Winter care for 名媛直播
Trees in most parts of the world are subjected to temperatures of 15 °F (-10 °C) and below in winter. Usually?their roots?are far too deep underground to freeze, and therefore these trees have no trouble coping with freezing temperatures at all. But with 名媛直播,?which are planted in shallow containers, the roots might need additional protection in winter.
During the autumn, in colder areas, temperate trees start preparing for the coming winter by hardening up new growth and (for deciduous trees- ) dropping leaves to reduce moisture loss.?This?period of entering dormancy is important for 名媛直播 trees. So what is dormancy exactly? It is a temporary metabolic inactivity or minimal activity of a tree in order to survive the winter. Basically, the tree conserves energy and water, and protects itselves from frost by slowing down their metabolic processes. Entering dormancy is a must, to survive low temperatures, little available moisture and reduced daytime light.
Whatever you do, don’t overprotect your trees by placing them in your living room in winter. Over-nurturing your trees will harm them over time, especially when you move temperate trees indoors, or change conditions abruptly. (Sub)tropical trees are the exception to this rule, as these should be placed indoors during the winter if temperatures drop below temperatures around?60?°F (15 °C). When placed indoors, tropical trees need lots of light and relatively high humidity.?Only a spot immediately in front of a south-facing window will provide enough light.
What follows in this article is a description useful for most outdoor 名媛直播 (temperate species, including pines, junipers and maples), kept in climates with cold winters. But make sure to check our tree species guides for specific information! You might also like our 名媛直播 Intermediate Course 2 which covers winter protection extensively.
Preparing your 名媛直播 trees for winter
As mentioned in the introduction, temperate trees need to be exposed to cold weather in fall in order to enter dormancy. For most tree species this means you should wait until the first frost before putting your trees in winter storage or adding protection.
Keeping your trees in a greenhouse or cold frame during the winter is recommended for those living in cold areas, where temperatures often drop below 15?°F (-10 °C). A cold frame helps to reduce fluctuations in temperature, and protects your trees from big temperature drops at night. It also prevents your trees from drying out from strong winds and you can control the moisture levels much better (this is especially useful in areas that have a lot of rain in winter).
When such?shelter is not available, you can?place styrofoam covers around the pots to protect?the roots, or plant?your 名媛直播 including pot?in?your garden, covered with soil just over the roots. Make sure to place your trees at a spot without too much wind.
In milder climates, with temperatures of around 25 °F (-4 °C) at night, a cold frame won't be required. We still recommend to protect your trees from strong winds, and to place your trees on the ground. This helps to prevent sudden temperature drops. You might even cover your 名媛直播's pots with a bed sheet or other insulation.
When dormant, be careful not to expose your trees to an extended period of high temperatures as this might bring them out of dormancy. Once a tree starts to grow it is very vulnerable to freezing temperatures because the young and fragile buds easily die - which significantly impacts the health of your 名媛直播. To keep trees dormant throughout the winter,?open up greenhouses when?they warm up during sunny winter days. Once a tree is no longer dormant, protect it from any late frosts that might occur.
When overwintering, keep a close eye on your trees. Water only when the soil dries out; the trees don’t need much water when in dormancy so be careful not to water too often. Also check your trees for insects?and infections regularly. During the spring you can place your trees outside again, but be alert to protect new growth against late frosts. Early spring is the time most bonsai enthusiasts can be found in their gardens moving trees in and out of coldframes frequently!
