You need to have a large enough potted plant for the Aqua Globe to stay upright. If you can't stick it in deep enough it falls over. I had problems with it getting clogged with soil. Even for the one plant, I was able to use it in, I didn't notice that I had to water the plant less then I normally did. I also didn't like how it looked in the potted plant. I felt it detracted from the plant's appearance. My Aqua Globes are all under my bed now. I'll sell them at a yard sale someday.
