This is the oca I planted last spring, sprawling all over the place. It doesn't do much until midsummer, then starts spreading. It's a South American root vegetable; the tubers swell as the shoots die back, so I won't be lifting it till all the top growth is dead, in late November or December. It's about my one success story this year, so I'm looking forward to it!
You probably remember that Hive 5 used to be very large, and nasty-tempered. About half the bees had a yellow stripe, and it was full of drones. I had a look yesterday. All the bees are black, and extremely quiet on the comb, just like Hive 4. I can only imagine that the queen, raised from an egg laid in Hive 4, avoided mating with drones from her own hive, and mated selectively with Hive 4 drones. These may have shared a mother with her, but will have had a different scent.
Hive 4 has lots of honey in the broodbox, so no worries about that one. I'll give it a gallon of feed with Fumidil-B in it, for Nosema, and that's all. Hive 1 is fine, but it doesn't have so much honey stored, so I'll give it candy just in case. It's a lot better off than any of the hives were this time last year, though. Hive 5 has some drones, so there's something for the new queens to mate with. I'll check them out next week and see what's happening.
