Climate change: evidence from my edible garden

My blueberry bush is suffering a few multiple-personality issues at the moment, probably due to all of the crazily warm weather we had in the last month or so. It's foliage is turning a beautiful red colour getting ready to drop off over winter, but at the same time the plant has flowers forming. The blueberry isn't the only thing I've noticed flowering or fruiting that shouldn't be. A couple of eggplants I had left in the ground as an experiment have small fruit just starting to show, and I picked some tomatoes today that have ripened only over the last month.

I'm surprised my blueberry is forming flowers already as I only planted it in September last year from a very small rootstock, and I also transplanted it from another spot in the garden only in the last few weeks so thought it might suffer a bit of transplant shock. The plant is still small; only about 30 cm tall. If the flowers don't drop off themselves soon I'm going to take them off to let the plant put more of its energy into growth rather than trying to form flowers and berries in the middle of winter. I am going to leave one or two flowers on though; I can't help myself cos I want to see what the flowers look like and also want to test whether the bush will actually go ahead and form berries even though it is so young and it's not the normal fruiting season. The blueberry I planted is Vaccinium corymbosum Northland variety which I bought from the Digger's club. I mixed some Azalea potting mix in to the soil when I first planted it, to try and create an acidic soil to emulate the pH of the blueberry's natural habitat in North America. I need to test the soil of the new spot and make sure it's on the acidic side. I am also going to plant a second blueberry this year to help with pollination, and also because I love and adore to eat blueberries so don't think one blueberry bush would create an adequate supply.
