Question:
When I brought my dwarf citrus trees indoors for the winter, the leaf color changed. Now they are spotty and have little red dots, plus something like spider webs. How can I treat the problem?
Answer:Citrus trees are highly susceptible to mites. The first control tactic is to give them a good hard shower in a bathtub or other suitable place to dislodge the mites. You can also spray your trees with horticultural oil or insecticidal soap. Read the label and dilute the product appropriately for indoor plants. Otherwise, provide your citrus trees with cultural care recommended for indoor conditions. Do not overwater or overfeed.
