Answer: Unfortunately, based on your description I am not able to diagnose the problem. It might be a pest or disease issue, delayed response to the dry summer, or even the result of being root bound due to poor planting technique. I would suggest you consult with your local professionally trained and certified nurseryman and/or your county extension to obtain a specific identification of the problem. Based on knowing that, you can determine how to proceed. If it is something that requires a chemical control, your county extension will have the most up to date recommendations on what to use and how/when is best to use if for maximum results. Any time there are needles browning and dropping it is best to identify the problem and treat appropriately as soon as possible, so do not wait on this. I hope they can be saved.
