I am looking to try some "on the edge gardening". Im in what is said to be zone 3-4, but Id say its zone 4 myself. With proper multching, i belive i can bring the zone up to 5, and mabey 6, with other measures. Basicly, I would like suggestions, no matter how far fetched on what to try up here. If you ever wondered " i wonder how cold this can take?", or " I wonder how cold tolerant this actually is?", please let me know. Ill take any plant suggestions from, fruit trees, bamboo, palms, banana, ginger, decidious trees, pine, flowers, vines, ferns, anything. Im looking for mainly tropical looking plants, but ill take any suggestions. I would more then likley be posting updates on the plants as the year goes by. This is prompted by some information i recently read. It stated that the hardiness zones we use are made for trees basicaly. I would personaly like to know the limits of "tropical" gardening, and also the limits of certain species, with various types of wiinter protection. The growing season is from mid may or beginning of june to about mid september or end of october. The ground doesnt freeze till about end of december. I belive I have stopped the ground from freezing around my fargesia by multching when the ground was still soft. Id most likely build wooden boxes and insulate the plants on top of multching. Im crafty that way lol. So any suggestions, or help in anyway would be greatly appreciated!!!
