Pereskiopsis spathulata GRAFTING CACTUS (plant)

Pereskiopsis, also known as Leafy Cactus or Grafting Cactus, is a genus of the Cactaceae family with an unusual, very fast-growing form that resembles a small shrub. It features large green leaves and small thorns beneath them. It is native to Mexico and Guatemala. In its countries of origin, it easily reaches 1 to 2 meters in height.

The foliage is composed of true leaves that are fleshy and succulent. They are spatulate (spoon-shaped). Unlike the majority of cacti whose leaves are atrophied, Pereskiopsis uses its leaves to actively perform photosynthesis. They are a brilliant green and grow along woody stems equipped with areoles bearing spines and glochids (fine, irritating needles).

Its fruit is a fleshy berry, often globular in shape. Its color varies from yellowish-green to orange-red at maturity. The surface of the fruit is dotted with areoles which, like the stems, can bear small spines.

Pereskiopsis seeds are relatively large for cacti, measuring between 4 and 5 millimeters. They are light in color, ranging from whitish to pale brown. Their main characteristic is that they are covered with a casing, which clearly distinguishes them from the smooth black seeds of many other cactus genera.

- Uses:

The "Super" Rootstock: This is its number one use worldwide. Pereskiopsis is considered the best support for micro-grafts of young cactus seedlings. Its sap circulates extremely dynamically. Grafting a slow-growing cactus (such as Lophophora or Ariocarpus) onto a Pereskiopsis allows one to gain several years of growth in just a few months. It accepts almost all cactus varieties. Unlike other cacti, it tolerates humidity and frequent watering very well, which boosts the scion even further.

Traditional Medicine: In its native regions of Mexico and Central America, some species are used in folk medicine as anti-inflammatories. For this, the leaves are crushed and applied as a poultice to relieve joint pain or inflammation.
Do not use for medicinal purposes without seeking medical advice.

Soil Stabilization: Thanks to its robust root system and shrubby growth, it is sometimes used in Mexico to stabilize soil in arid zones.

Natural Barrier: Its numerous spines and especially its glochids (highly irritating micro-needles) make it an excellent natural barrier against predators or for delimiting spaces.

- Planting and Cultivation:

• Plant Graft cactus in a pot of approximately one liter.
• Use a very well-drained substrate based on sand.
• Water it copiously upon planting.
• Allow the substrate to dry out before the next watering.
• Warning: Never leave water in the saucer, as there is a high risk of root rot.

- Soil Type / Substrate:

Unlike desert cacti, Pereskiopsis appreciates a richer and less mineral substrate. A mixture of 50% high-quality potting soil and 50% drainage material (perlite, coarse sand, or volcanic rock/pozzolana) suits it perfectly.

- Exposure / Sunlight:

It requires very bright exposure but prefers slightly filtered light rather than the scorching direct sun of the full afternoon, which can turn its leaves yellow. A bright greenhouse or a south-facing windowsill behind a sheer curtain are ideal locations.

- Temperature / Hardiness:

This genus is strictly tropical and has no resistance to frost. It stops growing below 15°C and can perish quickly if temperatures stay below 10°C for a prolonged period. For optimal growth, it should be maintained between 20°C and 30°C year-round. It is imperative to grow it indoors or in a heated greenhouse during the winter.

- Watering / Water Needs:

Its water needs are significantly higher than those of classic cacti. During the growing period, the substrate should remain almost always slightly moist (but not waterlogged). If the soil dries out too much, the plant will lose its lower leaves. In winter, watering is reduced but should not be completely stopped if the plant is kept in the warmth.

- Multiplication:

Propagation is achieved through stem cuttings. Simply cut a stem segment, allow it to callous for one to two days, and then plant it directly into moist potting soil. Rooting occurs in less than a month in warm conditions. Sowing seeds is possible but much less common.

- Pests / Diseases:

It is particularly sensitive to mealybugs, which hide at the base of the leaves and on the stems. Red spider mites can also attack the foliage if the air is too dry, causing patches of discoloration. The main disease is root or collar rot caused by excess water.
