Sun Gro BLACK GOLD Moisture Supreme Container Mix

No, you do not need to add fertilizer immediately. This mix is pre-fertilized with a controlled-release formula that feeds your plants for up to six months.

It is designed for both. While it excels in outdoor hanging baskets and window boxes due to its moisture-retentive properties, it is perfectly safe and effective for indoor container plants as well.

These ingredients are included to balance moisture retention and drainage. The coir helps the soil hold onto water longer, which is critical for container plants that can dry out quickly, while the peat moss and perlite ensure the roots still get the aeration they need.

RESiLIENCE® is a proprietary additive included in this mix that helps strengthen plant cell walls. This leads to better root development and improved overall plant health, making your plants more resilient to environmental stress.

The inclusion of perlite and pumice helps prevent compaction. These ingredients create air pockets within the soil structure, ensuring that roots have room to grow and breathe even in smaller containers.
