Dear All, I am a relatively new balcony microgardener, I have some potted plants and I group about 5 of them together in a standalone planter. I am worried if they are too close and not enough space between them because some collages are overlapping and touching one another. How far apart should my pots be? They are all in an individual pot, I don't think they need to compete for nutrient. Will not enough spacing affect their health? I just notice I have 6 of them being invaded byealybugs, this didn't happen before I scattered them around with huge spacing. I have attach a pic here, that is how they look. much appreciate your advice. Michelle
