How Do You Care For Sempervivum Arachnoideum?

Sempervivum Arachnoideum ‘Cobweb Hens and Chicks’ are clump-forming succulents with green rosettes that are coated in a white, hairy webbing.

When exposed to direct sunlight and cold temperatures, the plant becomes purple-brown.

These plants, like other Sempervivums, develop in clusters and spread by offsets and pups.

At first inspection, the plant appears to be coated with spider webs.

My husband asked me if there was something wrong with my Sempervivum Arachnoideum ‘cobweb hens and chicks’ plant when he first discovered it.

Because of their adaptability, they make great ground covers and container plants.

Sempervivum Arachnoideum needs the following to thrive;

Water Requirements

Watering Sempervivum Arachnoideum necessitates dexterity and balance. You must imitate the alpine’s natural habitat.

This implies that you must water the succulents at least once a week. To reduce moisture evaporation, water before dawn or shortly after dusk.

Watering is also advised during these times since the water droplets on the foliage may function as a magnifying glass, attracting heat to the plant and causing sunburn.

After a lengthy period of dryness, Sempervivum Arachnoideum can be revived. You simply need to water the plant more frequently and deeply. Watering succulents twice a week can rejuvenate them and help them grow stronger roots.

Sunlight Requirements

You must grow your Sempervivum Arachnoideum outside if you want it to be happy all the time.

To grow, the succulent requires partial to full sun. Do not confuse the purplish-brown tint with sunburn damage if kept in direct sunlight.

If the leaves of the Sempervivum Arachnoideum are shriveled and dark brownish, this indicates that the succulent has sunburn and should be treated to prevent further damage.

If you wish to avoid sunburn, you must adapt the Sempervivum Arachnoideum to full sun.

Begin by placing the plant in the morning light for 1-2 hours every day.

After approximately a month, expose the plant to the afternoon sun for around three hours every day.

Soil Requirements

Sempervivum Arachnoideum ‘Cobweb Hens and Chicks,’ like other succulent plants, requires well-draining soil.

Proper irrigation goes hand in hand with the suitable type of soil. Succulents are prone to root rot, so well-draining soil is essential for keeping them alive, especially if you’re not sure how to hydrate them.

I’ve been using a basic yet effective combination that has been beneficial to my plants. For improved drainage, I use a cactus potting mix mixed with perlite.

I don’t use precise proportions, but aim for a 2:1 solution of cactus mix and perlite.

Sandalwood can also be used. This is accomplished by combining cactus mix or potting soil with gritty sand. You may also utilize a mix of all three materials.

Fertilization Requirements

When it comes to feeding regimens, these succulents are not too picky. They don’t need to require feedings, but doing so can help them develop.

Assume you’ve decided to feed your Sempervivum Arachnoideum. In that situation, it’s ideal to use a slowly-releasing fertilizer mixture, preferably liquid-based, and apply it once a year to twice a year.

Temperature Requirements

Frost and freezing conditions as low as -15°F or -26°C may be tolerated by Sempervivum Arachnoideum ‘Cobweb Hens and Chicks.’ If you live in USDA hardiness zones 5-8, you may keep the plant outside all year and even put it in the ground.

My plant is kept outside all year and can withstand the heavy rains and frost that we have in Northern California throughout the winter.

Frost protection might help safeguard your plants during harsh winter weather. To help them survive the chilly winter, use frost cloths or small greenhouses.

How Do You Propagate Sempervivum Arachnoideum?

Seeds or root offsets can be used to propagate Cobweb Houseleek.

Locate puppies that appear to be large enough to be removed. When removing the pup, try to get some roots.

You can remove a pup without roots, but you’ll have far better luck with ones that already have roots.

Puppies without roots will ultimately root themselves, but those with established roots have a better chance of survival.

Similarly, larger puppies are stronger than smaller puppies and have a higher chance of surviving on their own.

  • Cut off the offshoot. Some puppies are simpler to get rid of than others. They can sometimes be separated by gently twisting the pup away from the mother plant.
  • It is preferable to remove the entire plant from the container before separating the pup so you can see the roots.
  • Make use of a clean knife. Other times, a sharp object, such as a knife, is required to remove the pup. Separate the baby plant from its mother plant with a clean or sterilized knife, putting the knife blade between the mother plant and the branch.
  • Allow the pup to dry for a day or longer to ensure that any cut or exposed areas are dry, sealed, or calloused. Keep in a cool, dry place away from direct sunlight.
  • Before planting, coat the pup in rooting hormone. Rooting hormones can assist accelerate this process, especially in pups that lack roots.
  • The pup should be planted. Once dried, the pup can be planted on its own. Create a proper well-draining potting mix and plant the pup into the soil. Pack the soil lightly around the plant until secure.
  • Water on sometimes. Puppies require somewhat more moisture than adult plants. Mist the soil lightly with a spray bottle every few days or if it seems dry.
  • Stop misting and water deeply after the plant has become more established and rooted. Watering can be reduced to once a week or less.
  • Keep out of direct sunlight. To avoid sun damage, keep young plants out of direct sunlight when they are first planted in their individual container.

As the plant grows, gradually increases sunshine and sun exposure to meet its demands.

Does Sempervivum Arachnoideum Dies After Flowering?

Light pink blooms arise from the center of the rosettes of Sempervivum Arachnoideum ‘Cobweb Hens and Chicks.’

Sempervivum Arachnoideum ‘Cobweb Hens and Chicks,’ like other Sempervivums, is monocarpic, meaning it dies after flowering.

Monocarpic plants, sometimes known as the bloom of doom, blossom once and then die.

Only the plant that blooms dies; the plants that surround it survive and carry on as long as they do not bloom.

While it sounds terrible, it is not as serious as it appears. The plant normally does not blossom until it has produced a large number of pups and offshoots, ensuring that its death was not in vain.

It might take years for the plant to blossom, and by then, it will have generated enough young plants to ensure the survival of the next generation.

How Do You Water Sempervivum Arachnoideum?

Watering Cobweb Houseleek plants needs some skill. The idea is to replicate their original alpine environment.

In their natural habitat, hardy succulents typically receive 0.5′′ to 1.0′′ of water each week.

Watering early in the morning or late in the evening is suggested to avoid water evaporation or water droplets on the leaves becoming magnifying glasses and burning the plant.

Your Cobweb Houseleek may be resurrected even after lengthy years of drought. Increase your watering frequency and depth, allowing the plant adequate time to respond.

Younger plants can be watered twice a week to help them form roots and grow quicker. During the winter, established succulents do not require additional water from you.

Younger plants, on the other hand, may require a little extra moisture to survive. Dormant plants buried in the snow no longer require as much hydration.

A plant cover is a wonderful choice if you live in a region with chilly, wet winters with little snow.

Is Sempervivum Arachnoideum Toxic?

Pets are not poisoned by Sempervivum Arachnoideum ‘Cobweb Hens and Chicks.’ When first introducing a new plant to house pets, approach with caution.

Green rosettes with white hair and distinctive pink blossoms. The Arachnoideum Sempervivum is ideal for dry, stony areas such as rock gardens, crevice gardens, and trough gardens.

Use it to fill crevices in dry stone walls and plant it in front of garden beds and borders to add a personal touch.

When planted in great numbers, Sempervivum Arachnoideum makes an excellent groundcover.

How Often Do You Repot Sempervivum Arachnoideum?

Sempervivum Arachnoideum succulents should be repotted once every two or three years.

It is best done in the spring or summer, when the plant’s development has slowed. When repotting your succulent, use the proper soil in the new gardening pot.

Fill most of the new container with dirt; approximately a third of the way is ideal.

Next, take the plant from its present pot and gently shake or tap it to let any extra dirt come off; this is also a good opportunity to conduct any necessary trimming before repotting the plant.

Before watering, carefully place the plant in the new pot and cover the root with more dirt. Before watering again, let the soil to completely dry.

Where Can I Plant Sempervivum Arachnoideum?

Cobweb Houseleek is not finicky about where it grows since it may thrive on rock walls, pots, and vertical gardens.

Make sure your Cobweb gets 6 hours of sunshine every day if you want it to grow.

Plant on well-drained, sandy soil and in containers with drainage holes. The soil in which they are grown is critical for these hardy succulents.

The pH of the soil should be between 6 and 8. Sempervivum is typically found growing on mountains with rocky soil and heavy winds, which causes it to dry out quickly.

Succulents have a better chance of developing healthy, big root systems during droughts because they grow deeper to locate water.

Even gardeners with the best intentions might end up with a thin root system and decaying leaves if they keep the soil continually moist for Cobweb Houseleeks.

To maintain the leaves in good condition, use a top dressing. Avoid thick soils or low-lying beds that retain a lot of water.

If you see symptoms of concern, such as mushy, transparent leaves, your plant may be suffering from root rot.

When potting, use alpine-specific compost or make your own by using 1/3 horticultural grit by volume.

We recommend selecting a shallow, broad container in which your Cobweb may expand effortlessly.
