Mark Anderson expounded:

I have a couple of potted sunflowers with leaf problems. The lower
leaves are turning yellow and dying on one massive sunflower and on one
of the chianti sunflowers the leaves are blotched. I put them up at:

I have other potted Chianti and massive sunflowers with no problems like
this and getting similar amounts of light. Is it a soil problem or
water? All sunflowers were planted in 16" high 12" x 12" containers.

Mine do the same thing every year, I just remove the leaves, and mine
are planted in the ground. Looks like you have an interesting
container garden going there, have you grown sunflowers before in
pots? Very nice!
