Geraniums looking unhealthy
The past two summers, my potted geraniums have not done well. I purchase large, healthy plants with nice blooms in the spring, and they do well until July. Just like last year, they are now producing just a few small blooms and the leaves are yellowing. The pots they are in are large and drain well. I've tried fertilizing, watering more, watering less, etc. The plants are all in bright sun. It's been extremely hot the past few weeks, but geraniums belonging to neighbors still look great. What am I doing wrong?
