去年买的一品红, 顶上的叶子是红的。 今年夏天老叶子掉了,发出来的新叶子都是绿的。 不知道这个红叶子是发出来得时候就是红的呢,还是绿叶子老了变红的?眼看就到圣诞节了,一品红为什么还不红?
Sorry, I can not type chinese now / e( u2 w6 D4 v 7 i$ q" |. x% }7 A. SBut, I put the poinsettia in a seperate room which should have more than 10hrs black time. Maybe it need more sun light?
at least 10hrs darkness, you can treat it 10~14hrs or longer ,it does not a matter, just a couple of hrs of sun light. and hopefully it can change corlor 3 weeks later till x-mas day.
