Hole with tree now filled with a wet mix of rotted farmyard manure and the soil from the hole to ensure the tree gets lots of mitochondria from the woodland soil nice and close to the roots. This method also locks the tree into the ground so a post is usually not needed unless it's in a particularly windy spot.
Newly planted beech tree now safely in the ground with forest floor replaced. Lots of bluebells around it (the green stuff that looks like grass. There's no grass there at all). I only have to surround the tree with brash (spiky branches to keep the Roe Deer off it) and it's good to go. Unless the summer is very dry, I'll not need to revisit the tree again as all the planting materials are biodegradable.
Freshly unearthed hedging plant in a wheelbarrow with a trug of water an manure, about to go to it's new life in the woodlands as a proper tree. Not a bad root ball on it - it's been constrained to the original hedge trench, but plenty of feeding roots and this is the least-good of the bunch, too. It has a prime spot in the woods in a clearing near a mature beech next to the now rotted remains of an oak stump.
Got given a small beech hedge. Only proviso is that I have to dig it up. They don't like being dug up. Here's one in the #bluebell woods in its new career as a proper beech tree. I use the postfix method of setting them. A trug of manure, soil from the hole and a lid of topsoil with plants intact.
