What is bonsai tree?
For some the highest use of this wonderful tree is to grow it as bonsai. This ancient Japanese and Chinese art uses living trees to create beautiful art objects that can grace a terrace or a dining table. In Japan, houses have special niches for displaying objects and bonsai trees are often brought indoors to show their beauty. Bonsai is a specialized form of gardening that is not difficult but takes some special knowledge. Any Japanese maple can be used, from upright to cascading, and the training enhances the natural beauty of the tree. If trees are grown indoors as bonsai they must spend some time outdoors or refrigerated in winter to keep them healthy. In Japan bonsai trees are grown outdoors and only brought inside for short periods to admire them. Just as they do in the garden, trees as bonsai become more beautiful and more valuable as they mature.

How to protect Japanese maples from frost?
If frost is anticipated, draping a sheet or blanket over the tree so that it touches the ground may help trap heat close to the tree. Japanese maples cultivated in a container are often best protected if brought into a garage or other shelter. Improper or poorly-timed application of fertilizer can also lead to freeze damage on the Japanese maple. A new flush of growth usually occurs following fertilization, so if a nitrogen supplement is applied in late fall it will stimulate vulnerable new growth in winter or early spring.
What happens if a Japanese maple tree freezes?
Leaves may eventually drop from the tree and branch dieback can also occur. Major branch dieback leaves remaining branches and the trunk exposed to greater sunlight, leaving them vulnerable to sunscald and creating injured bark areas that certain pests and fungal pathogens can penetrate. Generally, a freeze-damaged Japanese maple will begin to produce new growth from surviving branches within a few weeks, though this new growth is often weak and spindly.

How much below freezing did the temperature dip? We have had a couple of frosts here which have destroyed all the Magnolia flowers, but not cold enough to affect the Japanese maples, fortunately.

I too experienced the late frost in Maine and all the leaves on my Japanese Maple are wilted. The color seems to have held but they all have the droops. I just planted this tree last year and I wish I had known to take preventative measures. With our extraordinarily early spring many plants are leafed out that normally wouldn't have been.
