| Hello. I have Tall garden phlox in many areas of my yard, but a couple sets of them are not looking good. The leaves are curling inward and the stalks are very limp and sometimes just break off. They are not standing up like they should. They are 3 years old. What could this be? I don't see any signs of insect damage, it is not hot or drought here, we have had a lot of rain this week, but they have been doing this for about a month now..Thanks for any ideas. I don't know what to do about it. Sorry, cannot get the pic to rotate for some reason. |

| Hmmm, I might even be tempted to cut back the top growth since they look a little frail and prone to flopping. There is plenty of time for them to catch up and grow a bit bushier and self-supporting. Phlox are terribly prone to fungal diseases, especially leaf-spot and tobacco mosaic virus, as well as my nemesis, eelworms. Also, lots and lots of rain can increase nutrient lock-up (and some of your leaves look a bit chlorotic). An application of sulfur might help or a copper based fungicide. Dig these up next year and divide them - phlox really need this every couple of years in order to maintain vigour......and yes, if you decide to remove them, excavate carefully and check for either voles, weevils or other ground based pests, along with any signs of fungal presence (yeasty smells, fungal hyphae). |

| Jean001a..there was an herbicide sprayed about a foot away, the bottle said safe for plants. I dont know what my neighbor has used, as it could have gone through the fence perhaps. shadyplace 7, there were voles in our yard this year, but I do not see any holes nearby. campunala- thanks for the tips, I think I will cut them back and see how it goes. I noticed today that my butterfly bush is starting to do the same thing, I just put in a 50ft perennial bed and I am concerned it is going to take over my bed. Thanks for your help. |
