Various types of leaf deformation may occur on poinsettia. Often, the damage begins when the leaves are very small. As plants grow, the mature leaves cover the damaged young leaves, so plants are still marketable.

Easter falls on April 16 in 2017, a late Easter date. Just as in the late seasons of 2014 (April 20), the 2017 schedule provides plenty of time for proper bulb programming as well as some extra time that growers will need to factor into their spring production plans. Last year, Easter fell on a very early date (March 27th) and growers had to push hard all the way to the end to time the crop out properly. Pushing a crop hard to make an early Easter or pulling back hard to slow growth for a late Easter is not ideal and can diminish quality.
