Blueberry leaf issues, help please.
Have 7 container blueberries that are basically growing really well, but one of them recently developed a brown leaf problem. I noticed it yesterday and removed the bad leaves kind of hoping it would go away, but today I noticed more of the same. Not sure what it could be. They are growing in pine bark and peat, and we had alot of rain in the last 6 weeks, so I didn't think it was a lack of water issue, and the plant never wilted. I did fertilize recently with ammonium sulfate at a rate of 1 tablespoon per 2 gallons, but I washed it in really good. Have been using the same fertilizer routine on all blueberries for 3 years and have never had any kind of fertilizer burn. Thanks. Ed
