Succulents grow best in a porous sandy potting soil, so amending your potting soil with sand is super important. You could use any type of sand, but to ensure fast drainage for succulents, I recommend buying a coarse sand rather than the really fine stuff.
Subsequently, what is the best soil mix for succulents?
Measuring Succulent Soil
The best mixing ratio of the three ingredients is two parts sand, two parts gardening soil, and one-part perlite or pumice. Translating this to cups makes it 3 cups of sand, 3 cups of soil, and 1.5 cups of perlite or pumice. The purpose of pumice or perlite is to aid in aeration and drainage.
Correspondingly, can succulents survive in just sand?
Now, while succulents can survive in sand, the only sand that will work is coarse sand. Succulents will not grow very well, if at all, in fine sand as it retains too much water, making it hard for the roots to breathe. Succulents in sand will not get as many nutrients as those grown in potting soil.
What is a substitute for perlite?
Sand is an excellent alternative to perlite because it does not hold onto water and provides sharp drainage.
Use perlite to root cuttings or grow cacti, succulents, epiphytes, and other plants that benefit from quickly draining soil with plenty of aeration. … Vermiculite is better suited for starting seeds and other situations when plants require plenty of moisture consistently available in their soil.
