Wintergreens

Are easy to grow Plants especially during winter to compensate the lack of fresh supplies.

Onions

And Garlic tend to shoot if they feel comfortable, showing you that they are ready to sprout a bundle of fresh and juicy scallions. All you have to do is to put the onion in the soil and moisture.
A Creative Idea is this Onion Medusa created layer by layer.

Sprouts and Microgreens

There is a vast variety of Sprouts you can use as Alfalfa, Lentils, Radish, Mustard, Cale, Beans (not too many as they become a bit poisonous ), Pears, Amaranth....
Sow them directly in the soil , they dont need much more than a bit of light and being kept moist. You can start harvesting right away, the longer you wait the stronger the greens become in taste.

Sepp Holzer? Yeah that's the guy who grows Citrus in the Alps in over a 1300m altitude without the help of greenhouses. One of the principles he uses is the so called Hügelkultur he "invented".


Hugelkultur
Is simply rotting wood. Therefore a woodpile is covered with twigs and soil, additionally you can
fixate the whole Construction with L formed Branches you stick in the pile with the long end.
Now you can plant a vast variety of plants shrubs and trees.
The rotting woodpile easily absorbs and stores moisture for a long period, making this technique usable from the mountains to the desert, as water means life.
Fungus and all kinds of Creatures now start decomposing the nutrients stored in the wood over a long period of time.
