Rootstocks

The MM106 apple and Quince A rootstocks arrived during the week, and have been heeled into a bucket of compost, waiting to be planted out. That was the first order of the day, so all but two apples are now safely planted in the nursery beds we dug on the hillside. We've put up the chickenwire cage that will protect all three beds from deer, and the rootstocks should now have a couple of weeks to settle in before we graft onto them.

Yesterday afternoon, we then drove the 22 tubes that will support the apple walk arches into the ground. These are 5/8" steel tubes, with the underground section cold-galvanized, and bitumen painted, for corrosion protection. They extend about 90cm above ground, and the rebar arches will slot into them in a few weeks. Alongside are the support stakes, that will ensure that the rootstocks don't suffer windrock while they establish.

Having got these carefully positioned, we then dug the two planting holes for our sweet chestnuts, which are on the same order as the twenty apples and one pear (the last two apples for the walk are amongst the grafting set). This was astonishingly easy: we each went to one hole, planning to get started then reconvene once we knew how difficult they were going to be—and had the holes dug in a few minutes. Working in the very stony (historically terraced) corner with the apple walk has clearly given us a different perspective. The holes dug, I drove an 8' stake for each; this has the advantage of being able to see the position from the house, to check that they seem right.

The two trenches of the apple walk then needed refilling, so we poured in seven bags of sand, to help drainage, and eight trugs of compost, before scraping the spoil heaps back into the trenches. Even with the additions, the loss of all that stone from the trenches means that they were still underfilled.

To make up the shortfall, we've used loam from the stacks of turf we've been building in the copse while lifting turves from the quince, sweet-pea, and copse beds. Trenches topped up, we then decided to put up the chicken-wire cage for the applewalk, having previously thought of leaving it until after planting. However, with the centre of the walk now clear of soil (but still muddy and slippery), we decided there was good enough access, and the greater risk was of kicking a tree over while manoeuvring the heavy roll of wire net. The corner stakes aren't really secure enough to tension a fence (I couldn't drive them deeply enough into the stony soil), but they've sufficed for getting the protective cage round the apple beds. We also had to dig one or two more short drains, to ensure that the ground isn't too wet—the very wet weather of the last month means there are several stream flowing down the hillside, in the main gullies and land-drain, and the ground just inside the gap in the wall is a pond. Fortunately, all our drainage work last year seems to have done the job well, and the existing trees seem protected from the worst of it.

The fruit trees are scheduled to arrive this coming week, and so we should be able to plant up the apple walk next weekend, at long last.
