The problem at first I thought it is lack of water.
After a while the problem was getting worse.
The leaves look really bad and the tip of the new growth was stunned for almost a month until I used a systemic insecticide.
Appeared to be some aphids and some other tiny flies.
Even if the plants have managed to then put some flower buds the new leaves still do not look good.
Does anyone k be ow what it is?
Could it be several mite species or a virus? Or all at the same time?
It is happening to several Eupatorium plants.
