Choosing the Best Substrate for Your Indoor Plants
Succulent and cactus plants require a substrate with excellent drainage, low water retention, and good aeration for their growth and survival. There are various substrates available in the market, but selecting the right one is crucial. In this article, we'll discuss the best substrates for plants like succulent and cactus plants, including their pros, cons, and usage.
