If the land feels bone - dry to the touch , this should become pretty obvious that your painted leaf is exceedingly thirsty .
If there ’s something I ’ve learn , the hard elbow room is to verify if the land is evenly moist and your poinsettia is healthy before you bring it home from the shop or nursery .

This systemic bacterial wilting will blight the crowns , bract , and leaves . It evidence first as brown cankers or prospicient , water - soak streaks on foliation .
Brown necrotic spots may appear on the parting before they fall off . face out for long sally along the stems as well .
Remove dissemble plant fabric immediately and increase aeration . Avoid overhead irrigation and keep temporary worker systematically above 60 ° F ( 15 ° C ) .
There is no effective chemical substance treatment for this . You require to get rid of the industrial plant or plant life section and bury them under the grime .
