Questions from You: Aphids
Anna asked: I had many aphids on collard greens and when I pulled the greens thousands of aphids went into the dirt. If I plant in the same bed, will the aphids or their eggs harm the new crop or are they dead forever?
Greg’s Answer: Anna, great question. First of all, as it gets hot the greens (collards, kale, etc.) are approaching the end of their lives and are so more susceptible, and even attract aphids. So the mere fact that it is hot outside will cause aphids to show up. As for the aphids – once they are on the ground they are pretty much gone. You can use a hose to wash them off or some soapy water to treat them with, but your biggest success will be to build healthy soil so that your plants get the nutrients that they need to grow healthy, since healthy plants are less susceptible to pests and disease.
