How it happens

  1. 2-3 days before blooming, well-developed flower buds become parchy, they dehydrate and the green stems become reddish in color.
  2. Slowly it becomes evident that the buds will be aborted.
  3. The phenomenon is very strange, especially when it happens to buds situated in the middle of the clusters, while open flowers and end buds remain healthy.

Why it happens

  1. An orchid aborts its buds due to a shock, mst often to a termic shock.
  2. When exposed to temperatures under 10˚C, the plant will abort buds that are just about to bloom, and it keeps opened flowers and smaller buds.
  3. This incident happens when you buy an orchid in the winter; the plant is exposed to clod while transported.
  4. Another dangerous situation for your plants is when you air out your rooms in the winter with the orchids placed nearby the window.

Other causes that hinder blooming

  1. You water your plants too much or too little.
  2. You keep your plant in a place either too dark or one that receives lost of glaring sunlight.
  3. You use too much fertilizer during the blooming period.


Once flowering begins, you must make sure that your plant is protected from temperature, light and nutrition shocks.
