Sedum lineare care

You know the sedum lineare a little better now. And now we want to focus on care. However, as the succulent that it is, you will already know that these are few and that they do not cause much problem because the truth is that it adapts to everything. In this case, there are some peculiarities to take into account. We explain it to you.

location and temperature

The sedum lineare needs sun. And outside. It’s okay to want to keep it indoors, and you could do it near a window where it gets direct sun for several hours. But the truth is that you will have more problems if you have it there than if you take it out to a balcony, terrace or leave it in the garden.

Generally, you have to provide it with at least 3-4 hours of direct sunlight, and another 5-7 hours of indirect light. In other words, it requires such a large amount of light that it would be almost impossible indoors.

In fact, You will notice that the plant is not doing well if it begins to lose its leaves or grow abnormally long stems. and with much separation of the leaves. If so, it implies that the plant is being etiolated and that can make its appearance ugly.

Now, you can’t buy it and put it out directly in the sun. In the nurseries, all the plants grow under a shade mesh that prevents direct sunlight from coming on them. So if you do, all you’ll do is make him die. You have to acclimatize it.

As for the temperature, you should know that it tolerates heat and cold very well. It is one of the few succulents that will withstand the occasional frost of up to -20ºC. Not many get that stamina.


As a good succulent that it is, the sedum lineare is not demanding with respect to the soil to use. But if We recommend that you make a mixture of universal substrate with earthworm humus and perlite, tree bark or volcanic stone. In this way you will achieve several things: that the plant does not retain a lot of water, that the roots do not run into caked soil and that the plant is oxygenated.


Scarce. This is how we could define it. It is a succulent and, as such, it does not need a lot of water because it accumulates both in the leaves and in the stems.

That’s why, it is best to water it every 10-15 days in spring and summer, and approximately every 30 days in winter.

Of course, it is a plant that has little tolerance for excess humidity, so if there is a lot of it where you live, you will have to control the environment so that it does not rot.

Succulents are not plants that you should prune. But when these grow a lot and can invade the space of others, or you don’t have space to have it so big, it is inevitable to have to cut it down a bit.

What you can do with that is plant new ones or, in case you don’t have room, you could give them away (there are forums where succulents are exchanged) or sell them in second-hand applications.

Plagues and diseases

The sedum lineare is not a plant that is affected much by pests. Although the red spider can make an appearance from time to time and put it at risk.

In any case, it is the diseases that can leave you without a plant. And one of the most important is root rot. When you water too much, or there is a lot of humidity in the environment, the plant weakens. You will notice it because the leaves begin to get wet, as if they had been put in water and they become transparent or dark. Also, when you touch them they are very soft, they even break. Needless to say, they fall off the stem.

If it goes further, the stem itself breaks and you notice that it is black inside. In fact, when you squeeze you will see that it is very white or that it looks like jelly. If that happens, the plant no longer has a solution. That is why it is so important to control irrigation and humidity.


We come to the end, to the propagation of sedum lineare. And in this case you have several options:

Seeds: It is not the most common method, in fact almost no one does it this way because it is quite complicated and also the success rate is low.

Leaves: It is one of the most common ways to reproduce sedum lineare, but it is ineffective and usually slow.

Stem cuttings: This is the one we recommend and the one that will give you the most success. It consists of cutting a stem from the plant and letting it dry for 2-3 days. Then you plant it in a pot and in a matter of a few weeks it will have roots and thrive.

The sedum lineare doesn’t have much of a problem anymore. In fact, like all succulents, they are very resistant and can be ideal in gardens where the climate will be very hot and you cannot have other types of plants. They will thank you growing a lot. Do you dare with her?
