How to grow and care for prickly pear cactus at home?

In the United States, one of the most common cactus genera is Opuntia or prickly pear cactus. This plant, which has over 100 varieties, is distinguished by its flat, spiky pads that resemble clubs. Many have prominent, spherical spines, while others have tiny, hair-like barbs that break off when they come into touch with something. Though most people associate cactus with warm-weather desert plants, several kinds of prickly pears can withstand temperatures as high as USDA Zone 4. It is ideal for growing prickly pears outdoors in the spring once the risk of frost has subsided. Though the plant grows slowly, and it might take three or four years for a fresh plant to ripen, prickly pears are treasured for their edible fruits.

How to grow and care for prickly pear cactus at home?

Cut open a fully developed fruit, remove a few seeds, and then rinse the flesh away from the seeds to spread by seed. Allow them to completely dry. Place the seeds in a container of well-draining, damp, but not soggy potting soil. Apply a thin layer of sand or dirt over the seeds. After that, put the pot in a warm, sunny area and cover it with clear plastic wrap. It may take a few weeks or even months for seeds to germinate. After sprouting, seedlings can be placed in containers filled with cactus potting mix.

One of the benefits of cultivating prickly pear cactus is that once established, little upkeep is required. 

Watering

Prickly pear cacti are more troublesome to overwater than to submerge since they are native to warm, dry regions. If there isn’t any rain for a few weeks and you have in-ground plants, give your cacti an inch of water. If not, allow Mother Nature to tend to your gardening needs. 

Water container plants once every two to three weeks or more frequently if the soil dries. In the winter, water once a month on average. This method will vary depending on the containers’ general location and whether inside or outside.

Humidity and temperature

Prickly pear cacti like hot, dry weather since they are accustomed to living in the desert. Don’t worry if the cactus’s fleshy pads shrink or droop in the winter. The cacti’ pads should plump up again when the temperature increases because they undergo cellular modifications to protect themselves from icy conditions.

Prickly pear cacti in containers thrive well indoors if they receive plenty of sunshine and are shielded from breezes and temperature changes.

 

Process of fertilisation

During the spring and summer, when growth is most vigorous, you can fertilise to aid with fruit sets and blossoms. Utilise a product explicitly designed for cactus and adhere to the instructions on the packaging. 

Trimming

Pruning your cactus is only necessary if it begins to spread or becomes too big for its container or area. When pruning, remove complete pads and take out only one-third of the plant at a time. 

Winter maintenance

Using burlap or other heavier materials, you can cover the prickly pear cactus outside on chilly nights in warmer areas. Once the temperature drops, you can move container plants indoors if the weather is predicted to remain below freezing. 

Growing prickly pear cacti from cuttings

Their detachable pads allow for self-spreading, so prickly pear cactus is an excellent choice for cutting propagation. Harvest pads in summer evenings when the temperature is still 60 degrees Fahrenheit or above if you want to cultivate your plants from cuttings.  Cut a couple of pads (at least 6 months old is preferable) and allow the wounds to heal for about a week.

After cutting the pad end off, place it approximately one-third of the way into a container of dry cactus or succulent potting mix and water it well. Before watering it again, set the container in a warm location with indirect sunshine and wait for the cutting to establish root.

 

Benefits of prickly pear cactus

• Opuntia ficus-indica, often known as the prickly pear cactus, is a native of Mexico. In Mexican communities, the fruit and stems of this plant are usually consumed and utilized medicinally.
• As prickly pear cactus reduces stomach absorption, it may decrease blood sugar and cholesterol levels.
• People with diabetes most frequently use prickly pear cactus. Along with many other applications, it is also claimed to treat enlarged prostates, hangovers, excessive cholesterol, and other conditions, although these claims need to be better supported by science.

 

Conflicts and diseases common for prickly pear cactus

The leading cause of root and stem rot in prickly pear cactus is overwatering or excessive humidity, but mealybugs and scale problems can also occur. Furthermore, even in the most hostile environments, prickly pear cactus may get sunburned despite their love of the sun. The plant or its fruits may become scarred and yellow if this occurs.

Like every other species in the Opuntia genus, prickly pear cactus may develop black scabs on their pads due to phyllosticta fungal spores. Remove any diseased pads immediately to prevent spreading the infection to the remainder of the cactus or neighbouring plants, as this cannot be cured.
