C. dowiana problem leave and spike
Last week i was excited as i see the first probally spike in my dowianas. But 3 days ago with the starting of the drop temperatures in the night i see a bit of black in the leave, and i start to put sulfur soluble.
Sudenly to night i see black in the what can be the point of the flower spike.
So supoussing are fungus i have used Fosetyl-Aluminium 30%.
Do you think is better cut the leave? is good the treatment i start?
Thanks in advanced
