If only the smallest buds at the very end of the flower stalk dried up dead, most likely it is due to not enough energy(nutrients) stored within the plant to support development of all buds. If every single bud dried and died, it is because of inappropriate fertilization after flower buds are set OR air humidity is relatively too low in Edmonton houses for your particular butterfly orchid cultivar. For your other one not developing flower buds, reasons could be either it is not mature enough or that cultivar particularly needs a low temperature stimulus (around 12.C night temperature for over 2 weeks) to initiate a flower buds development.

如植株能在最理想条件下生长,譬如充足光照(散射光)适量肥效,高湿(空气)环境,就自然健壮,能量充沛,达到最高开花率,没有温室环境,在爱城是接近不可能的。假若植株不壮(只有2至3片叶),复花是比较困难,如果叶数有5以上而未能长花,试施以较高磷肥後再以低温刺激2至3周(如前帖所述)切记见花蕾後停肥,不然会落蕾。
