Yes, it is likely to very likely die within a few seasons, but not necessarily in winter.

Quote:

Species that have well-developed dormancy needs can be tricked to some degree, but not fully. For instance, if you give a Japanese maple (Acer palmatum) an eternal summer by bringing it in the house, it will grow continuously for as long as two years. After a maximum period of sustained growth, a temperate climate plant will automatically go dormant no matter what the season or condition. Deciduous plants will lose their leaves, evergreens will curtail all new growth. This is very stressful to the plant and usually fatal. It will be 100% fatal if the plant does not receive the necessary period of cold temperatures required to break the dormancy.***

From "What is Dormancy" on Brent Walston's Dormancy article (This link updated to reflect the original source of the quote with apologies to Brent)

Quote:

***Once buds are dormant, they will not resume growth, even under favourable conditions, until they have received: 1) first adequate chilling (exposure to low temperatures (2 to 5oC is typically most effective) for some minimum duration; then 2) an adequate heat sum defined in degree days, exposure to temperatures above some threshold temperature (To, often assumed to be 5oC) for a minimum duration of days. For example, a heat sum requirement of 100 degree days with a To of 5oC would be met by 100 days at 6oC or by 20 days at 10oC.

I intend to notify the owners of the website of this violation immediately. I encourage others NOT to frequent such websites that steal information for their content for purposes of drawing folks there to expose them to their advertising. I find this kind of behavior reprehensible. Brent

The ad contains a copyrighted image of mine from 2004. Not sure what the actual CD contains... yet! I updated the link and have corrected the inaccurate attribution to the Encyclopedia people. It would be helpful to me if you could edit to clarify your message above concerning the "quote being lifted without attribution", because it may be misunderstood by readers to suggest that <I> lifted it without attribution - actually I incorrectly attributed it to the source on which it was published. Apologies, Matt __________________ Want to be a seller on bonsaiAUCTIONS? Get authorized today! bonsaiTALK: Over 100,005.36 Megabytes Served this Month!

Posts: 310	Matt, et al The quote was illegally copied and used by the author(s) of the encyclopedia website. Matt had no way of knowing that this material was stolen, so his use of it is entirely innocent. That is a part of the greater problem of plagarism. Someone reads this copied 'good stuff' and passes it along attributing it to the thief rather than the true author. Use of portions of copyrighted material with proper attribution (citation of the author and publication) can be, and usually is perfectly legal and proper. I don't mind my material being used in that way for educational purposes. But when my hard work is stolen to draw others to a website for the purpose of making money through advertising, then I must take the strongest action to stop it. For the record, I regularly give permission to local bonsai clubs to reprint my articles in their entireity for FREE. I have only a few modest conditions. I don't think I have ever denied anyone use of my work for non profit educational purposes, but I regularly deny requests for permission to use it for profit. Again, to be clear, Matt and this website are not to blame. Matt could have used the same quote with proper attribution (if he had known it) and I would have had no objection. Brent
