I have had issues with my Thai plant since I brought her home from Aldi. I have repotted her and done everything. I could figure out why she was losing all her leaves. I had originally thought it was the shift and temperature because she was being kept by an air vent. So I moved her, and she continued to lose all of her leaves. I have since noticed new leaf sprouting and been feeling very good about her. But today I found spider mites. Will a solution of water and isopropyl alcohol work to kill then and how often should I treat?
