Blueberries stopped ripening mid season?
I have grown these blueberry plants in a large pot for more than 6 years now. Lately, for past couple of seasons I noticed that the container soil began to show some lack of nutrients, most notably iron, that made the plants suffer.
Anyway - I bought iron in liquid form and immediately after saw the plants put out active growth. I applied a second application (both at half the recommended strength to avoid overdosing), and now I found that there is plenty of vegetative growth but all pre-existing blueberries have kind of stopped ripening.
Typically, this time of the year is peak production time for them and now I see lots of plump berries getting plumper but not turning blue.
Should I be patient or is this a well known issue with excess iron application?
Thanks in advance!
