Phlox Tiara flower buds turn brown before they even open
Hi everyone....I have a phlox tiara that is in its 3rd season now and I have never actually seen its flowers opened properly. The flower buds seem to turn brown before they even open. Also, I bought it as 4 stems and it is still 4 stems now while my other phlox have tripled in number. I would appreciate your kind help. Thankx!
