Earlier I posted about aphids entering my balcony garden. They affected the lettuce (which we removed), and were spreading to the tomatoes. We then discovered them on the morning glory vines. I had submitted to defeat figuring there was too much vine for them to eat it all, but lo and behold, nature provided its own solution with the sudden appearance of ladybug larvae, which eat aphids! They are crawling all over the morning glory, like guardians of the vine. A little ecosystem in itself, the balcony garden finds its balance. This also gets me thinking about how balcony gardens/rooftop gardens may seem removed from nature below, but they are just as subject to its forces as more traditional ground level gardens.
