Last Thursday (the 8th of October) I went on a tree mission to Wigtwizzle with my sister. Mission objective: to collect nuts from the massive sweet chestnut (Castanea sativa) there for treeblog Set D.

While a lot of unripe cupules were stillon the tree, a great many ripe ones were lying open on the ground below. While trying to avoid a nettling, I managed to gather a haul of chestnuts with a total fresh weight of 75 g (2 ½ oz). Mission accomplished!
The Set D sweet chestnut haul. Third time lucky?
I collected nuts from the same tree in 2007 and 2008 for Set B and Set C respectively, but I didn’t manage to grow a single seedling. I now know the error of my bad old ways; I erred by waiting until spring before planting, by which time the chestnuts – which lose moisture rapidly and so are unsuited to storage – would have been well and truly dessicated. This time around, with only two days passing between collection and planting, treeblog might finally produce some baby sweet chestnuts.
I planted one hundred of the nuts yesterday in five forty-individual-pockets-to-a-tray seed trays using a special seeds and cuttings compost from B&Q. I ran out of room (and out of compost), so I had about sixty nuts left over. Until I decide what to do with them, I’ve mixed ‘em with some damp compost and popped ‘em in a plastic bag.

The final product: five seed trays with one hundred sweet chestnuts carefully picked and planted. This is treeblog Set D(c) - the chestnut part of Set D. Set D(b) – the beech part – was planted on the 30th of September and the rowan seeds – Set D(r) – have just begun pretreatment and are on schedule for a springtime planting.
The 10th of October 2009 = Set D(c) Day 0.
