Haworthia Arachnoidea, commonly known as Cobweb Aloe, is a spectacular succulent native to South Africa. It is a relatively small succulent that rarely produces an offset.

Haworthia Arachnoidea is famous for having numerous unique foliage in fresh-green, fine spines or thorns on their margins, and mustard yellow tips. They grow to form a protective cover for their rosettes.

Its rosette can grow up to 7 inches tall, and from afar, it looks like a cobweb, into where it gets its common name “Cobweb Aloe.” This succulent produces a beautiful white flower in spring or summer. Like any other Haworthias, Haworthia Arachnoidea is not a monocarpic succulent, so it doesn’t die after it produces a flower.

Haworthia ARACHNOIDEA Care Guide

Caring for your Haworthia Arachnoidea is a must to do as the owner. Here is a simple guide to help you in your succulent journey.

Watering Technique

Watering Technique

Haworthia Arachnoidea requires minimal watering like any other succulents. Making sure that your plant does not sit with moist soil for a long time is a must.

Moist soil tends to cause root rot which is the leading cause of death for succulents. Water Haworthia Arachnoidea once every two or three weeks or wait for the soil mix to completely dries out before watering again. 

Tips: * Use a water bottle instead of a spray bottle when watering your Haworthia Arachnoidea. By doing this, you help your plant avoid possible leaf rot.

* Collect rainwater, then use that in watering your plant. Rainwater has the right amount of minerals that Haworthia Arachnoidea needs.

* Avoid using cold water or ice cube in watering the Haworthia Arachnoidea. Coldwater tends to cause shock to the succulent, especially to its roots.

Light Condition for Haworthia Arachnoidea

Lighting Condition

Light is one of the essential things that help Haworthia Arachnoidea live. Without light (sunlight or grow light), the succulent will have pale-looking leaves, making it challenging to thrive. That is why knowing how much sun exposure or light does Haworthia Arachnoidea requires is necessary.

Indoor – If the Haworthia Arachnoidea is used as an indoor houseplant, it must be placed near a window where sunlight can get through. It is better if it gets morning light. 

Outdoor – Placing Haworthia Arachnoidea outdoors is not a problem. It can thrive in partial shade and must be away from direct sun exposure. Too much sun exposure might harm the succulent leaves and may cause sunburn.

Does Haworthia Arachnoidea need repotting?

Repotting

Repotting Haworthia Arachnoidea can be done once a year or two. Repotting is truly helpful for your plant. Aside from giving it fresh and fertile soil, you also ensure your plant’s safety from possible bacterial infection.

In doing this, you need to carefully remove the Haworthia Arachnoidea from its previous pot, remove the remaining soil on its roots, and cut that off if there is any part of the rotting root. Let the roots form callous for three days, then prepare a pot with soil mix. And you can plant your succulents afterward. 

Soil

Soil Mix

The best soil for Haworthia Arachnoidea must be breathable, non-compacting, and of course, well-draining. Many soil mixes are available everywhere, and you can always buy one.

But aside from that, you can also make your own if you want to ensure that the right amount of ingredients is present in the soil mix. Because some soil mixes have turface on them, which is not necessary for the Haworthia Arachnoidea as it helps retains water rather than drains it. So, if you are thinking of making your own, you can refer to the chart below.

  • Three parts all-purpose potting soil mix
  • Two parts coarse sand (avoid using turface because it is made up of clay and helps water retention)
  • 1 part perlite or pumice
  • A small amount of coconut coir

Take note: You can constantly adjust the number of ingredients. If you want it more porous, you can add more coarse sand.

Hardiness and Temperature

Temperature

Haworthia Arachnoidea belongs to the soft variant of succulent, which means it is not cold hardy and prefers warm temperature.

It also loves a less humid place with good air circulation. This plant can tolerate light frost but not too much cold.

In winter, it is best to transfer Haworthia Arachnoidea indoors to avoid root rot problems.

Is fertilizer required? Fertilizing your succulents in their growing season will help the plant. But use only a dilute and weak fertilizer. Avoid feeding the succulent during its dormancy as the plant is at rest during that time.

Pruning

Pruning

Pruning will help Haworthia Arachnoidea to be healthy. Doing this also helps avoid infection from an infected leaf to another.

Brown dots on the leaves and broken foliage are symptoms of pest infection mainly caused by aphids or mealybugs. 

If this happens, remove the affected leaf and spray a weak insecticide or isopropyl alcohol to the plant to move away from the pests hiding in your plant.

Pots

Pots

Gardeners love to choose beautiful and eye-catching pots for their succulents. And you can also do the same.

They are available almost everywhere. You can choose from varieties of choices such as ceramic pots, plastic pots, terra cotta pots, wood pots, metal pots, and even cast-stone pots.

But it is always necessary to remember that each container has its specific function, depending on what plant you will put inside it. As for that, you need to know these essential factors:

Materials – The best pot to use for Haworthia Arachnoidea is the ones that don’t absorb heat and cold easily. That pot must be able to withstand extreme temperatures. 

Drainage – Having good drainage is one of the essential factors to consider. Without this, there is a significant tendency that Haworthia Arachnoidea will not survive. So, in choosing the right pot, it must provide excellent drainage.

Pot Size ­– Choosing the proper pot size is also necessary. If the succulent is small, it needs a small pot. If it is a mid-sized plant, it must be in a mid-sized container. The roots need space to stretch out for the plant to grow. So, if the pot size does not match the succulent, there will be a problem.

Can Haworthia Arachnoidea be arranged with other succulents?

Yes, making a succulent arrangement is also possible. There are just a few reminders that you need to know.

First, Haworthia Arachnoidea must be grouped with succulents that are not cold-hardy. Lastly, if the Haworthia Arachnoidea is still tiny or an offset, put it in front of the arrangement, and if it is a grown one, put it in the middle or at the back.

This is to make sure that the succulents do not overlap one another. 

Diseases and Causes

Disease and Causes

There are some diseases that Haworthia Arachnoidea can have. They are root or leaf rot, wrinkling and dry leaves, and sunburned leaves. 

1. Problem: Root or leaf rot 

Cause: Overwatering

How to solve: In solving this issue, you need to repot your Haworthia Arachnoidea. Carefully remove the succulent using a shovel. Cut off the affected areas of the roots and remove the soil that clings into them. Airdry the roots for three days, plant them in fresh and fertile soil, and a well-draining pot. Adjust your watering schedule, and only water the plant once every two to three weeks, depending on how fast the soil dries, and once every month in winter.

2. Problem: Wrinkling and dry leaves

Cause: Underwatering

How to solve: There is no need to replant an underwatered Haworthia Arachnoidea, but you need to adjust your watering schedule. Do not water the plant a lot to cope up with the days it wasn’t drenched. You need to follow the proper watering schedule (once every two or three weeks), or you can use the “soak and dry method.” 

3. Problem: Sunburned leaves

Cause: Too much sun exposure in direct sunlight

How to solve: Carefully remove the affected leaf using a clean knife or scissors. Make sure to remove every part of that affected leaf.

Is Haworthia Arachnoidea toxic to humans and pets?

Toxicity

No, Haworthia Arachnoidea is non-toxic to humans and pets but is not an edible plant, so do not eat it. Doing so may lead to stomachache, vomiting, and diarrhea.

How to help Haworthia Arachnoidea survive in winter? 

Transferring your Haworthia Arachnoidea inside during the winter season is a great idea. It can not tolerate extreme frost, so it is likely to die when left outside. Use a grow light as a substitute for sunlight.

This will help the succulent to survive in that crucial time. Do not forget to rotate the plant once in a while to ensure that each side gets enough light. You can also use a plant cover to keep away pests from coming into the Haworthia Arachnoidea.

Haworthia Arachnoidea Propagation

Propagation

Propagating Haworthia Arachnoidea can be done in three easy ways.

Through leaf cuttings

Cut some matured leaves from a grown Haworthia Arachnoidea using a clean knife or scissor.

Airdry the cuttings for three days until they form callous. It is necessary to do this to avoid infection.

Next, prepare a shallow planting container, then lay the leaves there until they grow roots. When that happens, transfer the cuttings to their pots.

Propagating Haworthia Arachnoidea through offsets

Remove the pup from its mother and airdry the roots for three days or more.

Then prepare a well-draining pot with soil mix. Plant the baby plant to its new home. 

Propagating Haworthia Arachnoidea through seeds

In a shallow planting container, carefully spread out the Haworthia Arachnoidea’s seeds, ensuring enough space among them. And do not cover them with soil. Wait for few weeks until they grow roots before planting them separately.

This cobweb-looking succulent is indeed a head-turner. It is an excellent addition to your succulent collection, or you can use it as a house decoration.

And if you are looking for a low-maintenance yet beautiful plant, Haworthia Arachnoidea is the answer. May this article help your succulent heart. Happy planting!
