About Nopal cactus
Opuntia tehuacana, known as Tehuacán Prickly Pear, is an arborescent or shrubby cactus that can reach several meters in height, notable for its large, flattened, attractive bluish-green pads (cladodes) with yellowish spines. Its vibrant yellow flowers add an ornamental touch in spring, followed by edible fruits. This species is ideal for desert gardens, xeriscaping, or as a specimen plant in hot, sunny climates.
Native range
Mexico (Puebla and Oaxaca)
Care tips
It requires direct sunlight for most of the day for optimal growth and abundant flowering. Watering should be sporadic and deep, allowing the substrate to dry out completely between waterings, especially in winter to prevent root rot. Use a very well-draining substrate, specific for cacti, with a high proportion of sand or gravel. A common mistake is overwatering, which quickly leads to rot at the base and roots.
