Six years ago, I planted two small dracaenas in pots with geranium, they have now grown 8 feet. One plant had slender leaves, while the other has broader leaves. The broader leaf plant has yellow spots that started about a month ago. The finer leaf plant has many new plants starting from the bottom. They are outdoors ,and my garden patio in Vancouver is very sheltered. What can I do about the spots, and when and what should I the plant with babies? I am new to container gardening, and would appreciate your help. Thank you M Chenier
