Perfect for Jungle Plants or Aroids like Anthurium, Alocasia, Dieffenbachia, Monstera, Philodendron, ZZ plants, as well as Calatheas, String of Hearts or Turtles, Dracaena Dragon Trees, Hoyas, Palms, Pothos, etc. Also recommended for the ever popular winter indoor plant, the Christmas Cactus i. e. Schlumbergera species. This cactus and many Aroids listed above are epiphytic, which means they can be found growing up the side or in the branches and crevices of trees in rainforests as opposed to in the ground. WHEN SHOULD I WATER? Despite these specialized mixes containing more chunky gritty components compared to other soil mixes, they hang onto moisture for the root ball effectively. No need to water more frequently! Generally for indoor settings with established plants, one deep watering every 10 14 days is usually plenty. Watering weekly will likely still lead to root rot if the root system doesn't get a chance to fully breathe between watering sessions. FUN FACT This mix utilizes recycled coconut chips and coir, an otherwise wasted byproduct of the coconut industry. Of the 50 million coconuts produced around the world each year, about 85% of the husks are discarded as trash. As a soil component, the ground husks offer excellent aeration and moisture retention properties while still providing a fast draining medium to reduce the risk of soggy soil and root rot for indoor potted plants.
