Know before you buy
The addition of limestone helps balance the pH of the Pinus radiata bark. This creates a more stable, neutral environment that prevents the substrate from becoming too acidic over time, which is essential for healthy root development.
The 6-9mm small grade is ideal for orchids with finer root systems, such as Oncidiums or Miltoniopsis, as well as young seedlings. If you are potting large-rooted orchids like mature Phalaenopsis, you may prefer a larger grade, though this size still provides excellent aeration.
Yes, because the bark is wind-rowed and slightly composted, it is highly resistant to decomposition. It maintains its structure and air pockets much longer than standard fir bark, meaning you won't need to repot your plants as often.
Absolutely. This bark is an excellent amendment for aroids like Philodendrons and Monsteras, or as a drainage layer in terrariums. Its ability to hold moisture while maintaining high airflow makes it a versatile choice for any plant that requires a chunky, well-draining medium.
No, this bark is specifically processed to minimize salt accumulation. You will find that you need to flush the pot significantly less often than with lower-quality bark substrates, simplifying your overall maintenance routine.
Four quarts is equivalent to 0.14 cubic feet. This is typically enough to repot two to three standard 6-inch orchid pots, depending on the size of the root ball and the amount of old media you are replacing.
