Is Cactus A Vegetable Or A Fruit?

Yes, cactus can be considered a fruit in botanical terms because it develops from the flower and contains seeds, which is the definition of a fruit.

In general, any plant part containing seeds is classified as a fruit, regardless of taste or culinary use.

This applies to cactus fruits, which are typically sweet and have a juicy texture, but also to other fruits commonly used as vegetables in cooking, such as tomatoes, eggplants, and peppers.

Is Cactus Edible?

Cacti are not only unique and beautiful plants, but they are also edible. However, knowing which types of cacti are safe to eat is important.

Generally, all fruits of true cacti are safe for consumption, but the same cannot be said for cactus leaves or other parts. Below are five types of edible cacti:

  1. Bunny Ear Cactus: The pads of the bunny ear cactus are a popular ingredient in Mexican cuisine. The pads are typically cooked in stews, soups, and salads. They are a good source of fiber, vitamins, and minerals.
  2. Prickly Pear Cactus: Prickly pear cactus is a popular ingredient in Mexican, Central American, and South American cuisine. The fruit of the prickly pear cactus is sweet and juicy and can be eaten raw or cooked. It’s often used in salads, drinks, and jams. The pads of the prickly pear cactus are also edible and can be cooked like other cactus pads.
  3. Dragon Fruit Cactus: Dragon fruit cactus, also known as pitaya, is a tropical fruit popular in Asia and South America. The sweet and juicy fruit can be eaten raw or used in smoothies and desserts.
  4. Elephant Bush Cactus: The leaves of the elephant bush cactus, also known as Portulacaria afra, are edible and have a sour and tangy flavor. They are commonly used in salads or as garnish.
  5. Nopal Cactus: Nopal cactus, also known as prickly pear cactus, is a staple in Mexican cuisine. The pads are sliced, cooked, and used in dishes like tacos, omelets, and soups. They are a good source of fiber, vitamins, and minerals.
  6. Saguaro Cactus: The edible saguaro cactus is native to the Sonoran Desert in Arizona and Mexico. While it’s not typically eaten, its fruit is edible and has a sweet and juicy flavor. The fruit can be eaten raw or used in jams and jellies.

Examples of non-edible cacti

While some cacti are safe to eat and have nutritional benefits, toxic poisonous cacti should be avoided, including cactus flowers. Here are five examples of non-edible cacti:

  1. Peyote: Peyote cactus contains mescaline, a hallucinogenic substance that can cause severe health effects. It’s often used for spiritual and medicinal purposes, but it’s illegal to consume without a license in most countries.
  2. San Pedro: San Pedro cactus is also known for its hallucinogenic properties and contains mescaline. It’s used for traditional and religious ceremonies in South America but is illegal in most countries.
  3. Cholla: The cholla cactus’s spines and glochids (hair-like structures) are highly irritating and can cause pain, itching, and swelling. They can also detach from the cactus and get embedded in skin, clothing, or animals.
  4. Barrel: The barrel cactus contains oxalic acid, a toxic substance that can cause severe digestive upset, seizures, and even death in humans and animals.
  5. Peruvian Torch: Like peyote and the San Pedro cactus, the peruvian torch cactus also contains mescaline and is used for its hallucinogenic properties. However, it’s illegal in most countries and can cause severe health effects if consumed in large quantities.

How to Grow Cactus

How to Grow Cactus

Cacti are plants that are adapted to grow in arid and dry climates. They are found in various habitats, including deserts, grasslands, and forests.

Some popular types of cacti include prickly pear, barrel, saguaro, and dragon fruit.

Here are 5 steps to successfully grow a cactus:

Step 1: Choose a container with drainable soil

When selecting a container for your cactus, choose one with drainage holes to prevent water from building up at the bottom.

Fill the container with soil that is specifically designed for cacti and succulents. This soil is usually sandy and has excellent drainage properties.

Step 2: Dig holes in the soil according to the cactus root ball’s depth and its stem width.

Make sure to plant the cactus at the same depth as in its original pot. This will help it establish roots and grow properly.

Dig holes in the soil that are deep and wide enough to accommodate the root ball of the cactus.

Step 3: Put the cactus in the hole. Fill the gap around the root ball with the soil.

Gently remove the cactus from its original pot and place it in the hole you’ve created in the new pot.

Fill the gap around the root ball with the soil, making sure to pack it down firmly.

Step 4: Water the cactus moderately

Water the cactus moderately, being careful not to overwater it. Let the soil dry out completely before watering again.

Cacti are adapted to survive in dry conditions, so too much water can cause the roots to rot.

Step 5: Place the pot to give the cactus the right amount of sunlight

Different types of cacti require different amounts of sunlight. For example, prickly pears and dragon fruit require 6-8 hours of direct sunlight, while elephant bush only requires indirect sunlight.

Place the pot where the cactus will receive the right amount of sunlight for its specific needs.

Step 6: Monitor the cactus plant

Once you’ve planted your cactus, watch for any signs of distress. Look for drooping or yellowing leaves, as these are signs of overwatering.

If you notice any signs of distress, adjust your watering and lightning schedule accordingly.
