Houseleek requires little maintenance

Houseleek requires little maintenance

How high is the water requirement of houseleek?

Houseleeks get by with little liquid for a very long time - the thick leaves serve as excellent water reservoirs, which is why the plant can take care of itself. Only specimens cultivated in planters should be watered from time to time - but carefully, because house lice are extremely sensitive to too much water and especially waterlogging.

Can you fertilize house lice? If so, when and with what?

In principle, fertilization is not necessary for planted houseleek, but you can supply the plants with little (!) Horn shavings (€ 6.39 at Amazon *) or compost while planting. This measure ensures a more intensive leaf color. Specimens cultivated in pots can be supplied with a little blue grain or succulent fertilizer if necessary - but this should rarely be the case.

Do you have to cut house lice?

Regular pruning of the houseleeks is not necessary. You can only remove the faded rosette after flowering has ended, as it will die off anyway.

What should you pay particular attention to when caring for house lice in a pot?

You can put house lice in all sorts of planters, as long as there is always good drainage. Excess water should be able to run off immediately, otherwise the plant threatens to rot or develop root rot. For this purpose, the plant substrate is mixed with plenty of sand or lava rock, and a layer of expanded clay (€ 17.50 at Amazon *) or a similar drainage layer is placed at the bottom of the pot. To prevent the obligatory drainage hole from clogging, you can cover it with a water-permeable fleece.

Should you transplant house lice in the pot?

Regular repotting is not necessary for house lice. On the contrary: like so many other thick-leaf plants, the Sempervives do not particularly appreciate such a measure.

Are house lice infected by diseases or pests?

House lice are very robust. Infestation with fungi or pests is extremely rare. Bad growth, pale leaf color or brittle shoots can usually be traced back to an unsuitable and / or too moist location.

Are houseleek hardy?

As mountain plants, houseleek is absolutely hardy and does not need any additional protection in winter. On the contrary, because the plants need the winter cold for their wellbeing. This also applies to potted specimens that should at most be placed on a styrofoam or wooden base. Only very wet winters can be problematic.


House lice feel good in locations where other plants would not thrive. The plants are used, for example, for planting walls, wall crowns or roofs.
