The Q&A Archives: Why geraniums never grow well

Question: I have planted many flowers this years, as every year. (By the way, I love the selection at Home Depot). Anyway, they are all growing nice, except for my geraniums. Every years, they start out nice. I feed them plant food, just like the rest of my flowers. They get sun in the afternoon. I pull off all of the dead ones. But half way throught the summer, like now by the end of July, all the blooms start dying and they look really bad. What am I doing wrong. My other flowers are flourishing. Thank you.

Answer: There are several possible reasons why this could be happening. One is that the summer turns hot -- too hot for some varieties and they will stop blooming as a result. Another is that you are possibly overfertilizing with nitrogen. This can cause excessive growth of leaves at the expense of flowers. Another possibility is excess humidity, especially if you wet the plants rather than the soil when you water and you are watering often. (It is better to apply the water directly to the soil and water deeply but less often.) I hope this helps.
