These trees are yearlings (Maiden Whips), grafted onto M26 semi-dwarfing rootstock, and are lovely specimens with plenty of growth. Liz Copas, in her excellent book 'A Somerset Pomona - The Cider Apples of Somerset', describes Tremlett's as '...difficult to manage, being full of vigour...' which probably explains the size of these trees. Anyway, the planting season is getting late, so in they go, and this is how I did it...
The hole needs to be big enough to easily take the roots without bending or distorting them, and deep enough to plant the tree at least as deep as it was before being dug-up at the nursery. Seems obvious I know, but the planting depth is quite critical. Too shallow, and established roots will die off hindering
Once the hole is dug, a stake can be driven in with a lump-hammer, and I like to sprinkle a handful of bonemeal around the hole to help with establishing a good root system. Some people add organic matter to the hole, but my understanding is that this tends to promote excessive top-growth, whereas I want the tree to spend it's first year putting down a firm anchor of roots. The bonemeal needs forking into the soil so that it doesn't burn the roots with direct contact.
The final task is 'tipping-back' the leader. By pruning the first year growth back to a bud, and pinching out the two buds below it, we aim to encourage the tree to send out lateral branches lower down, and strong central leader growth upwards. That's the theory, and only time will tell if I've got it right with these new trees.
