Advice from our specialist

The key for the selection of growing media for foliage plants is based on the plant variety and container height. Tall containers provide a greater column of growing medium and drain well; therefore, a growing medium with a high water holding capacity is needed. Shorter containers have a lower column of growing medium and a greater saturated zone; therefore, a growing medium with a lower water holding capacity is needed. However, since foliage plants tend to be top heavy, a growing medium with a high bulk density is needed to stabilize the container. This is where bark mixes work best. They provide a low water holding capacity and a higher bulk density compared to peat-based media. If high drainage and weight are required, PRO-MIX® BRK works best. For a slightly lower drainage capacity and greater water retention, PRO-MIX® BRK20 may be more suitable.
