Prickly Pear Cactus Care.  Optunia is commonly called Prickly Pear Cactus.  It is easy to care for and all cacti require little water and thrive in dry hot conditions.  But we have here some cacti care information to help your cactus garden or xeriscape design look its best.  As most folks know cactuses are low-maintenance plants, but they sometimes develop problems.

Types of Opuntia:

  • Common Cactus
  • Bunny ears
  • Teddy bear Cactus
  • Golden bristle Cactus
  • Velvet Ear
  • Claret Cup Cactus

Type of Soil

They like desert or cactus soil most local Nurseries in the Southwest will have this in stock.  Why cactus soil? Because it does not retain water, unlike regular potting soil. Therefore less water in its root systems. Too much water and Cactus will develop root rot.

When it comes to soil, prickly pear cacti prefer well-draining soil that mimics their natural habitat. A mixture of cactus soil and perlite or sand works best. This combination allows excess water to drain away quickly, preventing waterlogged roots. Additionally, make sure to choose a pot with drainage holes to further aid in proper drainage.

One of the most common mistakes people make when caring for prickly pear cacti is overwatering. These plants are drought-tolerant and only need to be watered once every two to three weeks. When watering, make sure to soak the soil thoroughly and allow it to dry out completely before watering again.

During the winter months, when the plant is dormant, you can reduce watering to once a month. It’s also essential to avoid getting water on the cactus’s pads, as this can lead to rot.


Prickly pear cacti do not require much fertilization, however, a small amount can help promote growth and flowering. Use a balanced fertilizer, such as a 10-10-10, once a month during the growing season. Be sure to dilute the fertilizer to half-strength to avoid burning the plant’s roots. You can also use Cactus Juice to rejuvenate any cactus.  Ask for it at your local Nursery.

Placement of Cactus Plants

Of course, all Cactus love full blazing hot sun.  On the other hand, I have seen Cactus in shade conditions but they will not flower or grow as well unless you have at least six hours of full sun.  Do NOT place cacti near water ponding areas or under roofing water drains.

Problems with Prickly Pear Cactus

Without a doubt, Mealybugs are the biggest problem with this plant.  It is imperative to act quickly when you see evidence of insects or fungi on any plant.  Here are some tips on how to remove Mealybugs from your Cactus plants.

  1. Spray with a strong stream of water to remove Mealybugs.  Be careful not to break off paddles.
  2. Next, use an organic insecticide. Neem oil or insecticidal soap to kill any remaining bugs.
  3. Furthermore, using a systemic insecticide (non-organic) works well.

Root rot is another problem.  Many landscapers install drip water systems to cactus plants, this is not necessary.  Additionally watering by hand or a bucket (if no hose is available) is only required about twice per month the first summer.  After the first year do not water anymore as they will survive on the small amount of rain in the Southwest during the summer seasons.

Conclusion: It is best to observe your plants consistently.  Act ASAP if you see bugs or fungi on any plants.  Organic insecticides do work well however it takes more applications and a longer period of time before you see results.
