Indoor cacti have become a popular choice among plant enthusiasts due to their low maintenance and striking appearance. Although these plants are easy to care for, cacti still require the right type of soil and fertilizers to thrive. A balanced fertilizer specifically formulated for cacti and succulents can provide essential nutrients in the right amount. Along with keeping the plant healthy, a good soil mix and fertilizer can also promote seasonal flowering.

Understanding the needs of indoor cacti
Cacti flourish in arid conditions, so to replicate the environment indoors, careful attention has to be given to the soil composition. This type of plant prefers well-draining soil that prevents waterlogging, similar to dry, sandy soils of deserts.
Key characteristics of the best soil for cactus indoors:

Porosity
Cactus soil should be porous, which allows excess water to drain quickly—over-watering results in rotten roots, the most common reason for the plant to die. Hence, overly moist conditions should be avoided.
Aeration
Adequate air circulation around the roots is essential for the plant to thrive. To ensure this, use loose sandy soil to plant your cactus.
Nutrient content
Cacti require some essential nutrients for optimal growth. So, it should be planted in mineral-rich soil. Since these plants are kept in pots, the soil needs to be replenished with the required minerals from time to time. If you have Christmas Cacti at home, adding proper minerals to the soil in the required quantity is essential for their growth and flowering. One of the   best fertilizers for Christmas cactus   can be easily made by dissolving charcoal in water.
pH level
Cacti prefer slightly acidic to neutral soil pH levels, typically ranging from 6.0 to 7.0. Maintaining the appropriate pH ensures the proper growth of the plant indoors.  

The right soil mix for cactus
It is essential to follow proper care guidelines to ensure the plant’s health and vitality. The ideal soil composition for cactus growth is as follows:

50% coarse sand or perlite for providing drainage and preventing compaction
25% potting soil, which will offer nutrients while maintaining a loose structure
25% gritty material

These components have to be mixed homogeneously before potting the plant.
