SylvaGrow® Organic is based on a formula of fine bark (from sustainably managed UK forests), green compost (carefull sourced and certified) and coir (from ethical sources).
Melcourt has also thrown in some balanced organic fertilizers and seaweed meal for excellent vigour and disease resistance.
If you want to maintain your growing as organic whilst using the soil you'll need to make sure you only use fertilisers, pest control and seeds that have been certified by the soil association.
The SylvaGrow® packaging has also been manufactured using at least 30% post consumer waste plastic and the bag is 100% recyclable (check regionally).
Green growing at its best.
