A loose, well-drained mix helps Selenicereus anthonyanus maintain healthy roots while still holding enough moisture and organic matter.

Native to southern Mexico, Selenicereus anthonyanus grows in warm forests rather than dry desert ground. It often lives with loose organic debris around its roots, where moisture is available but excess water drains away quickly.
That background explains the best soil for Ric Rac cactus: airy, well-drained, and lightly moisture-retentive. A sandy-loamy texture with some organic content suits its relatively fine roots, which need oxygen as much as steady access to light moisture. Slightly acidic to near-neutral conditions support healthy root function.
A homemade mix gives Selenicereus anthonyanus the balance of airflow and light moisture retention it needs in containers.
The finished blend should feel springy and crumbly, not heavy, and excess water should pass through without the container staying soggy.
A slightly acidic to near-neutral range of about 5.5–7.0 suits Ric Rac cactus well. Within that range, essential nutrients stay more available to the roots and are less likely to become chemically locked in the mix.
Selenicereus anthonyanus generally handles mild variation, but extremes on either side can reduce nutrient uptake over time. If the mix stays near the middle of this range, root function is usually more consistent.
This cactus is more likely to struggle in stale, compact media than in an open mix. Soil may be a factor when growth slows or the root zone stays unevenly damp.
Dense soil holds too little air and dries unevenly, so gently loosen the top layer and check whether the root zone has become packed.
If the container remains heavy for several days, the mix may be breaking down, so pause watering and assess texture and drainage.
Very dry organic material can repel water at first, so moisten it gradually and make sure moisture spreads through the full root area.
White crust on the soil surface can point to mineral accumulation, so scrape off the top layer and flush with clean water if drainage is good.
