I've had a problem on two different characters at two different houses that my plant's needs are not showing up as icons over the plant. I've got a honey sickle plant that needs pollination and sun, but you only see that if you mouse over the plant. There are no icons at the top of it at all. After I fill one of the needs, the other ones appear. This makes it difficult to tend the garden without missing something, particularly if I've planted things close together.
