I immediately sprayed the strawberry plants down with an organic insecticide soap by Safer Brands. I sprayed directly at the infected areas as well as the tops and bottoms of the leaves. I checked the other strawberry jar planter, which didn't look like it was infested. I moved it to the other side of the balcony. I proceeded to spray the tomato plants that are placed near the strawberry plants just in case. Again, I sprayed the tops and bottoms of the plants.
Annoyed by the discovery of the tiny black infestation, I wanted to find out what I was dealing with. I eventually found someone else who had the same problem, and explained what the black bugs are - black cherry aphids! I was horrified...
We had a bad experience with aphids a while ago when we attempted to grow tomatoes on the balcony. Though I found a home remedy of mixing dish soap and water, the grossness of having to deal with the pests put us off from balcony gardening for a few years.
The organic insecticide soap seemed to have did the trick though for good measure, i'm also going to get some and release live ladybugs. Ladybugs are a safe solution to ridding gardens of pests such as aphids. The larvae and adult ladybugs eat aphids and other soft body bugs. Stay tuned to see how things are resolved...
