The bergmansia is effected the worst. I have killed them when my plants are small, but I can't hit every leaf of a grove of basjoo that are 10-15ft. tall. The grove is too dense and tall. So are the canna. I can spray and spray in them inside of the sunroom where they are stored and they come back faster than the plant can recover. I have also used systemics also. I have not sprayed for 2 years hoping that mother nature will balance things out with predators, but the damage just keeps happening. I used to have ensete that I would trim down and bring in for the winter and after 3 years they had 12ft. leaves. Now they just get killed in the winter by the spider mites. Any input would be appreciated.
