Sedum Sieboldii, also known as Japanese Silk, is a species native to cold and temperate areas that stand out for its creeping or hanging bearing, developing depending on its place. This plant’s beauty lies in the leaves’ shape and arrangement; these grow hugging the long and thin stems and giving it a peculiar and exotic air, whether it is left on the ground or decided to put as a hanging plant. The characteristic of their stems is the fact that they can reach up to 10 inches long.

The Sedum Sieboldii is a perennial plant that, despite losing its foliage and even branches during the late autumn and winter, when spring comes, regains all its splendor, which lasts approximately until the beginning of autumn. Each time this cycle is fulfilled, the shoots of our Japanese Silk will be stronger and stronger. Its blue-gray leaves will increase slightly in size. Its jagged edges will reach an attractive reddish color; it will also develop a fall bloom of beautiful, abundant pink star-shaped bouquets.


Other than being super easy to care for, these Sedum Sieboldii succulents have another good thing: they can (and have) been used in many different ways! For instance, Sedum Sieboldii and some other Sedum Genus varieties were used as a medicinal property for multiple types of skin diseases and cases of epilepsy. Another exciting thing this succulent feature has been used for is cooking – the leaves of this succulent have( and still can at times) been eaten after being sautéed. In contrast, another Genus of this species was used for making condiments.

Sedum Sieboldii Care

As Sedum Sieboldii belongs to dry climates, the roots are adapted to the consequent soil conditions. For this reason, if it is grown in a pot, we must make sure that the soil is adequate for our Japanese Silk to grow healthy; a mineral substrate with good drainage such as the pumice can be ideal. It is vital that the pot where we plant it has holes in the base to allow good water drainage, and, if we use a plate or tray at its bottom, make sure to dispose of all excess water frequently.

If we want to plant it outdoors, it can grow in all soil types; Although it is advisable to use a little pumice in the hole where it will be produced. We must consider that this must be soil with good drainage since an accumulation of water could have adverse effects on our Sedum Sieboldii.

Silks from Japan, having succulent characteristics, do best in hot climates and require semi-direct exposure to sunlight to show their full appeal. Being outdoors should be placed in a bright area where it can receive Sun, but its leaves can burn gradually if it gets too much direct and constant sunlight. To keep it inside the house, it needs to be where it indirectly receives enough sunlight through windows.

It can also grow and develop in less warm and illuminated areas, but in these cases, it is imperative that the plant’s soil is not always damp, or it will begin to rot. We must be careful of how much light we provide it since if we exceed it, it can burn, but, if it is not enough, it may begin to develop etiolation that causes its leaves to start to separate in search of sunlight and lose their aesthetic.


Sedum Sieboldii succulents are not too picky with temperatures due to their ability to withstand colder temperatures. This is because the succulent is one of the hardier species. More specifically, Sedum Sieboldii plants can handle any temperature from 40 degrees Fahrenheit to 70 degrees Fahrenheit; however, they will be fine at temperatures lower than that for a certain amount of time.

Watering of Sedum Sieboldii

The watering of this plant should not be ample, considering that they are resistant to drought. During the spring and summer seasons, it will be necessary to keep our Sedum Sieboldii hydrated; however, the waterings should be spaced apart, leaving even a day after the substrate is completely dry before watering it again. In winter, we must reduce watering a lot, being that in summer, at a high temperature, we must water it approximately twice a week; as the climate cools, we must gradually reduce this frequency.

When winter comes, it will only be necessary to water it once every three weeks or even a month, depending on the humidity. Even if the humidity outside is very high or it rains continuously, we recommend that we carry our Japanese Silk inside to prevent it from developing rotten roots. On the other hand, we cannot be stingy with watering because its leaves will begin to wrinkle and fall off if it becomes dehydrated.

Fertilization of Sedum sieboldii

The fertilizing period for this species begins in the spring, extending into the summer. We can use a fertilizer for cactus without problems, but, thanks to the fact that there are different types, we will use the most suitable one depending on how we cultivate or grow our Sedo from Japan. If we grow it in a pot inside our home, the most advisable thing is to use a liquid fertilizer; we must dilute the dose in water and water it with it. Powdered compost is also a good option thanks to its rapid effectiveness, but this is not advisable for potted plants as it can affect the drainage of the soil; it is best to use this type of compost on plants that are directly in the ground.

Using fine compost can be a bit of a chore, this is good for Sedos both indoors and outdoors, they are quick to dilute and quite useful, but they have a very high risk of overdose. If this happens, it will burn the roots of our plant. Finally, we have stick fertilizers. These are quite curious. Watering Sedum Sieboldii makes them stick in the loose and are diluted. They are an excellent option since they work well both in potted plants and on direct soils.

Pests Or Diseases

Sedum Sieboldii attracts pests such as slugs, weevils, and snails when they’re left to grow outdoors, while pests like mealybugs, scales, and aphids are more commonly found on these succulents when they’re indoors. Other than that, Sedum Sieboldii can also experience fungi, bacteria, and root rot, which can all form due to overwatering the succulent. Remember that any of these issues left untreated can lead to further, more severe, stubborn problems.

After about a week, these cuttings will begin to develop their roots and flower healthily.

Propagation By Seeds

Sedum Sieboldii can be propagated in multiple ways, with seed propagation being one of the most common techniques. Propagating this succulent with seeds is much easier than it may sound; however, it does take a bit longer than the other techniques available.

Spring is also an excellent time to transplant our Sedum Sieboldii. This process should be done when observing that the roots start to emerge through the pots’ drainage holes. Japan silks are easy plants to grow and can be resistant to many pests and diseases. When we must take care of them, the most is in the rainy seasons, both because of the cochineal, slugs, and snails that usually feed on their leaves and stem.
