Hi Magpie......... yes winter certainly has hit now hasn't it. We do get the odd tinge of a frost........ a friend visiting from Christchurch last winter corrected me in saying it was just a cold dewy morning.... he scoffed at my frost. Mind you.... so do the pests and bugs
Your right the cold certainly does clean up the garden doesn't it. I seem to freeze in cold weather and find it hard to get going.... your -6 is mighty cold... what a lovely pest free garden you must have
Shiney... I'm growing in the small family orchard multi grafted apple, Mandarin, orange, grapefruit, lemons, ( Tahitian and kaffa) plums, lime, Macadamia nut, Feijoa ( pineapple Guava), red and yellow guava, gooseberries, figs, tamarillo, blueberries, raspberries, orange berry, loganberries.... and no doubt something I've forgotten.
In the market garden part that I'm developing for a business I'm planting
Figs, Sweet Navel Oranges, Easy Peel Mandarin and Plums.
The aim is to be picking fruit all year round for us to eat and to sell at my local farmers market. Our climate is so mild we can grow fruit from both subtropical and temperate climate... very nice 8)
couscous... no we don't harness any hot water..... you need council permits( revenue collecting) and the like ( to stop people over using the resource I guess)
You have to drill quite deep I hear and it's expensive. It's very mild here and it rains aplenty so we've not looked into it.
Do they garden in Iceland? Very short growing season I bet...... I don't imagine you'd see many fields of corn or the like

It takes both sunshine and rain to make the garden bloom.
