Doesn't look like disease. More like wet, cool, and just getting established. They also look nitrogen deficient but could just be above. After they get established a bit you might try adding small frequent additions of nitrogen. In NY you probably don't need lower pH so something like Urea or cottonseed meal would be a good nitrogen source. If you do need to lower pH then ammonium sulfate, 21-0-0, is a good choice. Both urea and 21-0-0 are best dissolved in water at about one tablespoon per 2-5 gallons water and poured around the plant.

Hi Folks again. So Over the summer, 2 of my plants did well. I is doing ok. and one is in trouble. PH seems to be ok.. its around 4 from a soil sample on the top. I am confused. Attached are 2 photos. I is the plant in trouble. One is one of the plants thats doing ok. they are 3 feet apart and have been fertilised with cottonseed meal, and have added epsoma acidifer granules. they were both planted with spagnum.

Need advice - do not want to lose this plant. Its a DUKE

Just curious. Are you watering too much? The ground looks soaked.

I actually shut off the soaker hose today also thinking that that may be an issue with all the recent rain. there is good drainage. I also watered the all the plants with a mix of aple cider vinigear - 1/3 cup in 2 quarts of water today so that may be why it appeared to be over wet...

Hi doogan,
What's the pH of your water without and with the addition of the vinegar?Brady

That sounds like a lot of vinegar. I have 2 container blueberries, growing well, and my tap water is about 8. I add 2 tablespoons (1 ounce) of vinegar per gallon of water, which brings the pH of the water down to about 4. 1/3 of a cup of vinegar per 2 quarts of water would be more than 5 ounces of vinegar per gallon of water.

brady - thats a good question. I need to pick up another test kit. I will be back.

In ref to the vinegar - I found a blog posting online.. not sure how valid.. but recommeneded a 1 cup to a gallon...

1 cup per gallon? Yikes! Maybe it's me that's crazy, but that sounds like WAY too much. Just my worthless opinion.
