Aeonium Simsii is a much more complex type of Aeonium succulent, meaning it can withstand a wider variety of temperatures, including colder ones that other Aeonium may not handle. This succulent can thrive off temperatures from 74 degrees Fahrenheit down to 65 degrees Fahrenheit; however, it’s common for them to survive in temperatures as low as about 40 degrees Fahrenheit for minimal amounts of time.

Using The Best Soil

Aeonium Simsiis require soil with a higher chance of draining to avoid overwatering. There are a variety of well-draining gardening soils out there that would be safe to use. However, it is highly advisable that owners use a loam potting mix. More specifically, sandy loam for best drainage. If you’re unsure which soil to use or you’re looking for more nutrient-based gardening soils for your succulents, consider speaking to a specialist in the gardening section of any garden store.

Safe Sunlight: Direct Or Indirect?

As mentioned earlier in the article, Aeonium Simsiis are mostly recommended to be raised indoors. But, when they grow enough, you should place them outdoors. However, regardless of where you decide to plant your succulents, the amount of sunlight exposure is a huge component to consider.

Too much direct sunlight is likely to cause damage to the stems of the Aeonium Simsii and the potential burning of the plant’s leaves. To avoid this from occurring, plant your Aeonium Simsii indoors in front of a window where the sun shines throughout the day. Make sure the succulent is receiving bright sunlight but add a sheer curtain to the window for protection.

On the other hand, planting outdoors is still a viable option as long as it is located in a garden with good drainage and is partially hidden from too much sun.

Tip: You could plant the Aeonium Simsii near an enormous tree, near a shaded area where the sun still reaches it a bit, or even in a sheer greenhouse.

Succulents tend to be low-maintenance when providing them with fertilizer – they can flourish without it. However, sometimes, a little nutrition boost from a good fertilizer is positive for your plant. Therefore, if you’re choosing to provide fertilizer, be sure only to use a lower dosage of a natural-based mix.

Avoid Overwatering And Underwatering

To ensure your succulent is receiving enough water, pour until the water starts draining out the bottom of the pot. To establish when to re-water your Aeonium Simsii, put your finger about a third of the way into the soil. Is it moist? Don’t water it. If it’s dry, it’s time for another watering session.

Propagating Aeonium Simsii

Seed Propagation

Plant said roots in a separate gardening pot with the same well-draining soil used for the parent plant. Be sure to keep up on watering this transfer by referring to the watering tips suggested above.

Propagating From Leaves

You need to thoroughly clean some special gardening sheers for this method and carefully remove a leaf from the parent plant. Be sure that you remove the whole leaf and that the leaf is healthy and remains undamaged. Plant the leaf trimming in a gardening pot with well-draining soil. Keep up on watering the soil about once a week unless more is needed.

Propagating From Parent Plant Stems

This method is one of the faster ways of propagating an Aeonium Simsii succulent. They use we’ll-cleansed gardening shears or a sharp knife, carefully incision in one of the parent plants’ healthy stems. It’s recommended to wrap the area in moss and plastic wrap while the new stem forms to avoid diseases. About a few days to a week or so later, you’ll notice a new stem forming. Carefully remove the new stem and plant it in a separate gardening pot with the correct soil. Water accordingly.

Propagation Using Offsets

The most common way of propagating an Aeonium Simsii is using offsets from the parent plant. The offsets are a secondary smaller clone of the parent plant that has grown on the parent plant itself; therefore, you will need to ensure that an offset has grown before this method.

To propagate the Aeonium Simsii, cleanse a sharpened knife or a set of gardening shears. Gently trim the offset off the parent plant, then give it a light shaking or dusting off to remove any excess soil. Another option is to rinse the offset lightly, but make sure you’re gentle with it if you choose to do so. Set the offset in a cool, dry area for a couple of days until it’s completely dehydrated. After those few days, fill the new gardening pot a third of the way up with the appropriate soil and place the offset in the pot. Add any additional soil on top and around the offset, water the plant, and wait for its growth to begin!
