Kangaroo Paw, Black leaves?
Hi there, i had bought this A. viridis, last year in a one gallon, well i had an outbreak of white fly's so i sprayed everything, used neem oil and Bayer advanced 3 in one mix and spray, when the neem oil stopped working. Also it got to be about 34 degrees here during this winter. Now i noticed the blackening almost a few weeks after i sprayed, could this be a burn, or fertilizer burn, or frost damage? The new leaves and flowers seem to be coming out just fine. Also its not really spotted, its more of like the tips were dipped in black paint? Any suggestions?
