African spear plant: Diseases and Remedies (3-minute Read)

NOTE: African spear plant may be referred to as Sansevieria cylindrica in this article, in fact, those are the same plants, Sansevieria cylindrica is the botanical name for African spear plant.

The African spear plant (Sansevieria cylindrica), also known as the cylindrical snake plant, is a succulent that consists of upright, gray-green, subtly striped leaves. The leaves are narrow to the point at their tips.

African spear plants can send up a long flower spike from their center that’s full of tiny, delicate, white blooms when they’re grown in optimal conditions. The best time to plant them is at the beginning of the growing season in the spring.

Why does my African spear plant have gray mold spots?

Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.

Our Solution

The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Sansevieria cylindrica.

Why are my African spear plant leaves turning yellow?

Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.

Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:

Each deficiency produces a different yellowing on the Sansevieria cylindrica in question, here’s how to spot them:

  • The first symptom of a magnesium deficiency is yellow patches between leaf veins on elder leaves. The leaf’s core turns yellow while the veins stay green. The edges of the leaf yellow last.
  • Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
  • Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
  • Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
  • A lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.

Our Solution

You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.

Is my African spear plant sunburned?

It is simple to determine whether your African spear plant (your Sansevieria cylindrica) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.

Sunburned

The leaves of your African spear plant can also change color in case it gets too much water or not enough light, as we saw above.

The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.

Why are my African spear plant leaves turning brown?

Most of the time, leaves of a African spear plant that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.

Should I leave my Sansevieria cylindrica in direct sunlight?

No! Don’t leave your Sansevieria cylindrica (or African spear plant) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.

Our Solution

As stated in the paragraph above, the cure is straightforward: simply position your plant’s African spear plant so that it is out of direct sunlight. With proper watering and this method, your plant should quickly come back to life.

Why are my Sansevieria cylindrica leaves drooping or wilting ?

This typically occurs when your Sansevieria cylindrica gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.

Drooping

Whether your Sansevieria cylindrica plant’s pot appears light, the soil and roots are likely fairly dry and need water, so you can readily tell if it needs to be hydrated.

Our Solution

If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the African spear plant right after a dry period thinking that it needs a lot of water.

This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.

Caring Tips for Sansevieria cylindrica

Water Occasionally

Your plant needs water to survive, but it’s crucial to balance the amount and timing of watering. As we previously mentioned, overwatering could be catastrophic for your Sansevieria cylindrica.

You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.

Always keep temperatures stable

It is also a good idea to keep your Sansevieria cylindrica at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Sansevieria cylindrica near a source of hot (or cold) air such as A/C units, radiators or the like.

Keep your African spear plant Dust-Free

This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.

For your African spear plant, this would be a true descent into hell, and it would also appease the pests.

To remove the dust from the leaves of your plant, take a microfiber cloth and gently rub the leaves. You can wet the cloth to make it easier to remove the dust, but never use corrosive products (such as rubbing alcohol!)

Keep drainage in mind

If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.

If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
