This unique succulent, also known as Peruvian apple cactus or Brachycereus nesioticus, is native to the Galapagos Islands and has become increasingly popular among plant enthusiasts.

What is a Shark Tooth Cactus?

The shark tooth cactus is a columnar cactus that can grow up to 10 feet tall in its natural habitat. However, when grown indoors, it typically stays between 3 to 5 feet tall. It has bright green stems that are covered in small, white spines that resemble teeth, hence its name. The spines grow in clusters which give the cactus a unique appearance.

How to Care for Your Shark Tooth Cactus?

The shark tooth cactus is an incredibly easy plant to care for and is perfect for beginners. Here are some tips to help you take care of your cactus:

Light

Shark tooth cacti need plenty of sunlight to thrive. Place your cactus in a bright, sunny spot, preferably near a south-facing window. If you notice that your cactus is getting too much direct sunlight, move it to a slightly shadier spot.

Water

One of the biggest mistakes people make with cacti is overwatering them. Shark tooth cacti are no exception. They do not require frequent watering and can go weeks without water. When you do water them, be sure to pour water directly into the soil and avoid getting water on the leaves or stem.

Soil

Shark tooth cacti prefer well-draining soil that is specifically designed for cacti and succulents. You can purchase this type of soil at most garden centers or online.

Temperature

Shark tooth cacti prefer warm temperatures and can tolerate temperatures between 60-80°F. Keep them away from drafty areas and cold windows during the winter months.

Fertilizer

Fertilizing your shark tooth cactus is not necessary, but it can help promote growth and keep it healthy. Use a cactus-specific fertilizer and follow the instructions on the label.

Propagating Shark Tooth Cactus

Propagating shark tooth cacti is relatively easy and can be in two ways: stem cuttings and seeds.

Stem cuttings

To propagate your cactus using stem cuttings, simply cut off a piece of stem about 3-4 inches long and let it dry for a few days. Once the cut end has calloused over, plant it in well-draining soil and water sparingly.

Seeds

You can also propagate your cactus using seeds. Sow the seeds in well-draining soil and keep them moist until they germinate. Once the seedlings have grown large enough, transplant them into their own pots.

Common Pests and Diseases

Like any plant, shark tooth cacti are susceptible to pests and diseases. Here are some of the most common issues you may encounter:

Mealybugs

Mealybugs are small, white insects that suck the sap out of plants, causing them to wilt and die. If you notice mealybugs on your cactus, remove them by wiping them off with rubbing alcohol.

Root Rot

Root rot is caused by overwatering and can be deadly to cacti. If you notice that your cactus is ing to turn yellow or mushy, it may be suffering from root rot. Stop watering immediately and let the soil dry out completely before resuming watering.

Scale Insects

Scale insects are small, brown or gray insects that attach themselves to the leaves and stems of plants. They can be difficult to remove but can be taken care of using insecticidal soap.

The shark tooth cactus is a unique and hardy succulent that can add interest to any plant collection. With proper care, it can thrive indoors and requires minimal maintenance. Remember to keep it in a bright, sunny spot, water sparingly, and use well-draining soil. Propagating your cactus is easy and can be using stem cuttings or seeds.
