你的杜鹃花要在夜间温度40° and 55° F的情况下养5-6周,而且什么时候室外,什么时候室内,什么时候浇水、浇多少水都有影响。你看看下面这段话:$ m, ^( g9 f J. b. p7 a& T4 y" @
your azalea will need 5-6 weeks of night temperatures between 40° and 55° F. Some or all of this temperature requirement can be met outdoors in the fall depending on the year. However, when frost threatens, the plant must be moved indoors and grown under a cool night regimen. That's the tricky part. Warmer temperatures will cause a skimpy supply of flowers. Without a high enough level of humidity around the plant at this stage, the buds may be deformed. Tiny green shoots may develop. These should be removed for aesthetic purposes.

Once flower buds are well developed, after 5 or 6 weeks of "cold treatment", move the plant to a sunny window and repeat the same instructions given in the paragraphs under "Getting the Most Out of Your Blooming Plant". The azalea should bloom again for several weeks in its new location. |
