Crop Management
Propagating media containing Propagating Bark are ideal for use with any type of management system, including mist, fog, and/or polythene. No changes to crop management should be necessary, although it is important to be aware that the medium may be more open than a peat/grit mix and may therefore require slightly more water.
Pot Mulching
• To suppress the incidence of moss, liverwort and weed growth, spread an even layer of Propagating Bark at a depth of 1-3 cms depending on pot size, on the clean surface of the compost, just after potting.
• This product can also be used to improve the appearance of retail shrubs and perennials, when applied to the clean compost surface just prior to despatch.
