Complete Care Guide

As you probably already know, succulents have a notorious reputation for being easy to care for and every tolerant to neglect. Although they are easy-going plants and usually very hardy, there are some important things to remember when caring for them.

Now that you know a little bit about these weird and wonderful succulents, it is now time to dive into how to care for them so that your plants can grow to their full potential. Follow the instructions in this care guide for cobweb houseleek growing success.

Make sure you pot your plant in well-drained soil to avoid suffocating them or exposing them to root rot and other diseases. The soil you choose to plant your succulent in is one of the most important decisions you will make while caring for these plants.

We recommend opting for unfertilized cactus soil rather than pre fertilized potting soil. Not all fertilizers are appropriate for succulents, and unintentionally using the wrong fertilizer for your soil can be detrimental to your plant.

If you purchase your cobweb houseleek from a garden center or online, always repot your plant in a porous soil of your choice. Often, the soil your plant is sold in is not ideal and has been chosen just for show so that the plant is aesthetically pleasing.

If you have done a little bit of research into succulents, you would have noticed that some succulents have a layer of rock on the top of the soil. This is called a soil topper, and as well as being an aesthetic element, it also helps the water drain into the soil quicker.

Adding a soil topper is not recommended for cobweb houseleek plants due to their low-growing nature, as it can interfere with growth and development. As your plant becomes more established, you will not be able to see much of the soil, so be patient and do not be tempted to add a soil topper.


Plant your cobweb houseleek plant in full sun or partial shade, just as long as your plant gets about four to six hours of sunlight every day. Sunlight is vital for any plant, but especially so for succulents, so if you are thinking of placing them in pots around your home, make sure you keep them somewhere that has a lot of natural sunlight, for example, on a windowsill or near your balcony.


Finally, a succulent that is cold hardy, and loves the chilly weather! These succulents can survive in below-freezing temperatures and can even grow in areas that reach -30 degrees celsius.

As well as being very cold hardy, these plants are drought tolerant too, which is great for many reasons. Just remember that these plants hate humidity, so if you live in a humid area such as Florida, you might want to grow these succulents indoors rather than in your garden.


Water your plant as close to the soil as you can. This is to avoid spreading any disease or infection to other parts of the plant. You should also use the ‘soak and dry’ watering method and water the plant only when the soil is completely dry.

Your watering schedule can be thrown out of the window for this succulent. One week you may need to water your plant every couple of days, while during winter months, your plant might not need to be watered at all!

In order to stay on top of your watering chores, keep a plant care journal (you can do this with all of your plants if you like) and tick off and date every time you water, fertilize, and de-bug the plant. This will prevent you from forgetting about your plant.

You can gently touch the soil using your finger to see if it is damp, wet, or completely dry and ready to water. You can use a moisture measuring device too if you want to be really fancy, but it isn’t necessary.


Fortunately, cobweb houseleeks are very low-maintenance plants. Most of the year, there is nothing to do for them maintenance wise other than to add fertilizer during the summer if you feel that your plant is in need of it.

The only time you will need to do a bit of grooming is at the very end of the flowering season. When the season comes to an end, the plants need to be deadheaded. You can do this by carefully removing spent rosettes and blooms that you feel are too mature and interfering with new ones’ growth.
