Almost all the rest of the weekend has been spent installing proper land-drains on the hillside, to drain the orchard. When we planted the trees, two years ago, we only had time (and money) to dig open trenches to drain the ground, and they've remained so. That's been a little unsightly, but also made it awkward (even dangerous) to walk around the orchard, so it was only ever a temporary measure. The winter's the ideal time to do something about this, as the grass is dormant and shorter, the mess of sorting it out will be grown over in a short while, and the ground is wet—making it easy to check things are working.
The land-drains comprise an 80mm pipe, which comes with 15mm slits in it (two opposite each other, offset 90° with the next pair, about 10mm apart). The pipe gets covered in a polypropylene geotextile sock, which stops large particles getting into the drain and blocking it. Small silty particles pass through and get carried away, and the idea is that a permeable layer of larger particles builds up, improving water flow. Once this is laid in the trench, we've partly backfilled with 10-20mm gravel, and then covered it over. It looks a bit of a mess now, where the spoil stacks next to the trenches have been removed, and the trench is obviously bare soil. However, the grass will start growing quickly soon, and soon the lack of trenches and hummock-y spoil heaps will be a massive improvement. More important, practically, will be the much safer footing as I cut the grass with the brushcutter!
While we've been out, I also popped up to the birch clearing, and saw that a number of the snowdrops we planted last year have started to come up. Hopefully there'll be even more by next weekend.
