How To Use

Pot Mulching
• To suppress the incidence of moss, liverwort and weed growth, spread an even layer of Melcourt Potting 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 trees and shrubs, when applied to the clean compost surface just prior to despatch.

In Growing Media
• Melcourt Potting Bark should be incorporated at levels of between 20 and 40% by volume with either peat, or its alternatives. Generally the higher the percentage, the more open and free-draining the mix will be.
• Melcourt Potting Bark blends easily with other compost ingredients whether mixing is by hand or machine. It has very resilient structure, but as with all compost mixing, it is important not to over-mix, as this can easily break down the structure of peat and other ingredients.
• No additional fertilizer on top of normal additions is required, other than supplementary nitrogen in some cases.

Typical Crop Applications
Nursery stock, containerized trees, conifers, pot plants, pot bedding, herbaceous perennials, alpines, tubs and hanging baskets, interior landscaping, street planters etc.

Crop Management
The addition of Melcourt Potting Bark does not require any changes to the normal regime of crop management, although as the compost mix will have a more open texture, some users may find that they require slightly more watering.

Direct Sticking
Use up to 30% in a mix with peat or suitable alternative. No alterations to normal fertilizer additions or supplementary nitrogen are necessary
