My beloved string of turtles is being taken over by aphids 😩 I’ve been waging war on them for going on two months, using a combination of diluted neem oil (full strength kills my plants) and physically plucking the buggers off my plant with tweezers. I was away for a week and they’ve come back with a vengeance, eating most new growth near the roots and causing bigger leaves to fall off. Does anyone have any tips for getting rid of these pests for good?
