Hi there!
I'm new to growing blueberries, and mine are currently two years old. I'm concerned about the color of their leaves; they appear light green. Is this normal, or could it indicate a deficiency in iron or nutrients?
The soil is acidic, specifically bought for blueberries, and they are watered regularly (unfortunately with tap water). I've recently added new pine bark mulch, acidic substrate, and bio pellet feed for blueberries/cranberries in early spring. Drainage is good as they are planted in felt growing bags.
The varieties I have (in order of photos) are Legacy, Duke, and Pink Lemonade.
I suspect the pH of the soil might have dropped due to tap water. Should I add a soil acidifier? The issue is that here in Croatia, we don't have a product specifically labeled as a soil acidifier. Instead, we have granulated sulfur. Would that be suitable?
