Know before you buy
The chunk coir is included to prevent soil compaction over time. By maintaining a loose structure, it ensures that your roots have consistent access to oxygen, which is vital for long-term plant health.
Mycorrhizae are beneficial fungi that form a symbiotic relationship with plant roots. They effectively extend the reach of the root system, allowing the plant to absorb water and nutrients more efficiently while increasing its overall resilience to environmental stress.
Yes, this blend is excellent for containers. The combination of peat moss and perlite provides the high drainage and air porosity needed to prevent root rot in pots, where water can easily become trapped.
This specific PRO-MIX HPCC formulation focuses on the physical structure of the soil and the addition of Mycorrhizae. It does not include a heavy base fertilizer charge, so you should plan to implement your own nutrient program based on your plants' specific needs.
Because this mix is designed for high drainage and air porosity, it may dry out faster than dense, peat-heavy soils. You should monitor your plants closely during the first few weeks to adjust your watering schedule to the mix's specific drainage rate.
