Love fresh spinach but have trouble getting a pretty crop. I get a lot of yellowing, is this due to pests or soil nutrients? |
Spinach is a cool season crop and grows best in rich moist soil with a pH of 6.0 or above; it will bolt or go to seed when the weather gets warm and this can make it look poor. Another possible cause would be what is sometimes called blight but is actually cucumber mosaic virus. You might look for CMV resistant varieties if you think this might be the cause of the yellowing. |
