Soil Management for Indoor Plants

The video tutorial by Lee provides a comprehensive guide on selecting the best soil for indoor plants. It covers the functions of soil, such as nutrient feeding and water retention, and discusses various soil amendments like perlite and orchid bark to improve drainage. Specialized soils for specific plants, such as cactus soil for succulents, are also explored. The tutorial offers advice on soil maintenance, repotting, and the reuse of old soil, emphasizing the importance of transitioning plants gradually to optimal soil mixes to avoid transplant shock. Finally, it compares the benefits of buying premixed soil versus mixing your own.
