offsets should be separated from the mother plant when a pup is 12-14 inches tall.
To separate a pup, carefully remove it with a sharp knife or pruning shears. Take care to keep as many of the roots on the offset intact as possible.
The offset should be planted in a well-drained soil and watered frequently.
The offset will develop a root system on its own, and in a few months, it should be able to support itself.
Is the Aeonium Urbicum Toxic?
The Aeonium urbicum can be toxic to humans and animals.
Always wear gloves while handling this succulent, and do not allow children or pets near aeonium urbicum plants.
The Aeonium urbicum succulent plant is an excellent addition to any garden or home.
The Saucer Plant is an excellent beginner’s plant. They are easy to care for and propagate, so anyone can get one!
