My sunflower has developed brown blotches surrounded by black borders.
What
is this? Is it detrimental to the health of my sunflower? How do I
treat
it?
Thanks,
Adam
What shape are the blotches
What has the weather been
What fertilizers have been applied
What is your watering practice
Do the blotches cross leaf veins
Treatment is unlikely, prevention might be possible.
The blotches are of irregular shape. They cross leaf veins. The weather
has been somewhat stormy, but the blotches appeared before the storms. I
water the sunflower thoroughly once a day (it's in a pot). I have not
applied fertilizer but there is a slow release fertilizer in the potting
mix.
