Hi,
My nigella - sown 7 weeks ago - are teenie tiny. I sowed about 30 and gave 15 away to my neighbour. She planted they out and they are tall and flowering. Mine are only 2 inches above ground.
She has done everything I did. I think she watered less - I know they like dry soil, but I didn't water so much.
what do you think i could be doing wrong?
