| I have planted few white and dark red Dahlias this spring and they grow very well. They are standing very tall and wide with nice green leaves. Unfortunately, all flowers look dry and yellow even before they get opened. (Just like an old flow would) What is wrong with my flowers? Thank you. |
| Based on your description I am not certain what is happening to your dahlia flowers, however it might be due to a cultural problem such as overly dry soil. Dahlias in bloom need a generous amount of water so the soil stays evenly moist and never dries out. It might also be a pest such as broad mites, or a disease such as botrytis which causes the flower to shrivel and turn gray and fuzzy, this is most prevalent during damp or humid weather or can occur with overhead watering. I would suggest you consult with your local county extension to get a more specific diagnosis and based on knowing that, determine how to proceed. If it is something that requires a chemical control, they will have the most up to date information on what to use and how/when is best to apply it. |
