How to Grow and Care for Houseleeks (Sempervivum) Indoors


Houseleeks, Sempervivum

Sempervivum calcareum

Botanical name: Sempervivum spp
Family: Crassulaceae
Subfamily: Sempervivoideae
Common name: Houseleeks, Liveforever, Hens and Chicks

Description

Houseleeks (Sempervivum) also called Liveforever or Hens and Chicks are popular succulent plants which form mats composed of tufted leaves in rosettes.

Sempervivum are low-growing reaching a height of 4 in. only and each plant grows for several years before flowering. The color of flowers is reddish, yellowish, pinkish or rarely whitish.

After flowering, the Liveforever dies, leaving many offsets it has produced during its life and hence the common name, 'Liveforever'.

These offsets that form around the base of the plants have also given Houseleeks the common name, 'Hens and Chicks'.

They share the name 'Hens and Chicks', with other genera like the similar Echeverias.

The species in the Sempervivum genus are not easy to identify as even one single clone can look very different under various growth conditions or different times of the year.

Sempervivums are very similar and closely linked to each other. Numerous cultivars have been created but a lot of them are not different from each other.

The main interest of these cultivars is not their flowers but the form and color of the rosette-leaves.

Origin

Sempervivum is a genus of about 40 species of flowering plants which are endemic from Morocco to Iran, through the mountains of Iberia, the Alps, Carpathians, Balkan mountains, Turkey, the Armenian mountains, northeastern part of Sahara Desert and the Caucasus.

Houseleeks are completely hardy due to their ability to store water in their thick leaves which allows them to live on sunny rocks and stony places in the mountain, subalpine and alpine belts.

Sempervivum Care Indoors

Houseleeks (Sempervivum) thrives in bright light with some direct sunlight, average warmth and moderately moist, fertile and well-drained soil coupled with fortnightly feeding during the growing season.

Sempervivum requires pruning to keep the plant neat and minimize pest and disease infestation. Repotting is only needed when the plant becomes pot-bound. Keep reading for more on these growing conditions and how to achieve them.

Light Requirements

Houseleeks grow best in bright light with some direct sunlight of at least 4-6 hours. They can also grow under a grow light where natural light is inadequate.

However, avoid exposing the Sempervivum to too hot sunlight before acclimatizing it as it can get sun scorched.

Watering

Water Houseleeks thoroughly during the growing season and allow the top 2-3 in. of soil to dry out between waterings.

Cut down on watering during the cold season and maintain the soil barely moist as growth is minimal at this time.

Avoiding wetting the center of the rosette as it can lead to rotting. Water from the bottom instead.

Use water that is at room temperature to water to avoid plant shock as it can lead to reduced growth.

Ensure that the pot has a drainage hole to prevent the soil from getting soggy as it can lead to rotting. Read more on how to water houseplants.


Temperature

Average warmth between 16-280C during the growing season is ideal for Houseleeks. Ensure that there is good air circulation to prevent fungal diseases.

Fertilizer (Feeding)

Feed Houseleeks every 2 weeks during the growing season with a Cactus and Succulents Fertilizer. Stop feeding during the dormancy stage (cold season) as growth is minimal at this time.

Repotting

Houseleeks have a small root system so frequent repotting is not necessary. Repot at the beginning of the growing season only when it has become crowded in its current pot.

Use a pot 1 size larger than the current one and one that has a drainage hole to prevent the soil from getting soggy as it can lead to rotting. Use a shallow pot and be careful not to bury the stems to prevent rotting.

Soil

The best soil for Houseleeks should be rich in organic matter, loose and free-draining to avoid getting soggy soil. The soil should be loose enough to allow water to drain out fast enough.

Cactus and Succulents soil is ideal as it drains easily. Buy quality Cactus and Succulents Soil for Sempervivum online from Etsy.

Pruning

Pruning Houseleeks is easy. Remove dead and diseased leaves to keep the plant neat and also reduce pests and disease infestations.

Propagation

Houseleeks (Sempervivum) can be propagated at the beginning of the growing season from offsets which form at the base of the plant.

How to propagate Houseleeks from offsets

Carefully seperate the Houseleek offsets from the mother plant. Choose an offset which has several leaves.

Allow the offsets to dry (callus) for 1-3 days before potting to prevent rotting.

Pot each offset in its individual pot in moist free-draining soil and place the set up in a warm, brightly lit place away from direct sunlight.

Water sparingly, only when the soil is dry until the Houseleek is well established and avoid soggy soil as it can lead to rotting.

Sempervivum Problems Indoors

Houseleeks (Sempervivum) problems indoors include loss of leaf color, rotting, yellowing, shrivelled leaves, pests and diseases among others. Keep reading for more on these problems and how to fix them.

Loss of leaf color

Loss of leaf color in Houseleeks is due to too little light as they prefer bright light with some direct sunlight of at least 4-6 hours.

Too little light will cause the leaves to loss their vibrant colors therefore, move the Sempervivum to a brighter spot or instal a grow light where natural light is inadequate..

Rotting base, yellowing and shrivelled leaves

Rotting plant base followed by yellowing and shrivelled leaves in Houseleeks is an indication of basal stem rot disease which is brought about by overwet conditions.

Cut down on watering during the cold season as growth is minimal at this time. Also, ensure that the pot has a drainage hole and the soil is free-draining to prevent the soil from getting soggy.

Diseases

Common diseases in Houseleeks are crown and stem rot disease and leaf spot disease which are brought about by wetting of the center of the rosette.

Avoiding wetting the center of the rosette as it can lead to rotting of the Sempervivum. Water from the bottom instead.

Pests

Common pests in Houseleeks are Mealy Bugs, Scale Insects and Spider Mites. Isolate the affected plant to reduce spread to other houseplants and treat it appropriately for the pests. Read on how to identify and get rid of pests in houseplants.

Are Houseleeks toxic?

Houseleeks (Sempervivum) are non-toxic to humans and pets. Houseleeks are safe to grow indoors.
