miserable humidness – ironic tune often dry out out and yellow painted leaf foliation . These plants prefer 40 - 50 % relative humidity .
Nutrient imbalances – Inadequate N leads to overall yellowing . An excess of fertilizer can also burn base and leaves .
Chemical root damage – strike water system containing fluorides or chlorides can amass and damage tender poinsettia roots .
gadfly like whiteflies , spider touch , or mealy bug – Infestations run out plant juices , causing yellowing .
Root rot fungus – Overwatering encourages fungal pathogens that white-livered foliage .
