Kale (red russian) keeps getting aphids/donāt seem to wanna die. I have spritzed with 3:1 / water : apple cider vinegar solution last week and last night with 3:1 / water : cooking vinegar (5% acidity) solution Is trying cleaning vinegar (30% acidity) at a 3:1 dilution worth trying? Should I try replacing soil/treating it with something? Either way I need to eradicate the aphids before these plants go back outside in 10ish weeks. Who has alternative methods for aphid removal. Airflow is good/plants have healthy indoor air circulation and the plant (2ish feet tall) is otherwise healthy. I donāt want the infestation to spread. Iām running out of leaves to just chop off!
