We love to use this amendment for adjusting our course soil here in St Maarten. Adding a 50\50 mix of this Lambert LM-3 All purpose to your local top soil can work wonders for your plants in your garden. Lambert LM-3 All Purpose Mix is formulated from a blend of coarse Canadian sphagnum peat moss, coarse perlite and medium vermiculite. This substrate is an excellent general or all purpose media. A Lambert Classic Mix!
