What are hardy bonsai trees ?
Hardy bonsai trees are bonsai tree species that can withstand even the lowest temperatures in winter without any problems. They are genetically adapted to frost. Hardy bonsai trees are usually called outdoor bonsai or garden bonsai.
Although these hardy bonsai survive well, they should (with a few exceptions) not be overwintered outdoors in winter. During frost, the bonsai soil is frozen in the bonsai pots and can no longer deliver water. Despite the pronounced hardiness in winter an outdoor bonsai can be damaged by the lack of water.
The problem of water shortage on frozen ground can be avoided in winter hardy bonsai trees by hibernating in an unheated greenhouse or foil tent. Digging in of such bonsai in the garden soil (shady, wind protected) works very well.
In any case, you should avoid the overwintering of outdoor bonsai in the house or even the apartment. It is too dark and, above all, too warm. The outdoor bonsai consume their reserves under these conditions and become weaker. Possibly they even sprout out. Then even the hardiest bonsai trees become frost sensitive and can be damaged even at temperatures just below 0°C.
Wintering of outdoor bonsai
Most outdoor bonsai, properly maintained, can withstand temperatures of -15°C in winter without any problems. They're winter-hardy. This means that they do not have to be protected from low temperatures.
Do you still need protection ? Yes. They must be protected from drying out if the soil in the pot is frozen.
