Having harvested a handful of new potatoes from the balcony the other week (and then having to deal with the ants' nest thereby uncovered), I then noticed that I still have a couple of seed potatoes left from earlier in the season, which whilst a little wrinkled look basically still sound. Then, I came across a blog post talking about planting potatoes entirely out of season for a Christmas harvest.
This fits nicely with my beliefs about experimental gardening, so I'm off this afternoon to dump the earth back in the potato-box, and see what happens. I will report back.
In other balcony-gardening news: the red arrow-head lettuce appears to be flowering and setting seed (much to my pleasure), as is the dill (which pretty much just bolted the moment it was a real plant). I shall try planting some more of both.
The cherry tomatoes are doing well (2--4 to harvest daily, which isn't bad at this time of year), and are still busily setting more of themselves. I am tempted to try planting seeds from the earliest-growing one (a Peace Vine Cherry), to see if I can get a second batch of plants to provide a late harvest. It might, of course, just be a late harvest of green tomatoes; but this would suit me fine, as I very much like green tomato chutney and I've just eaten the last of last year's.
