Hi Folks We are growing figs in our 26’ X 48’ high tunnel for the first time this year. We planted tomatoes and peppers as the understory. We’ve had a blisteringly hot summer in Maine. The humidity in the high tunnel was high despite our opening the side walls for cross ventilation each day.
Our Smith fig developed what appears to be rust on the leave (rough and not glossy) and a few of these black dust areas. We planted too many tomatoes and they likely helped to hold in some of the humidity. Oddly only one of the smaller figs surrounded by tomatoes has this the others are not suffering from this. Just the Smith. The tree is fruiting, some leaves are curling up brown and falling.
We grow organic. Can anyone tell me what this is and how I can treat it organically? Pictures attached.Brown%20leaves%20on%20Smith%20IMG_2968%209-12-18|640x480
