Pachycereus pringlei – Pachycereus pringlei – Fatty plants – Pachycereus pringlei – Succulent

genus which includes 10-12 species of columnar cacti originating in Central America. They are very long-lived and the centenarian specimens, in nature, can reach remarkable dimensions, even close to twenty metres of height, even if their growth is very slow.

The stem is dark green, sometimes bluish or greyish; they have 10-15 ribs, covered with areoles carrying numerous grey thorns; with the age they tend to branch out a lot, assuming the appearance of a “bush”, whilst the young specimens usually have a single stem. In late spring, they produce numerous flowers of white or green colour, followed by fleshy fruits, covered by thorns; in the reddish or pinkish pulp, you can find several small black seeds.

Over the years the plants tend to lose their spines and to mean at the bottom of the trunk. The most common species is the P. pringlei.

Pachycereus

Exposure

Pachycereus the best position to grow a pachycereus and without doubt the full sun, although the plant does not present problems even in slightly shaded positions for a few hours of the day. It fears the cold, therefore, in winter, it is to be kept in the house or in cold greenhouse, or, at least, in places where the temperature does not drop below the 7-10°C. The very large specimens can bear short periods of frost.

Watering

water sporadically from March to October, allowing the soil to dry perfectly between one watering and the next. In winter, avoid watering, especially if the plant is kept at low temperatures. During the vegetative period, provide potassium-rich fertilizer every 25-30 days, dissolved in the water of the watering.

Other advice

Soil: prefers rich, deep and loose soils, many well drained. Use universal soil mixed with sand and lapillus. These plants develop a fairly large root system, and often reach a considerable weight, and are therefore to be kept in fairly large pots, repotting them every year.

Multiplication: by seed, using fresh seeds; before sowing, it is advisable to gently pass them with very fine sandpaper, to promote germination; the seedbed should be kept in a shady and humid, but very hot, place.

Parasites and diseases: Cochineals can cause varying degrees of damage.
