My phlox get so tall, can I cut them back? I have heard you can cut back some plants until July and that they will still form blooms and be able to bloom. Is phlox one of them? I am referring to the old fashion phlox not the newer version that you buy in the garden centers now.
The old fashioned phlox is pretty much indestructible. You can cut it back and it should still bloom. Cut it back in fall or spring.
What would cause the buds of my tall phlox to fall off? I have been watching them with baited breath waiting for them to bloom and I was weeding the garden and found that most of the buds had fallen off onto the ground, what would cause this? HELP!
I am wondering if your phlox was recently planted. Often, if buds are on a plant when first planted, those will drop off due to a change in environment. If the phlox has been there a while, check its growing requirements below, such as watering, light, etc.
Check, too, for any insects that may have been feeding under and around the buds. I did some research and this is not a common problem of phlox plants, so I'm wondering if it is a cultural issue, like too much water.
I have garden phlox and need to know if I should cut them back in the fall.
Pruning like that before dormancy begins can make the plant go into “grow mode”. I wait until the phlox plants have browned out and gone dormant before pruning them.
