Maurice - THAT is an excellent photo! A photo speaks a thousand words!!
I requested it added to the daylily database under "Wynnson". If no one else beat me to it and any acorns are awarded ... I will give those acorns on to you! YOU deserve them for this great photo!
So ....
Let me wrap my head around this .... Daylilies produce new roots and fans on TOP of the previous year's growth. So the plant should be moving UPWARD in the soil, right? Yet some are being pulled down by their roots? Pulled down more than they are growing upward? Why would that happen is the big question! What eventually happens to the old growth ... it dies off?
