Thanks mate, yeah the soil mound is higher than the grass level now and I've left a trench between the grass and the mound and it seems to drain very well so far. I've planted nine maples in there so far, I'll take another pic once I've finished planing them out.looking good with all that added grit and compost it must be slightly raised now anyway so should be great for your trees the compost will get those tridents fattening fast.Congratulations on a job well done
