Help please - my cosmos have all started producing flower buds at 6" tall
My cosmos bipinnatus 'Capriola' seeds dutifully germinated in February and started growing, and I potted them on at the end of March into 3" pots as recommended, but 90% of them started to form flower buds at only a few inches tall. I pinched out all the flower buds, but the resultant side shoots have all done the same thing, and the little plants are sparse and leggy rather than bushy, and only 4 of the 30 seedlings are now ready to be planted out. This variety is supposed to grow to 30", so they shouldn't be forming buds for another two feet! What am I doing wrong? Can I save them, and if so how? Any advice welcomed.
