The match stick trick worked out nicely - one potato shoots leaves are almost double what they were before! Perhaps because there's some organic fertiliser in there with it.

Though I looked at the chart and technically it's not the time to put in potatoes in these parts, that's supposed to have ended last month. But...still going to do at least three more buckets. But also try to grow carrots and beetroot in them. Got alot of carrot seeds from plants that went to seed, including a heirloom that I must keep marked separately.
