Bonsai Care in Winter
Bonsai care in winter is a serious concern. All container plants need special consideration during winter - bonsai included. Indoors and out, there are many techniques to keep your bonsai safe.
Winter Care of Tropicals
If you live in the tropics, snow is rarely a problem.
However, when the cold does head south into tropical and subtropical regions, even a light frost for some plants can be devastating.
Growers in warm climates, often use 'plant blankets' (as shown above). This lightweight fabric can add 2-8 degrees F to the temperature, depending upon the type you use.
Plastic tents and many other creative protective arrangements are not unusual for even colder situations.
This photo is of a zip-up cover created from two drop-down sides of an old tent. Before it was zipped, I placed a bed sheet over the tree.
A word of caution - when using any type of plastic, always protect your trees with a layer of cloth or even newspaper under the plastic cover. Plastic conducts cold and direct contact can cause great damage.
If you can carry your bonsai, bring them indoors for the best protection!
Growing tropicals outside warm climates? A
small greenhouse
may be ideal.

Winter Care of Other Than Tropicals
These are Harry Harrington's bonsai under the snow in England.

While traveling, I've seen amazing 'plant pits', cold houses and half-in-the-ground preparations. However, winter in colder zones is not my field of expertise.
My suggested reading is Harry's excellent article on
Care in Winter.
