Hi. First year to grow Mammoth sunflowers . They are apx 7ft tall. (they are exciting to watch:))
Curious as to when the flower head starts to set. Do they put on all their height first? and then the seed head starts to form?
Have you no flowers?????
Ususally the flowers start and the stalk keeps growing...and growing....and....well you know!
Oh, no. I don't have any flowers. Sucks. A large storm just passed dumping two more inches of rain. So, maybe, they will set flowers soon! I'll let you know. TY for replying.
