Pot no. 3: Getting full sun, 1 in a pot - tallest and fattest among all.
Comparing Pot no.2 and no.3.
So the conclusion is, sunflowers need full sun and plenty of space to grow. Each sunflower needs a lot of nutrients from the soil, planting several together will just mean each plant will get less nutrients. I didn't follow the rules when planting them because i want them all in white pots and i haven't got time to paint the empty pots white yet - yeeee, is my white obsession getting serious?
Thank you Diana for the seeds!
