The Haworthia obtusa plants were only seen in their native areas, but now they are grown worldwide as ornamental succulent plants. They can grow in indoor environments, which makes them suitable indoor ornamental plants.

This not only helps them conserve water for longer but also makes them look like a big rose flower with green thick petals. Its leaves look like green gemstones. They can grow up to 4 inches high from the ground and can have multiple offsets that surround the main plant. This means they can get very wide if these offsets are not separated. These offsets can be used for the propagation of this plant as well. The Haworthia obtusa plant is a flowering plant and produces small flowers during the spring and summer seasons.

Facts

Here are some of the basic facts about Haworthia obtusa

  • The Haworthia obtusa plant is also known as Mini Aloe and a true succulent plant.
  • It has very thick and fleshy leaves. That helps it store water.
  • The Haworthia obtusa plant natively only grows in the Cape Province in Africa.
  • It is considered one of the rarest and most beautiful succulent plants because of its rosette leaf formation.

Requirements to Grow Haworthia obtusa

SoilSandy soil does not trap water and has all the nutrients needed for its growth.
SunIt needs full sun to partial shade, depending upon the season. In winter, it needs full sun, while on hot summer days, it may need some protection from the harmful sunlight.
WaterThe Haworthia obtusa needs a regulated water supply, check the soil before watering. If it is dry, provide it some water, if it is not dry, you should wait a few days. 
Fertilizer Mix fertilizer and water, and feed this to your plant regularly.
Temperature Likes slightly warm temperatures.

Soil Requirements

The Haworthia obtusa plant likes to grow in soil that is well-draining and porous. It thrives if the soil does not trap any water inside. If it traps water, it would harm the roots of this plant. For that reason, it is very important to have soil that is porous and well-draining and does not trap water inside. To get that type of soil, you should mix sand in the potting soil. Apart from sand, you should also mix some pebbles, such as pumice and perlite as well. Make a layer of perlite, and pumice in the pot, after that, put some sand and soil mixture over the top of this layer.

This would help prevent the escape of sand and soil from the pot while draining the water. The Haworthia obtusa plant also likes the soil to have all the nutrients in it for its growth. If it lacks any nutrients, the growth of this plant would be affected. You should put some fertilizers and compost in the soil mixture to make it nutrient-rich. Also, make sure that potting soil is neutral, or slightly acidic. In this type of soil mixture, your plant would not only grow but also thrive.

Sunlight Requirements
