Almonds come from a hotter, drier climate than cool rainy Britain, but luckily my Robijn doesn't seem to mind too much. Because it flowers so early in the spring, however, it needs help with pollination; the majority of bees aren't out yet--too cold still. I've seen one or two bees this past week--and a few flies which can also pollinate--but to ensure I get a meaningful harvest, I've been hand-pollinating.
Two years ago I hand-pollinated and got 25 almonds as my very first harvest. Last year I didn't: it was raining; I didn't want to go out there! But as a result, I only got four almonds total. This year it's rained, but luckily it's also been sunny; I've been out most days with a feather, pollinating all the flowers I can reach. The tree is probably about eight or nine feet tall now, so I can't reach all of them--and I'll probably prune it down this summer back within reach. But I hope for a good hundred or so almonds this year. I may have to invest in a sturdy nutcracker.
